Error whilst autotuning PID for high temperature printing
I've upgraged my printer to be able to print high temperature materials, and I'm looking to set PID values for these new temperatures.
When I try to autotune at 330°C, I get an overshoot of approximately 25°C. At this point, I get an error, and the autotune sequence is aborted. To try and counter this, I changed the PID_CONTROL_RANGE value in Configuration.h to 30. This hasn't made a difference though. Is this max temperature overshoot hard coded somewhere else?
I'm aware that I can reduce the overshoot by reducing the max pwm output, but it currently takes 10 minutes to heat to 330°C, and even longer to 400°C, so I'd like to avoid it if possible.
Any help would be appreciated. Thanks!
