Is there thermal paste or additional solder point under the driver chip ??

Hello
I got similar problem with x axis, moreover my driver got fried. The problem was in motor wiring. One of the wires was crimped to much and got broken under insulation. The first thought was the motor problem because during X homing motor was shaking (short moves forward and backward) and "Error: short to ground driver 0" after second attempt to homing driver got fried. I checked wires and one of them was cut under insulation. Made new wire and remaped X motor to driver 5 and it runs with no problems. If one of the motor wires was cut why there was "Short to ground error"??? I am willing to replace fried TMC driver.

@dc42 can You provide me some advice in replacing fried driver.

As advice for anyone making own wires. Do not crimp terminal around insulation too strongly. The terminal blades may damage wire and always check wires with multi-meter. RUSH is Your greatest enemy.

Re: Choice of TMC2660

Is it hard to replace fried driver on DuetWifi 1.02 board. I have two spare TMC2660 chips and. Soldering is not the problem for me. Does the TMC2660 requires additional config or flashing after soldering to Duet PCB board ??

Why You are using deploy and retract probe gcodes (M401 and m402) instead of M280.
Web configurator creates retractprobe.g and deployprobe.g wit M280 inside not M401 and M402 ??
