Hi folks. Got my Nomad on Thursday and found it amazing looking. Screw feeds for all directions and it should be very accurate. I want to have some success before I demo it for my high school students. However, I tried my first 1/8" Aluminum part and the spindle stopped running before the part finished.
It was about noon (California time) when I wrote support on Friday, but haven’t heard back. The spindle just stutters (moves in tiny jerks), but does not rotate. In brushed motors, this would be a problem with the motor controller, but the failure behaviors of brush-less motors are new to me. In brushed motors you just need to crank up the current in the motor controller. The software is definitely feeding it power, but why it would run for 5 minutes doing a good job, then twitch around like a dead fish??? I have had an XCarve (a Shapeoko variant) for 6 years and rebuilt my machine, so I am not completely a newbie. Anybody got a quick fix or any other ideas? I am really worried that I have a very nice boat anchor right now.
