After finishing wiring my Smoothie Board to my printer, I wanted to test a part of my start gcode:
G21, G90, M107, G1 Z10 F300. I copied down these commands from my slicer which I now realize has a typo (the line
G1 Z10 F300 was missing the F). So I think I gave it this command:
G1 Z10 300 by accident. After giving it this GCODE, the x-axis motor driver caught on fire for a second before I unplugged everything. I’m not sure what caused it to catch on fire (whether it was misspelled gcode or if when I moved the x-axis by hand earlier, the motor created too much current for the driver).
This is what the damage looks like: https://drive.google.com/file/d/1OSRuQsyVXlTY3b7HdIXgItH59164hM3R/view?usp=sharing
Here is my config: https://pastebin.com/17ExNAHy
Another thing worth mentioning is that this is my second smoothieboard that has had a driver catch on fire (the first one happened randomly when I started a print, also my first smoothieboard ran perfectly well for almost a year.)
Two questions: Why do you think my drivers keep burning out? Will the board still work if I replace the driver?
