IMG_3017.jpgI have a 50 watt Chinese laser. Not long ago we had a power spike, took out all our florescent lights and multi strips, blew the fuse in my laser and I ended up putting in a new tube and power supply...it's like 50% better than when new. BUT, not long after replacing supply and tube i noticed when I did multiples on an X axis, the layers as it got away from the origin...mis-aligned. My wife suggested I try the Y axis, and that worked, for about 2 weeks...Now either way the layers become misaligned as it gets away from the origin...BUT in some cases the first and last multiple, will be aligned. Belts are tight....This makes no sense to me, it was a gradual decline.... What the Heck. It doesn't seem like a stepper motor thing because it is so consistent, and on longer multiples the first and last will be aligned. The picture shows one done on the X axis, and one done on both. There are 3 layers, the bee design (raster) and holes (vector) and cut out circle on the outside (raster). Do any of you Experts have any ideas about this?
