Duet 2 Wifi Dual Z issue after increasing esteps

deckingman

@slabstations This is not relevant to your problem, but you have two sets of axis limit commands (M208) - one under your "drives" section, the other in "axis limits". The latter will override the former so you might want to remove the former and/or make sure that the latter matches the machine (the two set of values are different and only one can be true).

@Phaedrux I was able to get both z motors running properly and able to run the g32 command successfully. Everything seems good to go, but when I heat the bed after PID the board makes loud chrips/hums and such. Here is a link to what it sounds like https://youtube.com/shorts/MbS4bipRc7Y?feature=share I tried adding Q10 to M950 H0 and same sounds just different pitch. It was printing, but has since stopped in the middle of the print.

M950 H0 C"bedheat" T0 Q15

Is the parameter Q with the value 15 wanted? Default is Q250 for heaters.
This could cause the hissing noise when Q15 is not requested for the heater.

If Q250 is correct for the heater I would repeat the PID tuning.

slabstations

@norder I did not have the Q15 in there before and it did the same thing, I had read on a few post on the forum that it may fix it. I even set it to 250 and same noise

Norder

@slabstations
You always had the hissing, or when did it start?

Norder

Do you mean the noise that can be heard when you show the print head?

Phaedrux

You could try Q1 or Q2 even. I don't think you'll be able to totally eliminate the sound though.

Did you stop it or are you saying it stopped? Was there an error message? What exactly happened?

slabstations

@norder It starts to play a high pitch sound when the bed is being heated, besides that it seems normal. And the sound in the video that syncs up with the red light flashing on the board, not the steppers moving.

slabstations

@phaedrux I tried that too and it was still annoyingly loud, do you think it could be the power supply? I could try hooking a meanwell one up to it.

slabstations

@Phaedrux The stock one on the LulzBot Mini is a 24v 150watt, meanwell is 24v 350watts.

slabstations

@Phaedrux The bigger watt power supply seems to have fixed the chirping humming noise, and the red led for the bed heater is solid and no longer flashing!
