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

@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?
