Hey G'day people,

Mate of mine called me earlier today and I really don't know how to guide him.

He has built his own cnc, he helped me build mine. He seems to have an issue with vibration from the steppers.

Only thing is the vibration only occurs when running Gcode.

Manually running x y z up down left right, steppers have a sweet sound.

Run some Gcode and they sound angry, grinding vibrations.

Any guidance as to what to look for, I haven't got a clue where to start.

He has 4 power supplies 60 watt

Wantai DQ860MA driver

Wantai stepper 85BYGH450C-012B

So far he has been going up and down with stepper calibrating doing lots of things so now hes lost ....

Any suggestions? or recommendation on settings.

He's using UCCNC and a UC100

Cheers,
Steve
