Solved Duet mini+ failing to heat hotend
-
Can you use M500 to save the PID results and then post your config-override.g so we can see what values it has saved?
What command are you using to PID tune?
-
M303 T0 S205 is what I'm using for the hotend.
I wiped the override, ran another PID, saved the values in config file, restarted the board, then did a M500.

You must send M500 immediately after the PID tuning completed, not after restarting the board.

I'll try that. One moment
(Sorry about the weirdness on the post above. I was trying to upload all the files and it marked it as spam and won't let me edit it anymore)

It probably didn't like the bin file either.
-
Tuning complete and M500 put in right after. I'll let it cool off and try again.
I enabled M929 as well to see if it catches anything. If nothing shows, and if it's still happening, I'll put it into debugging (M111) and see if I can catch what's happening.
Thank you so much for your help so far! Very much appreciated!
I'll post when I have new results

Heater still faulting. Event log not giving any info. I'll hardwire into it and run debugging to see if I can catch anything.
Only other thing I can think of is the board is bad somehow or it's an issue with 3.3. If I can't catch anything hooked directly in I'll try to downgrade everything to 3.2.2

Downgraded to 3.2.2, same thing.
Ran debugging to USB with all settings enabled, nothing shows up when it faults

M563 P0 S"Hemera" D0 H1 F0:2
Are fans 0 and 2 both part cooling fans? Your fan definition says that fan2 is a cpu fan. So maybe you should change F0:2 to just F0.
Can you try tuning the hotend with M303 H1 S205 instead of T0?
@nightlonk42 said in Duet mini+ failing to heat hotend:
Supply voltage: min 27.9, current 28.0, max 28.1,
Also I think you may be over volting your heaters

Made the CPU fan change, lowered voltage back down to 24v and testing again using H1.
Will update with results

That did it! I'm not sure if it was the CPU fan setting or running it with H1 but it's working as expected now.
Thank you so much! This was driving me crazy for days now!!!
