HELP...SSR With Heater Channel on 3CH daughterboard

@alex-cr Ahhhhh that makes sense, I will do that in the morning. I think that would have to be it, didn't even think of that. I'll report back tomorrow with hopefully good results!

@dc42 thank you, that clears it up!
-
@dc42 So got the thermisters remapped, the SSR kicks on and started heating the bed up, then it just faulted again after heating the bed from 18C to 30C. Only stays on for about 30-45 seconds. Thoughts?
-
Have you performed an M303 command to get the heating model updated?
BTW you may have to do this manually depending on what firmware version you are currently running.
-
@alex-cr ok what if it is for bang-bang mode? So I have to tune the bed before it will heat all the way up?
-
PID tuning is recommended so that the firmware has an idea of the heaters performance (heat up and cool down time). In bang-bang it can be too slow for the default watchdog and it times out.
-
@phaedrux understood, so for an enclosure heater, is there a way to adjust the "watchdog" parameters? I don't know how long it will take to heat my enclosure and I don't want it to time out.

Yes, PID tune the heater.

@phaedrux ok
