This is an initial cut for feedback.
Chamber temperature is currently reported along with hot end and bed
temperatures to serial. The format is just like that used for hot end
and bed temperatures, but using 'C' prefix. As there is no heater,
target is always 0. Is this appropriate, is there a better way to report
chamber temperatures?
Chamber temperatures are not reported on the LCD in any way.
When auto chamber fan is enabled, it currently just uses the same
temperature threshold as the other auto controlled fans.
As the chamber temperature is not connected to any heater, it doesn't
undergo mintemp/maxtemp monitoring. This would need to change in the
future if chamber heating became a feature.
* Added M303 thermal runaway protection
Currently, thermal runaway protection is not available during M303.
Therefore, if someone plugs the thermistors in incorrectly and goes to
autotune their printer, the printer temperature could runaway and damage
could occur.
* Replace removed line, clarifying its logic
* Unify M600 and M125 pause features
* Cleanup per thinkyhead's comments
* Rename filament_change_menu_response to advanced_pause_menu_response
* Include HAS_BED_PROBE in QUIET_PROBING
* Update gMax example file
* is_idle() is out of scope without the braces
* Convert FT-i3-2020 to Advance Pause names...
* Allow pause even if not printing
- rename to PROBING_HEATERS_OFF
- move heater pausing functionality into thermalManager
- add variables, pause(), ispaused(), other functions
- add fan pausing functionality -> PROBING_FANS_OFF
- add probing_pause() wrapper
- move pausing into do_homing_move() and do_probe_move() to minimize quiet time and so other probe types can benefit
- example configs
If Marlin is inside the temperature ISR, the stepper ISR is enabled. If
a stepper event is now happening Marlin will proceed with the stepper
ISR. Now, at the end of the stepper ISR, the temperatre ISR gets enabled
again. While Marlin proceed the rest of the temperature ISR, it's now
vulnerable to a second ISR call.
