Heater will not turn on after auto tuning PID
-
The hot end heater will turn on when an auto tuning via g-code is issued. So I know my sensor and heater wiring all works okay. However it will not turn on when i put a number in the active window for the heater, regardless of what number I enter. The heater remains off.
Here is the code from my config file
; Hot End Heater H1
M301 H1 S0.7 P32.1 I1.036 D93 T0.4 W180 B30 ; Use PID
M305 P1 X202 ; Configure PT100 for heater 1 - 2nd daughter board 1st connector
M143 H1 S280 ; Set temperature limit for heater 0 to 280CHere the result of the autotune
Heater 1 model: gain 312.5, time constant 232.7, dead time 4.1, max PWM 0.70, calibration voltage 23.9, mode PID, inverted no, frequency default
Computed PID parameters for setpoint change: P32.1, I1.036, D93.0
Computed PID parameters for load change: P32Just in case here is the other config file updated by the M500 command.

You need to make the tool active before you can heat it, by sending an appropriate T command (e.g. T0) or by selecting the tool in DWC.
