@dc42 @Phaedrux I appreciate the help, I rewired the whip and voila it worked. Thank you everyone for your time. I should have rewired it from the start, the config is NOT that hard!

Cheers

fans tested wiring is perfect, replaced anyway, same thing.

@Phaedrux not a bad idea to inspect wiring. Ill do that next.

@Phaedrux m106 works perfectly, except when printing. So before starting a print, m106 works, after a print ends, it works. The identical m106 commands in the gcode are ignored.

So i tested the fan on one of the always on ports, it worked perfectly. I swapped fans, no change.
I tried different duet boards as well. no change.

I did some calibration tweaks to my config recently as I switched to rails, and upgraded to 3.44. I checked the profile gcode vs code that worked in the past. I didn't see anything there.

I downgraded to 3.4, and no change.

So to your point, I think I've narrowed it down to to config or firmware.

I 'll create some small sample gcode now for a 2 layer cube, and get back to everyone.

So in the last week, my part cooling fan0 stopped working on my duet 2 wifi.

I tested the fan always on, perfect. PWM control via m106, no problem. But when actually printing, m106 is ignored. I checked the gcode, it looked fine.

In fact the part fan comes on after a print if you stick a m106 s1, in the post print, after z < 300. I mean at this point I am the holy water stage.

I thought it might have been a profile issue in Simplify3D, kiss slicer had the same problem. If anyone has a Cura profile for a duet2 equipped delta, I'd try that.

I've also swapped the board out of my cr10, no change. Tried versions 3.4 and 3.44.

I am at my wits end. Any help would be greatly appreciated.

I downgraded to 1.20, i probably confused the error, will retest 1.21 later after my printing is done.

I am getting the same error. Two prints bombed so far.

Thank you for the help

D1 is fine. Is there something I can test or replace on board?

@perolalars:

@Camalot977 Would you care to share your sys folder for the CR-10? I have been trying to use the reprap configuration tool but since I have not yet got my cr-10 4 printer I cant tell whats what…

A interested party here too my man. Excited to see this thing in action. My motor config on a late s4 is being a hassle
