I had a print come out weird, where one piece had a gap in a continuous line (the start and end didn’t line up), and there were some overlapping shapes that shouldn’t have been overlapping. I thought it was a fluke so I power cycled the machine and tried again with the same results.
I was watching closely the second time and the laser cut the two triangular pieces on the left just fine. Then it started the cross pieces with the topmost one and when the beam got to the top-right corner there was a grinding sound and then the beam seemed to be half an inch off for the rest of the print, overlapping into space it shouldn’t be cutting. I checked my svg and the vector path is clean - no crazy cvs or anything.
