Laser sculpture appears to shake wavy lines

DIY’s laser carving machine, the speed of the sculpture of more than 800mm/min, the wavy line of the jitter will appear.

in what axis do you have the waves?

Hello, XY will not shake when walking independently, such as walking a long square, but as long as XY moves at the same time, there will be wave lines.

That could be interference… Check the wires, if they’re bundled together it could be causing jitter…

Or the psu. There could be an issue with current supply. A bigger one sbould sort it.

See if the voltage drops when both motors run v single motor
