@dc42 thank you so much for the support! I really appreciate it

@dc42 I connected the EZ-Switch that the berdair comes with to an unused heater block + a fan header -- This appears to have solved the crashing issues.

Using any high PWM frequency after this ended up resulting in "all or nothing" fan control -- i dropped the frequency down to 20hz and that seems to have solved the issue, though.

@dc42 just got another crash -- should i have the berdair wired differently than i do now?

@dc42 the Berdair is connected directly to FAN0 -- i was under the impression that a flyback diode had been included on all the fan headers in recent board revisions - i might have misunderstood?

@hackinistrator haven't had a bunch of time, but i've run 3 dry runs so far with no issue - a pretty good sign.

@hackinistrator Moved the board over and repositioned the berdair to be nowhere near the board... we shall see.

Anotha one.

@dc42 Will do dry-runs throughout today. It's weird, sometimes it completes a print just fine, sometimes it fails -- but all with the same file.

@Veti

@Phaedrux no dice, another crash. @dc42 any ideas?

I see that 4.2 was just released so i'll update to that and try again.

@Phaedrux ah, ty! gonna let this print finish on beta 4, then will update to 4.1

@Phaedrux just upgraded, will do a few test prints! We shall see...

@markz I'm not using "EZ-Switch" board that was packaged with the berd-air, so both lines are hooked up to the fan header -- as best as i could tell before installing, this was fine, since the fan headers have flybacks wired into them

@markz
Resistance on my heated bed (measured at connector on board) is 3.3ohms, it's a 24v bed, so that would be a ~175watt bed, correct? I'm using a Mean Well 24v 350w PSU and my hotend is 50w, so i should have plenty of extra room, wattage wise, right?

24v to the pump is over a fan header on the board (AFAIK newer duets have the flyback diode on all fan inputs internally), I'm not sure how to diagnose if i have noise on the 24v line.

and another one just now, the more the merrier, i guess

Good call! Attached is the zipped gcode file, renamed to .txt:

vibrationDampener2.gcode.txt

@Phaedrux
Another crash from this morning (berd air still connected)

The gcode file is too large to attach here -- is there a preferred hosting site for me to upload the file?
