Please help me. Yesterday my Falcon 2 40w laser engraver was working fine, now today, using the same GCode file, using the same Blank Matte Black Metal Business Cards, going with just 1 pass, it is not working correctly, it making double lines. As you can see, it seems like the lasers are miss aligned. Please help, how do I fix this? See image.
I fixed it.
The Eccentric Wheel was too tight, it was loose and I tighten it up yesterday, but too much I guess, so I loosen it, and now it’s fine.
