M141: Set Chamber Temperature (Fast) or Configure Chamber Heater
- Pnnn (RRF 2.03 and later only) Chamber heater index, default 0
- Hnnn Heater number
- Snnn Active/Target temperature
- Rnnn Standby temperature
- M141 S30
- M141 H3
The first example sets the temperature of the chamber to 30oC and return control to the host immediately (i.e. before that temperature has been reached by the chamber).
The second example specifies that chamber heater 0 uses heater 3.
M141 commands with H parameters would normally be used only in the config.g file.
In RRF3 a M141 command with H parameter (other than H-1) must come after the M950 command that creates that heater, and before any M143 command that sets a temperature limit for that heater.
