PID tuning Toolboard Extruder heater with 24V Duet 3
So I know PID tuning on the toolboard isn't supported yet. So everything says just hook it up to the main board, Duet 3 in my case, to do the PID tuning. Well my main board is 24V but the toolboard is only 12V so the heater is 12V.
So without even thinking about that I went ahead and hooked the heater up to the Duet 3 OUT1 and did the PID tune.....then I realized that I did that with a 12V heater.
So now my question, am I really supposed to hook up a 12V power supply, all mine are 24V, to my printer just to get the heater tuned?
Is there any workaround? Is the PID I just ran any good?
I had moved my PID parameters over from when it was on the duet 2 and prior to RRF3 but I was starting to see heater faults, which would shut off power to the heater, when printing with PLA. So now I'm not sure what to do next.
Thanks for any help.
It is supported in the 3.3 beta 2
Update the mainboard and toolboard.
Thanks, I'm running 3.2.2 now so what files do I need to download? I'm used to just getting the zip every time but there is no zip. No SBC
Is that it?
Yes the beta releases don't have a full zip file package. But those files should do it for you I think. If it doesn't automatically install upon upload you can send M997 to initiate the update for the mainboard and M997 B1 for the tool board (assuming it's your first expansion board).
Use M122 and M122 B1 to check the update was applied.
