Y axis issues after removing rotary

This is probably what’s going on in your situation.

Won't Frame after switching back from rotary

I’m guessing you don’t have the latest firmware installed for your laser. What’s likely happening is that Ortur for some of the lasers used a non-standard value to enable homing of $22=43. But LightBurn puts this to $22=1 when reenabling. Apparently this has been fixed on later firmwares. Try setting $22=43. Then rehome and retest. If that doesn’t work try resetting to default values by issuing in Console: $RST=* That should clear it up in most cases.
