not for nothing, I don’t use ANY of the “normal” software with my x-carve. i use HeeksCad to Generate 3D models and create my g-code. I use Universal G-code Sender to send that g-code… I’ve done some pretty dang intricate work with almost no problems…
Have you tried a different g-code creator? (I don’t know if that is a pre-processor or a food-processor - i don;t care about the vernacular, I just make stuff)
WOULD YOU LIKE TO install Universal G-code sender and I’ll send you the g-code for a circle of whatever diameter you wish?
but from all you’ve said, I think it is a software problem (or your hardware is having a tough time sending the info to the motors)
Im using UGS. Can i send you the code and you run it? Its a simple .636 hole. Im trying to rule out everything, but everything is run through USG, grbl, and arduino. Ive tried a different computer without Vcarve installed but still the same outcome.
I know its not mechanical im 100% sure now.I spent 6 hours today taking it apart, checking everything for tightness, level, square, plum, wires, belts are all exactly the same tension.
