It seems to do raster engraving fine, though I haven't tried to slow that down below 11%, so I'll have to try that. mov file that probably won't attach here. I have checked the bearings and carriages and the head moves smoothly left to right and back and forth with no play or tight areas. Most speed settings less than 10 will create this "vibration/chatter", there may be a few that didn't, but it seems sporadic. For example: If I cut a small 1" oval, the the small arcs on the left and right ends are burning deep while the top and bottom barely get marked, this is with power set at 1%! I tried many different power settings, no change. Speed set below 11% and I get a loud vibration/humming type sound (not all the time) and the cutting gets sporadic. It seems to be doing good on vector cutting if I have the speed set above 10-11%, the curves may seem a little choppy/stepped, but I don't know what it did when "new" for comparison.

I am having an odd problem with my "new to me" Epilog Summit (1996) 25 watt laser.
