I am having problems engraving circles with my Laser Axe laser engraver. I have checked all mechanicals and all seems fine.
There are 2 pictures of board testing attached. The 1st shows the problem I am having. I loaded the drawings using Gcode. The 2nd shows a test with a circle within a square. For some reason the program will not load a Gcode with just a circle. This seemed to work fine. The 2nd square with 3 circles was loaded from a jpg file. It also seems fine. Thinking that the problem is with the controller, I changed out the controller with a different GBRL 3-axis controller with the same results. So not the controller.
Anyone have any ideas what to next?


hi, assemble problem, you should tight the belt, then the circle will be ok.
