There is no need to read one byte at a time. We can simply
read the whole block in one go. This saves some flash memory.
Change in memory:
Flash: -18 bytes
SRAM: 0 bytes
We can just read the whole EEPROM block since short filenames
are always null terminated. strcat_P will then apply the file extension
at the correct position.
Change in memory:
Flash: -24 bytes
SRAM: 0 bytes
If the saved printing type was USB, then EEPROM_FILENAME
does not contain anything. The firmware should also
not be trying to open a file on a SD card which is maybe
not even mounted.
Change in memory:
Flash: +12 bytes
SRAM: 0 bytes
There is no need to restrict how often the message is rendered.
It was being restricted to render every 1 second. We don't do
this for most of the static menus. So I propose this 1 second period
be removed.
Tested on MK3S+

Flash: -168 bytes

My plan is to re-use this function in M79
in a later commit. The firmware doesn't
have a dedicated parser like Marlin 2.1
so this is my attempt to not duplicate the parsing of a quoted string in G-codes
Change in memory (MK3S+ Multilang):
Flash: -50 bytes
SRAM: 0 bytes
The idea is to have the host ping the printer periodically with a M79 to
enable certain features/UI. Using the usb_timer is not a good solution
for this as it depends on seeing a 'G' character
The LCD code, or whatever code is implementing the new functionality
will need to include host.h and check whether M79_timer_get_status()
returns 0 (timer not running) or 1 (timer is running).
I created a new file for the code host.cpp which we can use to expand
host related functionality and not clutter Marlin_main.cpp further.
Change in memory:
Flash: +104 bytes
SRAM: +5 bytes
Setting this state notifies PrusaLink/PrusaConnect
that the printer is waiting for user input (attention).
Change in memory:
Flash: +12 bytes
SRAM: 0 bytes
power_on should not be modifying
EEPROM_MMU_ENABLED. The code is never
executed unless it's already been set.
Only disable EEPROM_MMU_ENABLED through Buttons::DisableMMU
Change in memory:
Flash: -18 bytes
SRAM: 0 bytes
On my end, the default length for the abbreviated commit hash is 9 characters.
This won't fit into uint32_t (4 bytes).
Instead change FW_COMMIT_HASH into a string
and create preprocessor symbol for the string length
such that it's known at compile time.
If the string should be longer or shorter
then only FW_COMMIT_HASH_LENGTH needs to be configured on the CMake side
While waiting for the nozzle to reach a certain temperature, a fan error
should disable the hotend heater. If printing, it will simply pause the print.
Previously the printer would wait for the nozzle to heat up before pausing the print
and turning off the hotend heater.
We rely on LcdCommands::LongPause and must return to the top level loop to process it.
Waiting in the while loop e.g. in M190 does not make sense.
lcd_calibration_menu: Remove redundant if (!isPrintPaused). The menu
is never called unless this condition is true.
eeprom_switch_to_next_sheet: Don't show this menu if the printer
is busy doing work!
Do not allow these menus to run while a print is paused or
when we're recovering a print:
- Preload to MMU
- Load to Nozzle
- Unload filament
- Eject from MMU
- Cut filament
- Autoload filament
- Settings
- Calibration
There is a bug where if the printer is recovering a print, it run a
blocking loop to restore the extruder and bed temperatures.
But if a Fan error is triggered in this loop, then the user can't
abort the print via LCD.
If the fan error resolves on its own the 'Resume print' menu will
appear in a few seconds. But if not, then the user can't resume the print
(which is normal). But with the bug above the user can't abort the print either!
The problem is essentially isPrintPaused variable is cleared too early.
We should wait until the print is completely restored first.
Steps to reproduce:
1. Start a print
2. Pause the print
3. Wait for extruder temperature to fall at lest 180°C
4. Click 'Resume' print
5. While heating, stop the hotend fan and wait for a few seconds until an error is raised
6. Observe issue => 'Stop print' menu item is gone!

The status line code is not nice, but we need to work around it
so the status line rendering works correctly
This commit mostly reapplies the code
from 3.13.2
Also fixes compiler warnings
