"Tuning with fan off", But fans are on?
Hello fellow tiny hot glue gun masters, I'm in need of assistance.
When I run the auto tune on my bed, It never makes it past the step "Auto tune starting phase 4, tuning with fan off"
I have waited over 1.5 hours. Strangely the fans are on so maybe the tuner has a "Fan off" command is not making it to the part cooling fans? they are controllable in the Dashboard so I know they work. They are pugged in connector marked FAN0 on the board. I burnt out FAN1 & FAN2 thanks to barrel connectors being easily shorted (never again). The hot end fan is connected to the always on port. the VIN pin is getting a 12v source in. M303 worked with the Hotend and I saved with M500. I attempted to manually input the information in to the .config by adding the line "M307 H0 A2.429, C140.0, D5.5, S.5 " in the Heaters section after reading it in the "M307 H0". output.
Board: Duet 2 WiFi (2WiFi)
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.4.0beta2 (2021-08-03)
Duet WiFi Server Version: 1.24
Duet Web Control 3.3.0
Heater 0 model: heating rate 2.429, cooling time constant 140.0, dead time 5.50, max PWM 1.00, calibration voltage 0.0, mode PID
Computed PID parameters: setpoint change: P13.4, I0.482, D51.4, load change: P13.4, I0.949, D51.4
I'm sure its something obvious I'm doing wrong. would love some advice of idea.

when attempting a print I get the following error. "Error: Heater 0 fault: temperature rising much more slowly than the expected 1.3°C/sec
Error: Can't activate heater 0 while in fault state
T0:40.1 /245.0 B:43.5 /0.0
after 2.5 hours of tuning I got the following error "Warning: heater behaviour was not consistent during tuning
Warning: Auto tune of heater 0 failed due to bad curve fit (R=0.173, 1/C=-0.0372:-0.0372, D=9.9)"
Can you please post the results of sending M122 and M98 P"config.g"?
Also please post your full config.g and a description of the details of your bed heater.
What M303 command did you use to tune the bed?
