Stepper suddenly losing power.
« on: May 22, 2018, 10:03:06 AM »
Hi Folks, I have a parallel port based CNC router, with slaved Y and A outputs running the gantry. I had a crash a couple of weeks ago and I am now experiencing occasional loss of power to my Y axis motor, this is bigger than a few lost steps. I will be in the middle of a cut and the motor will stop and the gantry will twist out of square and I have to e-stop and power down and then everything will work again for a while. I am wondering if the motor or driver could have been damaged by the crash or if anyone has any other ideas as to what might be causing the problem. Motors have been running flawlessly for a year previous to this.
