I’m still insanely new to my mpcnc router. I’ve only gotten to using it a hand full of times, but over the weekend I had something really strange happen to me. During a project, it seems my x-axis stopped working. Being semi-technical minded, it seems like the driver shut itself off like it was over-heating, but that is really strange to me because I have my mpcnc in an uninsulated, michigan garage. The ambient temp couldn’t have been over 30F. I have heatsinks on the drivers chips, and I have a 120mm computer fan pointed at them too, so over-heating doesn’t seem likely.
So here’s what happened, halfway through my project, the x-axis seems to have stopped responding. I touch the stepper motors, and they’re cool to the touch, while the rest are warm, and then I check if they’re holding their position, but I’m able to spin them freely as if they were unpowered. At that point, I cancel the project and cut power to the arduino/ramps board for a minute before powering it back up and connecting with repetier host, and I’m able to use the manual controls and the x-axis is responding fine.
It’s weird, because it seems like the x-axis driver shut off on me for some reason, but I can’t figure out why it would have done that. Does anyone have any thoughts on what might have caused this or how I might help keeping it from happening in the future?
For some background info… Nothing appeared damaged. All the wires were connected. I don’t believe I’m dealing with damaged hardware or poorly constructed hardware simply because after powering it all down for a minute, things were back to working like normal.
