@bot - the nylon washer is under the metal one- the metal washer isn’t actually touching the board, but I do see your point.

Perfect. I didn’t want to solder in a new chip only to have to remove it, flash, then replace.
Much appreciated!

After a wiring mistake, I released some magic smoke (and sparks) from my z stepper motor driver. I was able to re-map the driver, and the board is again functional for me, but I would like to regain full utility in the diet WiFi, so I purchased a new TMC2660 driver chip. Before I solder the new chip on, I am wondering if anyone has information on how I’d go about re-flashing the driver? Would it automatically flash when I install the firmware, or is there a separate procedure?
Thanks in advance!

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

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

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?

@bearer - true. I’m thinking I mis-wired my z motors. Breaking out the multimeter to confirm.

@bearer - that makes sense. Thanks!

@bot - I do appreciate that. I’ll remove the metal washers still - just in case.

@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.
