Help! My tinyg quits when I turn on my r7 quiet spindle. Everything works fine until I turn the spindle on then my pc loses connection to the tinyg until I turn the spindle off again. I’ve tried relocating the spindle, new wires, and putting the spindle on a seperate power supply with no luck.

I’m controlling the spindle manually, not though the tinyg.

I assume you’re using shielded wires for the stepper motor cables? If you aren’t I’d advise it, while some seem to get away with it, others have issues like you have described. You will have to ground the shielding in the cables to the common ground. You should also pass through the power lines for the spindle through the big iron ring that should have come in your pack, that will help isolate the noise from the spindle.
