Hello all,
I am so close to finishing my cnc build, I can just taste it….
Here is my problem statement:
The stepper motors have a high pitch squeal when not moving, and when directed to move they barely do with a clicking sound.
Back-story:
I have been working on this build for about a year now. The power supply that I had was a switching 24V 12.5A power supply. When I was using this power supply to move the three axis they would move but only at low speeds and with no resistance. (< 60ipm) Even then they would occasionally stall. So I purchased another one of the same supplies and hooked them up in series.
As shown here. Now I get the squeal/whine and no movement. If I scale down the voltage the whine goes away but still no movement. Any ideas what could be the problem? Thanks so much for your help. I have the machine completely built and I am just aching to see it work.
