Running `M310 A` should set the TM calibration bit status if the
autotune procedure was successful.
Partially addresses #3891 and #3890, since running `M310 A F0` should
*still* count as valid calibration data and is not something that can be
replicated by using the LCD (which enforces self-test).
This fixes#3891 without having to set the calibration bit, meaning
that if the model is later re-enabled without a real calibration, a
prompt is shown as expected.
Alert messages are intended to persist above "info" messages, thus
preventing further calibration status updates to be shown (such as
thermal model calibration).
Just set the message as a regular status message.
Fixes#3892
It was only enabled when multiple extruders are enabled
The firmware doesn't support it
and even if the M218 gcode could be used, the code does not compile
Disabling the model during a warn/error condition will also stop
updating the warning/error flag, keeping the printer in an error state.
Clear all flags as well when changing model settings.
Follow Marlin's behavior and simply insert a delay for the requested
duration when using M300 S0.
When S is not specified, use the default tone instead.
Fixes#3856
This PR tries to address the 3 different startup scenarios for 1st layer calibration with the MMU:
- 1st lay cal started with correct filament already loaded in the nozzle - we should continue, but skip the first 58mm (first 2 g-codes in the hard coded sequence) of purge line extrusion
- 1st lay cal started with other filament already loaded in the nozzle - we should unload and then issue a toolchange with no extra unload
- 1st lay cal started without loaded filament - we should just do a toolchange with no extra unload
PFW-1457
This is a prototype implementation of having the ability to show an MMU error screen even for printer's errors (during an MMU operation).
Also, the retry count of unloads after failed load the extruder tube is now limited to ~3 attempts.
Technically, since this very error is not an MMU's one (MMU is just fine at this stage) but a printer's one I tried to hack the existing error-reporting infrastructure to handle such a case.
The original idea of this approach was suggested by @vintagePC
Instead of checking for explicit versions, resume the wizard if some
(new) wizard is missing.
This handles both the old SELFTEST check, the new thermal model
and any future check in the same fashion.
Update the eeprom FW version as soon as migration is complete, to avoid
resetting the CALIBRATION_V2 variable at each reset.
Do not implicitly reset the calibration steps for WizState::Run: do this
only for the menu action.
- Handle the conversion from the V1 calibration status to the V2 bitmap
for all past FW versions.
- Allow to run the wizard in "Restore" mode (for example during upgrade
or service prep) to complete any missing steps.
- Fix service prep to use the above feature by clearing the appropriate
calibration bits.
- Remove exceptions for FW 3.2.0.4 which can now be handled cleanly.
Simplify status tracking:
- S::Restore to continue to the next logical wizard item
- S::Finish for a successful failure
- S::Failed to exit while showing a failure
- Move calibration status/declarations to util.h
- Allows to query the status of each step independently without assuming
any order
- Allows to extend the calibration with new steps transparently
- Generalize force_selftest_if_fw_version() so we can check when upgrading
between arbitrary FW versions.
- Do not call update_current_firmware_version_to_eeprom() prematurely
when forcing self-test (if a reset happens before self-test completes,
the check would be incorrectly skipped on the next run).
Expect these to be always at the start of the command (which is now
stripped of the extra line number), reducing the number of corner cases
due to these not following the g-code spec.
Instead of reading and checking if a character is a whitespace
just print it out onto the LCD. This makes the code a bit less
complex. Whether there is a whitespace character, we always end
up reading from program space, so I doubt this has much performance
impact.

The Extra Loading Distance is configurable by the user.
We need to compensate the hardcoded sequence
such that it does not extrude too much or
too little. Currently the firmware
extrudes too little.
Fixes issue where First Layer Cal. triggers an unload before any
filament is loaded
The purpose of this if() statement is to handle the case where
a user or developer is sending T-codes to the printer directly
via Serial. Such as when one first sends T0 and then T4.
And unload must be triggered in-between, we can do this automatically
if FINDA detect filament.

If there is no running print, and the printer is Stopped, add a new
"Acknowledge error" menu entry to unlock the printer.
This simply calls lcd_print_stop(), which is identical in behavior to a
thermal error with a running print.
Set a menu block for fatal thermal errors instead of abusing
lcd_return_to_status() to kick the user out of the menus.
This now allows a thermal model error to be recoverable through menu
access.
We allow resuming from the LCD via start print and resume print,
it makes sense to clear the error on stop too.
For this reason distinguish whether the action is performed
automatically or manually (ie: interactively).
The error is only cleared when the command is run interactively.
The printer shouldn't continue endlessly asking for a version if an old MMU is detected.
Also if the protocol is supposed to be turned off, it
shouldn't be sending S0 queries.
In M600 and M702, the Z-lift is taken care of outside this function
so it makes no sense to have a Z-lift within unload_filament()
Only exception to this is in the wizard, there I moved the Z-lift to
happen before we start heating the nozzle.

Ensure that fan checks are reset and use the new speed at each step of
the calibration.
This also gives extra time to the fan to ramp-up from a cold start,
when a fancheck could previously start right *after* the speed change.
Should fix#3791
Since M310 cannot change the heaters, allowing M310 S0 (and changing
parameters) allows to recover a usb-controlled printer which has been
locked-out due to bad model settings.
This prevents the ability to run gcode from the SD card.
In a thermal error with faulty values, and without serial access, this
is the only way to process an M310 instruction and recover.
- Correctly sequence the enqueued commands in order to check for the
real calibration result.
- Perform autocalibration with self-check enabled.
- Only save/continue the wizard if autocalibration succeeds.
- Ensures repeated autotune attempts with self-check can't succeed due
to different starting conditions.
- Allows for a simpler workflow during selftest and wizard if autotune
fails.
Provide average calibrated values for all fan levels for MK3/MK3S
variants and enable the model by default.
This ensures the calibration step is not skipped unless explicitly
disabled.
Force-clear fan values during autotune to restore the previous
calibration behavior, as fan resistance levels can be too big and
prevent the autotune-with-selfcheck to fail.

It's only used when MESH_BED_LEVELING is not defined. According to
the configuration files, all printers supported use MESH_BED_LEVELING.
So I think we are safe in removing this dead code.
The firmware saves the current fanspeed before parking,
and the fanspeed is restored after unparking. The problem is the fan
was never actually paused.

This code was introduced with v3.8.0 but was always disabled.
I propose the code be removed since it has not been enabled

So in an ideal scenario, the newest file is first. This of course breaks as soon as a file is deleted/renamed/moved, but it should at least be fixed now compared to before where the direction could be influenced by a disabled setting
This piece just changes the default extra load length on the MK3 side.
The same needs to be done on the MMU side but:
- the MMU exposes its register for this (so we can change the extra load distance by writing into the register via G-code)
- the printer shall probably set this value on its own after line up of MMU communication
In Idle and Command mode it is now possible to specify a list of registers which shall be periodically read from the MMU.
To keep the code and RAM size down registers are intentionally separated into 8bit and 16bit sets.
Adding a register into the set is just a matter of parametrization, there is no need to change the state machines anymore.
I had a crash when producing an error screen and printer was unhomed.
Extruder was located at the far right side, and immediately crashed when attempting to park.
If you generate a multicolor gcode file with PrusaSlicer, the purge
line gcode will look like this.
This reduces clicking sounds from the extruder, filament extrusion is reduced by 6mm.
Instead of including Configuration_prusa.h directly, include
Configuration_var which then includes the proper variant file though a
preprocessor macro.
This allows to keep the existing build system intact, but also redefine
at compile time the final header without having to make copies on the
file system.

This should set the EPOCH using the last git commit date when available,
but it's not currently implemented. Just set the EPOCH to be 0 for now.
Removes a missing return warning.
Looks like we don't handle overflow at the moment and in all surrounding
code, so let's remove the return value for now.
This generates a warning under -Wextra, since in most cases a const
value doesn't prevent buggy code (as copies are allowed) while
preventing some optimizations (such as move operations) to take place.
Consume any pending LCD click after the temperature model calibration.
Since we're already in the status menu, the usual consume action is not
done automatically here.
The current code forces any warning to return the user to the status
screen in order to show the message.
Thermal anomaly warnings can repeat at very short intervals, making menu
navigation (to pause/tune the print) impossible.
We now check if the message to be displayed is the same and only force a
kickback for new messages.
This partially reverts https://github.com/prusa3d/Prusa-Firmware/pull/3600
since we need the string to be null terminated for ease of comparison.
We pad the status line at display time instead using the new
lcd_print_pad() function which achieves the same effect.
In ultralcd_init() do not use lcd_setstatuspgm() to initialize the
welcome message.
The internal call to lcd_finishstatus() requires the serial to be
already available. Split the function into lcd_padstatus() to pre-pad
the string and save some space.
Fix regression introduced in fc10ca3146.
Accept incoming serial commands without line numbers (assumed to be
injected by the host), but do not reset the last line count when doing
so.
Now that lcd_status_message is now initialised correctly at boot-up,
this for-loop is no longer required. Now lcd_status_message is
only set in lcd_updatestatus() which always calls lcd_finishstatus()
lcd_finishstatus() makes sure the message does not exceed 20 characters
Saves 34 bytes of flash
static variables are automatically zero initialised. Now that the
status line message is initialised in ultralcd_init(), we don't
need to set the variable in global scope.
Saves 22 bytes of flash and 1 byte of SRAM
Since mmu_loop() is called in the main loop() function
when the MMU is disabled, we need to utilise the
MMU protocol layer to prevent FINDA runout from happening
if MMU is disabled.
We also need to keep in mind we probably can't trigger
a FINDA runout in the middle of a Q0 query.
So my solution now is to wait for the "Finished" state
and check if the FINDA is off during printing.
When "Finished" state appears, the FINDA value should be up
to date.
During first layer calibration we have the live Z baby step menu
on the LCD and the user can tune their Z offset live.
Once the first layer calibration is done, we want to exit the menu
immediately. For this purpose it is much more efficient to
call lcd_return_to_status(). There is no visual difference
on the LCD for the user.

We want to move the Z-axis after the XY move is done.
raise_z cannot be used here because it relies

If the endstops kick in, then st_get_position_mm shows the actual travel distance. current_position[Z-AXIS] does not get updated correctly thus we cannot use it when unhomed.
current_position[Z-AXIS] is later set to Z_MAX_POS,
we cannot use that either to calculate the travel distance
Removed the "plan" parameter.
We were incorrectly returning from the function if the printer was homed,
but plan = false. This would leave current_position with an incorrect value
If the printer is homed => finish the move and return the travel distance
If the printer is not homed => rely on end stop to prevent damage,
return travel distance even if the endstop stopped the move.
The current unload sequence does not give good results.
The Marlin 2 sequence looks good on my end. This can be later
used to improve M600
Added all the constants from Marlin 2
* Created a new function raise_z() which will move the Z axis by some
X millimeters. If plan = false, the function will return the
actual travel distance since the move is blocking.
* raise_z_above() is refactored to call raise_z()
Now the M701 and M702 will move the Z-axis relatively, and also
when done, revert the Z axis position when done.
This is a similar behavior as in Marlin 2.
It is only used when the MMU is disabled. With the MMU we use a defined ramming sequence.
When the MMU is disabled I borrowed the usages from Marlin 2.
The L parameter only defines the length for the "fast" load length.
Default value is 70mm, same as M600
- remove virtual methods (we only have one fsensor implementation at a time)
- comment out some of the debugging texts
- remove volatile and replace them with proper synchronized access to relevant variables
Don't start moving the E-motor immediately
Instead of starting the E-motor move when the load to extruder starts,
we can start when we are loading to the fsensor. At that stage
the MMU has changed from a fast load to a slow load.
Because it looks like the communication drop outs are caused by some electrical issues and we can loose even a byte from the version response, which is deadly for future operation.
When a Progress report is started, we set the CustomMsg to MMUProgress.
But there was an issue where, once the reported "Progress" action was done.
We did not reset the CustomMsg to Status. So if we are printing from the
SD card, the file name is not displayed on the LCD.
Communication timeout and Protocol Errors are now distinguished.
In case of a Protocol Error, the printer waits for heartBeatTimeout to allow filling up the input UART buffer (we expect the MMU still produces some bytes).
Once the timeout elapsed, the input UART buffer is cleared and a new Start Sequence is initiated.
Fix the unload procedure when the user has paused a print
then stopped the print after the temperature has reached below 175°C
Now the E-motor will move as expected
This is a draft PR showing the potential 3x retry implementation on the printer's side.
It is much less code and looks more reliable than the same functionality in the MMU FW.
Still, more work needs to be done:
- [ ] Button is sent to the MMU even before returning from the parking position
- [ ] Then the button is sent again
- [ ] Then the printer runs out of retryAttempts
We need to find a better spot to check for "automatic" retry and issuing of the buttons
* Fix MK3S buttons being processed too slowly
After a button is selected on the MK3S MMU error screen, we need to process it before asking for another MMU Query.
Because the MMU Query will make the Error screen return and overwrite the status screen
* Add back CheckUserInput for ButtonPushed event
When a FSENSOR error happens, the first step for the MK3S should be to stop any loading by stopping the E-motor.
From this point, the buttons should determine what the MK3S does next.
* FSENSOR_DIDNT_TRIGGER
* FSENSOR_DIDNT_GO_OFF
The Done button does not Move the E-motor because it
expects the user to have manually resolved the problem
Also if the filament is in the gears, we cannot pull the filament out.
In this case the Retry button is more suited as it will unload the filament.
lcd_encoder_diff would be set to 0 if lcd_update_enable(true)
is called outside ReportErrorHookMonitor
This would put enc_dif out of sync with lcd_encoder_diff and could cause false rotation triggering
It turned out the runout is caused by the ramming sequence in the G-code, which is interpreted before the actual MMU command gets into processing.
The frequency of these errors/runouts differed one machine from another and was really hard to track down.
Therefore - once the MMU is enabled (active and running) we'll disable filament runout handling caused by the printer's filament sensor.
There are still printers which suffer from spurious runouts for no reason.
For testing purposes, runout will be disabled until the real cause is found.
The following situation is now fixed, steps:
1. Load filament through LCD
2. Load to nozzle through LCD
3. Before filament reaches Fsensor => turn off the printer
4. Wait a few seconds and then turn the printer on again
5. Start a print through the SD card
6. Printer will unload and then re-load the filament
Previously in step 6, the printer would start a print without any
filament loaded.
- Dependent on current MMU error being processed
- Includes rename of LEFT_BUTTON_CHOICE -> LCD_LEFT_BUTTON_CHOICE (and right, middle as well) to avoid confusion with MMU buttons' ordering
To render the thermometer and degree symbols
the CGRAM table will instead swap out
the feedrate and clock symbol when
lcd_set_custom_characters_nextpage()
is called.
- We need to take into account additional 35mm move by the MMU.
- While the fsensor is not triggered, reduce the extruder movement each step from 20mm to 5mm. This should help reduce the variance in the filaments position before we run the final load to nozzle sequence.
- Fixed a bug where the feed rate was 60x higher than intended
- Adjusted the sequence via trial and error. The sequence where the filament has not exited the nozzle is 35mm shorter than the previous implementation
- I reduced the feed rate slightly (by 1mm/s) on the fast load sequence
- combined lcd_show_three_choices_prompt_P and lcd_show_two_choices_prompt_P into one function called lcd_show_choices_prompt_P
- Removed third_col parameter
- Added an enum to make the button selection result more readable
- Rename lcd_show_multiscreen_message_two_choices_and_wait_P to lcd_show_multiscreen_message_with_choices_and_wait_P
- Move MMU error screen from ReportError() to ReportErrorHook()
- Fix the menu selection to work for menus with either two choices or three choices
- The buttons shown on the MMU error menu are now determined by the definition of btnOperation[]
getFilamentPresent returns the state of the IO pin of the sensor.
So we should use AT_FSENSOR instead of IN_NOZZLE
since the fsensor does not know if the filament is actually in the nozzle.
Such that:
MMU2:E=32766ErrorTitleTextDescription
Becomes:
MMU2:E=32766 ErrorTitle TextDescription
Also simplified the process of combining ErrorTitle and TextDescription
into the msg buffer by using snprintf. This is saver since we only
use dstSize in one place instead of two.
This could cause the printer to crash. The Serial Stream would show
a garbled string.
Also included in this commit:
* The buffer size is increased from 64 bytes to 192 bytes. We need to
take into account the length of the ErrorTitle and ErrorDescription.
* Fix overwrite in ErrorCode message buffer.
When snprintf() if called we need to read the return value to see how
many bytes were written. Then when we call strncpy_P() through
TranslateProgress(), we need to tell the code to start writing
at byte 'len', or &msg[len]. Also we need to update the byte size
which strncpy_P() is allowed to write (64 - len).
This could cause the printer to crash. The Serial Stream would show
a garbled string and the same corruption would appear on the Status
Screen's status line.
makes the code a bit shorter as well, because the compiler can be sure
that the variables are not accessed from the outside of the
fsensor.cpp compilation unit.
Update fw-build.sh
- Output used space of each translation (easier to troubleshoot)
- Read config.h max size per translation
- output variant .map files (easier to troubleshoot and finding missing/unused messages)
This message is never actually shown on the LCD (it's immediately
overwritten by other content). It also include g-code in a translatable
string, which is not a good idea. It's also otherwise identical to
MSG_V2_CALIBRATION, which we should have used.
Just remove it and save some space in the process.
Having the original PRINTER_ACTIVE macro copied at multiple spots doesn't make sense.
Refactoring it into a non-inline function saved ~400 bytes of code.
It should be safe in terms of performance, all occurrences are at non-time critical spots.
Add an additional parameter to control the position of second choice
prompt position (while defaulting to the old).
This allows Yes/No prompts to be equally spaced.
Modify lcd_show_multiscreen_message_two_choices_and_wait_P to also
handle single-screen or empty (no-clear) prompts, making other functions
redundant. Saves 76 bytes.
Change existing functions to simply call
lcd_show_multiscreen_message_two_choices_and_wait_P with the correct
arguments.
This changes the prompt of existing Yes/No messages: the previous prompt
would use the last two lines of the LCD, while the new prompt is using
just the last line of the LCD instead.
Translation do not require updates, since the Yes/No translation was
already the same in both implementations.
Allow running the model checking during autotuning, with the only
exception being the parameter estimation stage where we alter the same
value which is used by the checker (done to conserve memory/code).
With previous changes the model checker will disable/enable itself when
passing through an unavailable R vector entry, allowing to start the
calibration by checking only the stages where the part fan is disabled.
The C/R0 values should be stable enough to provide a fail-safe mechanism
for printers of the same variant right from the factory.
Instead of assuming the model state is always valid, allow NAN values to
pass-through the various check/estimation stages.
This allows running the model checker with incomplete parameters (for
example, missing entries in the R vector) and resume automatically.

Split the planner sync code out of planner_abort_hard() so that we can
independently resync the planner position from the counters.
This is needed in xyzcal as we directly modify the stepper counters
(bypassing both planner and stepper).
Call this new function instead of planner_abort_hard() when leaving, so
that motion can resume in the middle of the gcode_M45 instruction.
We already disable the heaters upon entering, and the new temperature
isr doesn't perform any direct movement until we return to the main
loop.
This allows us to remove direct control of the soft_pwm interrupt from
the header, which is dangerous.
printer_smodel_check was incorrectly substituting the final " with a
null in the command to simplify the model string comparison, but in
doing so was also corrupting the next pop from the cmdqueue.
We can modify the current strchr_pointer as long as we *don't* change
it's length. This can cause an incorrect extra read from the queue,
resulting in the last command to be completely ignored.
cmdqueue will run commands when EOF is reached without returning to the
main loop, which is already incorrect.
However, since it needs to ensure the queue is empty, an st_synchronize
call can result in a re-entrant call to get_command, which will
reprocess EOF again. Even if we removed st_synchronize, another command
could be picked by an unsuspecting manage_inactivity() somewhere else.
Short-circuit EOF processing by closing the file early and checking for
the file state early in get_command.
This should fix#3549
Call this variable menu_block_mask instead. We don't need to know the
exact reason of why we're locking the menu.
We will be able to reuse this to prevent menu entry during more
activities in a cleaner way than testing for each condition as it's
currently done for both menu entry and longpress.
This allows us to use "M310 B0 W0.01" as a way to report the current
error continuosly on the serial without 1) more code and 2) without
preventing regular usage.
Use OCTOPRINT_ASK_* for the present form of actions. In these cases the
host will perform the pausing manouvers for us.
Use OCTOPRINT_* instead for the past tense forms when we are in charge.
Also always emit the action, whether we are or not sd-printing. This is
due to the new Stopped handling behaving correctly in either case.
If the user accepted to resume, do not wait for bed temperature when
recovering. This only adds a pointless delay when recovering a short
pause and doesn't really improve the recovery quality after a long
pause.
Do not allow resuming until all thermal and fan errors are clear.
Call the appropriate resume function when resuming a printing depending
on the saved_print state (is saved_print is available, then we always
need to resume from the saved state even when printing via usb).
Clear the Stopped state when resuming, so that commands can be accepted
again.
Ensure we never fall into the boundary values provided by the min/max
limits.
Save/restore the initial guess value, so that a convergence failure
restores the initial model state.
Force processing of the pause and stop "parking" commands _after_ the
main loop completes.
This was/is currently done in lcd_commands, which is a poor place to
continue processing, since it can be called already within an aborted
command. This requires checking for planner_aborted before any action
can be performed.
After calling planner_abort_hard() no motion command can be
scheduled until we return to the main loop since the call can
potentially be scheduled inside a nested process_command call.
Despite previous fixes, bugs keep creeping in due to nested calls not
being obvious to detect at all.
Stop allowing motion _completely_ for the entire processing loop by
default. That is, instead of aborting the current plan_buffer_line call,
abort the entire command until we can actually schedule motion safely
again.
This benefits handling of pretty much all g/m-codes, since this flag
(now "planner_aborted" for clarity) becomes a general "command aborted"
call.
This also now ensures that the flag prevents _any_ new block (including
blocks partially planned while servicing an interrupt) are scheduled
after planner_abort_hard is called.
There are only two exceptions where it's safe to resume in this context:
- Within uvlo_, where we never return to the main processing loop
- When we're intentionally scheduling a new process_command loop for a
MK3 filament recheck (which is *bad*)
Handle those two cases as exceptions.
Do not inhibit motion when Stopped is set.
We actually do need to move to move away the extruder from the bed, and
setting Stopped breaks it without adding any sort of security (M*
commands, such as M600 could still perform moves and still pass
through, while M104 would still set heaters).
During a hard error the internal queue is cleared (and sd file closed,
if any), so no new "unforeseen" command can be read.
Handle "Stopped" instead as a flag to inhibit serial processing and
automatically switch to "paused for user" state. While in this state
simply drop any input without incrementing the processed gcode line
number, behaving as-if the last command was still being processed.
This allows "Stopped" to correctly handle a printer-initiated paused
state and recover as expected by requesting a resend when resuming.
Add a new LCD_MESSAGE_INFO priority which can be overridden by regular
status updates, but only if a certain amount of time has passed.
Assign a time stamp to all message updates, so that the time since the
last update can be determined. Also switch the message type to Status,
so that the message always becomes visibile.
Always show status or info messages when printing via SD if the message
is recent enough.
Remove useless repeated calls to disable heaters and turn on the fans,
since this is done at a higher level.
Avoid repeating messages on the serial. Do it just once.
Make a critical alert sound unconditionally.
Break out of the autotuning if a thermal error condition is detected and
attempt to restore a safe initial state irregardless of the error
handlers.
Also error out if the estimation fails to converge.
Calibrate C/R values via univariate minimization using golden section.
This is done in several passes:
- Bootstrap C by setting an initial high R value
- Calibrate R at the requested working temperature
- Cooldown
- Refine C to the final value
- Estimate R losses for a subset of fan speeds
- Interpolate remaining values to speed-up the process
This results in robust values which are tailored to the current
filtering constants, and avoid having to sample for an extended
time to reach the required resolution.
The refining pass could avoid cooldown if the recording buffer was at
least twice as large, so that we could record both the heating and the
steady-state, saving _considerable_ time.
This currently bypasses the ConfigurationStore, which doesn't fit the
malin model nicely.
temp_model is using it's own private copy directly.
But maybe we should change this in the future.
- Allow all parameters to be changed at runtime through M310
- Move the model prototypes into a separate temp_model.h header
- Allow the checked to be enabled/disabled at runtime
- Introduce a warning threshold
When triggering a thermal error, allow higher-priority errors to
override the initial error source.
This allows a fatal error such as maxtemp to trigger to a full stop even
if thermal runaway has already been triggered.
Reorder error types according to their priority.
Do not overwrite the error source if the error flag is already set.
As checks are performed in priority order, this ensures min/maxtemp
user-level handlers are triggered even if the thermal model can detect
an issue in the same cycle.
This restores MAXTEMP handling, which was simply shadowed.
Setting pid_tuning_finished can result in the heaters stuck to full
power. As a result, we need to ensure that when PID management is
disabled, heaters are also.
Use pid_tuning_finished as a flag to prevent automatic PID management.
As a result, set the default start-up state to true and adjust the
dependent code accordingly.
- Flag the error condition from the temp_mgr_isr
- Handle the error state from the user code
Currently only handles min/maxtemp and relays the error to the original
handler (which is a poor fit for the current design).
Split off setIsrTargetTemperatures and temp_mgr_pid() so that we can
propagate the target temperatures instantaneously down the pid/pwm chain
during emergencies.
This reduces the amount of code in disable_heater() itself, making it
a bit more maintenable.
The bed still isn't disabled on-the-spot yet, due to the heatbed_pwm
automaton. To be improved later.
*_temperature_raw: buffer for the ADC ISR (read by temp ISR)
*_temperature_isr: latest temperatures for PID regulation (copied from
_raw values)
*_temperature: latest temperature for user code
The flow:
- ADC ISR (async)
- perform oversampling
- call ADC callback: copy to _raw (async)
- temp ISR (timer)
- convert to C (_isr values)
- user code (async)
- check temp_meas_ready
- call updateTemperature()
- copy from _isr to current
- syncronize target temperatures
This removes PINDA value averaging (if needed, should be re-implemented
by averaging in user code where needed)
Use a new low-priority "temp_mgr_isr" running at constant rate for
temperature management.
This is done so that the temperatures are sampled at a constant
independent interval *and* with reduced jitter. Likewise for actual
PID management.
This will require further adjustment for the min/max/runaway display,
which cannot be done directly into this function anymore (the code will
need to disable heaters but flag for display to be handled in
manage_heaters).
Read from ADC as fast as possible using the ADC interrupt to get
more accurate instantaneous readings.
Decouple the temperature_isr from the adc reading interval, so that
the two can run independently for future use.
Setting pullups on the ADC should trigger the model-based check, making
this redundant and wasteful.
Keep the DEBUG_PULLUP_CRASH menu so that we can verify this behavior in
the future.
Fallback to use the default HIGH value if a frequency has not been
specified.
This makes the tone of "M300" and "M300 P<x>" identical as a result.
