HELP...SSR With Heater Channel on 3CH daughterboard
-
Post your config.g file. If you run M98 P"config.g" do you get any errors?
I just had a bad experience with ignoring the errors coming out of it because I thought I knew better, cost me a couple days...
-
@alex-cr I think your on to something, this makes sens sensor #0 and 3 not being configured, I was too ignoring them
What do I need to do to fix it?; Configuration file for Duet 3 (firmware version 3)

M950 H0 C"1.out1" T0 ; create bed heater output on 1.out1 and map it to sensor 0I think the problem might be that your temp sensor for this heater is defined as being plugged into the 6HC while your output is set on the 3HC.
Is this supposed to be the case?
Edit: I just read down further, can you move your coolant sensors over to the main board and your control thermistors over to the 3HC?I believe the firmware requires that temperature sensors that control heaters be plugged into the same board. It will need to be confirmed though.
if your temp sensor is actually plugged into temp0 on the 3HC try changing the P command to the following:
P"1.temp0"By the way it looks like a similar change will be needed for your chamber heater on H3.
Edit: I just read down further, can you move your coolant sensors over to the main board and your heater control thermistors for H0 and H3 over to the 3HC?

@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
