I have a laser machine .I use it for 4 years.
... but now I have a couple of issues when doing fine engraving:
1) It doesn't return to origin. Each time it's about 1/2 a mm higher and to the right of where it started
2) it's now making (some) straight diagonal lines, jerky/stepped.... in 1/2mm steps.
I'm not sure if this is due to the controller board, or (as I suspect) belts need tightening.
Which I've never done - does anyone know how I can solve the problems?
Thanks
Belt Tightening?
