To clarify, I only used the X axis motor, I know it works and is wired up to a 4 pin connector. I hadn't yet wired the Y-axis to a connector so I used the X-axis motor. The motors are not the issue, this much I know.

@dc42:

I guess another possibility is that another component attached to the TMC driver is burned out, such as one of the current sense resistors. But I expect you would have noticed that.

Is it possible it's burnt but not visually noticeable? Would that cause the driver to self destruct?

I tested the board by

1. powered on the board to test X and Z axis motors (Y axis is the driver in question)

2. Verified X and Z functioned.

3. Cut power to the Power Supply, waited until all lights were off.

4. Hooked the X axis motor to the Y axis, due to the first driver being killed via shorting a wire I placed the wires in connectors to eliminate shorting. Also visually checked the wires were not going to short.

5. Clicked "Move right 1 mm"

6. Experienced the scent of burning silicon and dying a little inside.

Just in case, how could I map the Y axis to an extruder driver?

After dealing with a loose wire burning my original Y-axis driver, I ordered a new one from Digi-Key and soldered it back on to the board. the soldering was fine, but as soon as I clicked "move" it fried. What could cause this? Both drivers are TMC2660-PA. The Original drivers are TMC2660-PA followed by "1612 07005" while my burnt Y-axis is a TMC2660-PA "–-6 06814" (The three missing digits are burnt) I couldn't find anything other than a TMC2660-PA driver, no variants leading me to believe it's some sort of date or batch code. But I also hope I bought a driver designed for 5 or 12 volts as opposed to 24V-30V like the standard Duet Wifi drivers.

Thanks in advance!

Not as glad as I am!

I removed the burnt Y-axis driver, your assumption was correct, the other axes moved upon command looks like I'm only out $7!

So I'm only out a single IC? From what I've seen they're about $7 USD a piece. I have access to micro soldering equipment on campus, If I decide I don't feel comfortable doing it, I have friends who do work on micro satellites/Cubesats. I would really like your opinion and advice more than anything. So If you tell me just to replace a single driver that's what I'll do. Thanks for your input!

Just tested the board again, no movement on any axis whatsoever. I can, however trick the board into thinking the axes are homed by pressing the switches. I'm reading 24.11V across the Vin terminal. Accourding to the M122 command it's reading 24.6V. I am in the U.S. should I just search by username?

While running some tests with my Duet Wifi A jumper cable on the Y-Axis motor came loose and caused a short. I can tell the Y motor Driver is bad, after disconnecting everything for the night and coming back today I can't move the Z or X axis motors. No motion what so ever. Is there an SMD fuse I need to replace as well? Please tell me I'm not out another $150.

Thanks in advance!

I've got my board scanning and scanning and I can't even find an open network. let alone one with a simple password.
