My Trotec SP400/80 must be turning into a teenager! Recently, engraving is great but I am unable to cut through any material past about 10 inches from the left side, cutting good before that. I am not getting full cuts through solid wood or plywood (I’m aware of plywood pitfalls) even 1/8 inch Baltic birch, and in the past I was able to cut through 3/8 inch with multiple passes. I have aligned my beam and leveled my table with no luck. For settings on the 1/8, I’ve tried multiple passes at 100 power, .10 speed, to no avail. Any ideas?
