Ive aquired a fox alien 20w, and the gal thinks the mother board (control board) is shot.
Any suggestions to find a replacement?
You can test the laser with pretty much any GRBL based controller board.
First, see if LightBurn will talk to it…
There’s probably a little chip on the board that says CH340 or CH341. If that’s there, download the driver here:

If the board communicates but does not move the motors, the motor-drivers may be replaceable.
A clear close-up pic of the control board may help us make good recommendations for repair or replacement.
