I am getting a weird double engrave in the center of my workspace. After reading a lot of posts here where folks were having similar issues, I was able to make a huge improvement after finding a very loose belt. Seems to be dialed in now except for approximately 1 inch at the very center of my machine.
Which tells you another mechanical problem happens right about there. Check for things like a dragging cable, snagged air line, loose / damaged guide rollers, and basically anything that’s either too tight or too loose.
This test pattern can identify mechanical problems:
Scale it uniformly to fit the platform and run it as fast as it will go in Line mode with optimizations turned off and power set to mark a sheet of cardboard. Any differences from the design will be informative; a photo will let us look over your shoulder.
Thank you! I’ll try this test today. I didn’t realize over tightening could be part of the issue. I’ll back off a bit to test that as well as the file and will report back.
