Bed fault to heat after installing RRF3 ( SOLVED)
zabana last edited by zabana
I have a machine with a COREXYUV configuration. It all was working properly with RRF2 but after upgrading to RRF3 I have in my bed the "Heating fault on heater 1, temperature rising much more slowly than the expected" error.
Here are my new config.g and the old one so I hope you guys can help me.
Thanks in advance!

Have you PID tuned all heaters? I also had heater faults after updating to RRF3 but all is OK now after tuning.
@DaveA no, I didn't. Actually I set up bang for bed and PID for hotend but I will try tomorrow to use PID for bed just in case.
It seems with RRF3 that the bed is slower than the fw wants so unlikely as RRF2 it give the fault.

Pid tuning is a good idea.
I also notice some parameters on the bed heater that did not come across from your RRF2 config. Consider changing your M308 for the bed sensor from:
M308 S0 P"bedtemp" Y"thermistor" ; configure sensor 0 as thermistor on pin bedtemp
M308 S0 P"bedtemp" Y"thermistor" T100000 B4725 R4700 ; configure sensor 0 as thermistor on pin bedtemp
@Danal the PID seems to fix the problem and the bed was heated normally 😊
Regarding the missed values in the first rrf3 config was there but tried without them just in case, they are now restored.
Thanks for your help!!!

@zabana It may not be fixed. If the fault was indeed as per your OP ("Heating fault on heater 1, temperature rising much more slowly than the expected" error), that refers to heater 1 which is your hot end heater, not the bed heater. So you may have an intermittent fault on your hot end heater - possible a bad crimp or some such?
@deckingman in fact it was the bed because I was testing separately all element,endstops and axes after the firmware upgrade before to do any print. When the hotend was tested it worked as always and expected 😊
