Re: After Firmware update on Duet 2 Ethernet from 2.04 to 3 Error
Searched pulled up little in the way of this issue but the above-linked thread seemed very close to my situation. unfortunately, it didn't help any.
I've tried running the PID autotune on both the hotend and the bed. The hotend rockets to temp then holds it strong; only in error by .8 max in either direction.
The bed, however, crawls from room temp (25ish is what the sensor is reading when -cold-) to about 28c before it throws the "temperature rising much more slowly than the expected" fault.
These are my heater settings in config.g;
M308 S0 P"bedtemp" Y"thermistor" T100000 B4138 ; configure sensor 0 as thermistor on pin bedtemp
M950 H0 C"bedheat" T0 ; create bed heater output on bedheat and map it to sensor 0
M307 H0 B0 S1.00 ; disable bang-bang mode for the bed heater and set PWM limit
M140 H0 ; map heated bed to heater 0
M143 H0 S120 ; set temperature limit for heater 0 to 120C
M308 S1 P"e0temp" Y"thermistor" T100000 B4138 ; configure sensor 1 as thermistor on pin e0temp
M950 H1 C"e0heat" T1 ; create nozzle heater output on e0heat and map it to sensor 1
M307 H1 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit
M301 H0 S1.00 P209.7 I17.817 D970.2 T0.4 W180 B30 ; Use PID on bed heater (may require further tuning)

I'm not sure what the heck is going on, M140 proceeds the other stuff. What could I be doing wrong in trying to make this printer operate as designed?
The printer - Tevo Little Monster with all OE hardware and PSU, minus the steppers (0.9 NEMAs), dual drive extruder and Duet2 WiFi (obviously).
