New here, I bought a shapeoko3xl to help with guitar building, and I’m having some weird accuracy issues on the x-axis. The inside dimension of the pockets on the x-axis comes out perfect (like .0005"), but every other dimension (such as the distance between pockets, and the outer contours) on the x-axis comes out larger then it should. I’m using fusion 360 for design and CAM, the carbide3d post process, and carbide3d to run the shapeoko. Stock to leave is set for 0. Not really sure whats going on here, so any help would be much appreciated.
Assuming all is mechanically well (tight belts, stepper grub screws down, etc), start eliminating software variables:
Try a very simple circle and square cut and see if you can measure any inaccuracy in those. Should help riddle out whether there is an issue in the cad, cam or machine.
sounds like a tool path problem to me, inside “pocket” cut exact, outside cuts wrong. I am no expert by any means, but make sure you have the right type of cut on your tool path. If I’m wrong, don’t worry about it, the only time I’ve ever been wrong is when I thought I was wrong but was actually all right, of course we are all half left, so “grains” of salt required.
