I’ve had this cutter for a few years, and it’s worked off and on for me. Right now the cutter will start off ok, but slowly start cutting squished on the x axis. Any Ideas? It was cutting fine last year, then turned it on and it’s doing this now.
Probably your Z-axis belt needs to be re-tensioned or replaced.
The Z affects the Y?
SOMETIMES: All the cuts are stepping to the left and down like backwards stairs.
OR: It’s squishing X axis
OR: it’s just fine.
All these without any adjustments to the machine.
Please check your belt tension, and check your belts for damage — make sure that your pulley set screws are in place and tight ( http://docs.carbide3d.com/shapeoko-faq/shapeoko-3-how-to-check-the-pulley-set-screws/ ) also check the eccentrics: http://docs.carbide3d.com/support/tensioning-eccentrics/
Copy that. I’m on it.
I had a similar issue, I was loosing steps on the Z this lead me to loose steps on the X/Y because Z got caught. I’d be all over that Z belt.
