notes:
|
|
- This command may block the command queue. Enable `EMERGENCY_PARSER` so that hosts can break in using [`M108`](/docs/gcode/M108.html).
|
|
- Use [`M143`](/docs/gcode/M143.html) to set the cooler temperature and proceed without waiting.
|
|
- Configuration settings.
|
|
- '`COOLER_MINTEMP` Provides a low end safe operating temperature, cannot be lower than 1°C. CO2 lasers tubes can be damaged with values less than 15°C.'
|
|
- '`COOLER_MAXTEMP` Provides a high end safe operating temperature, when breached the system will shutdown if `THERMAL_PROTECTION_COOLER` is defined. CO2 laser tube life degrades exponentially at temperatures above 24°C.'
|
|
- '`COOLER_DEFAULT_TEMP` LCD menu default value is 16°C.'
|
|
- '`TEMP_COOLER_HYSTERESIS` The accepatble temperature variance + or - to the target.'
|
|
- '`COOLER_PIN` Cooler on/off pin used to control power to the cooling element.'
|
|
- '`COOLER_INVERTING` Inverts the on value to 0.'
|
|
- '`TEMP_COOLER_PIN` Laser/Cooler temperature sensor pin.'
|
|
- '`COOLER_FAN` Enables a fan on the cooler.'
|
|
- '`COOLER_FAN_INDEX` Defines which fan to use 0,1,2 etc.'
|
|
- '`COOLER_FAN_BASE` Base cooler fan PWM (0-255); on when the cooler is enabled.'
|
|
- '`COOLER_FAN_FACTOR` PWM increase per °C above target.'
|
|
- '`THERMAL_PROTECTION_COOLER` Enables thermal shutdown protection.'
|
|
- '`THERMAL_PROTECTION_COOLER_PERIOD` Thermal protection check interval in seconds.'
|
|
- '`THERMAL_PROTECTION_COOLER_HYSTERESIS` Thermal variance +- limits check interval.'
|
|
- '`WATCH_COOLER_TEMP_PERIOD` Check interval in seconds before runaway condition shutdown.'
|
|
- '`WATCH_COOLER_TEMP_INCREASE` Allowable increase during check interval.'

`M193` optionally sets the cooler target temperature and dwells until the cooler temperature is equal to or below the target.
|
|
Any value greater than the COOLER_MAXTEMP (set in Configuratin_adv.h) will be set to the COOLER_MAXTEMP value.
|
|
Use [`M143`](/docs/gcode/M143.html) if you want to set the target temperature without waiting or to turn the cooler off.
