Z motor blew
-
@bot - the nylon washer is under the metal one- the metal washer isn’t actually touching the board, but I do see your point.
-
@Thinepa This is why I asked a question instead of just pointing fingers. If there is a nylon washer underneath I can't see how it would be an issue, so long as there is no contact between metal and other areas.
*not actually a robot

@bearer - I was aiming to use E1, but would I still be able to use both z motors? I’m still learning (clearly), and am not sure if remapping the driver would allow me to use both z motor connections (the ones adjacent to the z motor driver) and the E1 driver, or if I could only use a single motor at E1.
-
@bot - I do appreciate that. I’ll remove the metal washers still - just in case.

the only magic there is for the z driver is that here is two headers that gives you convenient access to run two motors in series - you could replicate the same arrangement with wiring the motors in series before connecting to the single E1 header.
-
@bearer - that makes sense. Thanks!
-
but maybe find out what caused the short first so you don't end up with E1 sending smoke signals
-
@bearer - true. I’m thinking I mis-wired my z motors. Breaking out the multimeter to confirm.
-
Well - after some multimeter deciphering, I've come to understand that my z motor coils run A1 A2 B1 B2, whereas my other stepper motors run A1 B1 A2 B2. After removing all metal washers, rewiring and setting up my Z motors in series on my E1 driver, all of my axes seem to be working.
My last problem is that I keep getting an error on my Driver 2 that it's over temp. I'm certain that that chip has blown, but is there a way to "turn off" that driver so I don't continue getting that error? I can turn off the motor with M58, but that doesn't seem to affect the driver error.
Any thoughts?

Yes you can disable the driver using M569. Specifically the P and R parameters.

Specifically, the R-1 parameter.

@Phaedrux - thank you very much. Worked perfectly. No more warnings.

@dc42 - the wiki is super helpful. So much to learn. Thank you!
