Noticed this when exploring another optimisation
By specification exactly which overloaded function to use
we save some memory
Seems to have something to do with doing arithmetic in the function argument
Change in memory:
Flash: -156 bytes
SRAM: 0 bytes
There is no need to repeat:
lcd_update_enable(true);
lcd_update(2);
Also lcd_clear() is redundant because lcd_update(2) will clear the LCD

Flash: -16 bytes
SRAM: 0 bytes
Previously when the firmware called M701/M702 manually
there was no Z lift. But after we added support for the Z
parameter we set the default to 50mm.
Change strings "M701" to "M701 Z0" and "M702" to "M702 Z0"
to restore the previous behavior from before 3.13.
Also pulled the gcodes into PROGMEM in message.cpp
along with M83 and M84 to save memory.

When the extruder lifts up after completing the Purge line,
the baby stepping is not allowed for a short time. This dismisses
the menu. We don't want this behavior, so only apply the Z-axis requirement
when printing.
Change in memory:
Flash: +8 bytes
SRAM: 0 bytes
Add lcd_commands_type == LcdCommands::Layer1Cal
just in case blocks_queued() is 0 for one instant between
lcd_command steps

Fixes an issue with running first layer calibration twice in a row.
Improvements:
Now the Z baby step menu closes automatically when first layer calibration is done.
No need to wait for a timeout or close the menu manually by setting a variable
If the baby stepping menu is open, and suddenly
the printer enters a state where baby stepping
is not allowed.
The printer will save the last value before closing the menu.
When LcdCommands != Idle, don't dismiss
the Z baby step menu. This saves 20B

* M600 used 1°C threshold, which may increase the waiting time a bit
* Wizard used 3°C
Sync both to use TEMP_HYSTERESIS for consistancy
No change in memory footprint
- Expose TEMP_MODEL_fS and TEMP_MODEL_LAG as D and L respectively,
initializing the default values based on the previous hard-coded
values.
- Always round L to the effective sample lag to future-proof model
upgrades or changes (the stored value _is_ the effective value).
- Introduce UV as a new linear term for PTC heaters, defaulting
to an identity for model backward-compatibility.
On printers without the MMU no error screen should occur and no attempts of communication with the MMU should be performed -> EEPROM_MMU_ENABLED should default to 0.
PFW-1418
Use "echo:" for thermal model error reporting to avoid octoprint
automatically sending a M112 kill.
Keep using "error:" instead for other thermal errors (MAXTEMP/etc).
This should allow resuming a thermal mode pause with the default
octoprint settings.
Main changes:
* setAllTargetHotends() is removed
* setTargetHotendSafe() is removed
* Extruder parameter on setTargetHotend() is dropped
Change in memory:
Flash: -192 bytes
SRAM: 0 bytes
The function adds a bit of overhead compared to code_value()
I suspect this function is a relic of the past.
Change in memory:
Flash: -82 bytes
SRAM: 0 bytes
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.
