Error: Heater 0 fault: temperature rising
-
Hello all, I just upgraded my duet 2 maestro from firmware 2.0 to 3.1. I used the need reprap on-line configuratior. I finally got everything working except the hot bed, it turns on and I get this error "Error: Heater 0 fault: temperature rising much more slowly than the expected 1.7c/sec". Everything was working great with firmware 2.0, but now I just get this fault. I am not sure what is going on, my hot end works great. Here is the output from my config file.

Have you tried PID tuning the bed heater yet?

@Phaedrux said in Error: Heater 0 fault: temperature rising:
PID tuning
Thanks for the input, everything is working now.
