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?
