Replacement controller for cnc 3018

Can anyone recommend a decent controller card replacement for my cnc 3018 to drive a laser.

I think I have issues burning images with current controller. Seems to do fonts. But loosing detail on images.



Honestly, I would suspect the laser module more, though it’s really hard to say for certain. Are you sure that you’re in proper focus?

I will check focus. Other stuff appears fine


I dont suppose there is some test page I can burn, to check laser power?

I’ll make one. Can’t be too hard
