Continuing the discussion from X, y, and z motors not responding: i am getting only 2.9v out of my power supply from each b&w wire set and a low buzzing sound is coming from the power supply box.
It should be 36 volts. Try turning the adjusting pot near the wire connection. Sometimes, it vibrates out of adjustment. It’s a touchy little devil

screw didn’t affect voltage output. same reading with 220 input. definitely the power supply.
They are pretty cheap. Good luck
thank you. should be under warranty. I’ve only used the table 3 or 4 times.

Glad you figured it out!
In the future, you don’t need to start a new topic as your issue changes, you can simply edit your topic heading by clicking on the pencil next to it. It makes it easier for others to know what has already been said and done. No worries, though.
