Post the .c2d file, generated G-Code, step-by-step notes on how you are securing your stock and setting zero relative to it, and a photo showing an attempt at cutting still in place and we’ll do our best to look into this with you.
I am securing the stock to a custom wasteboard i made that is secured to the shapeoko wasteboard. I am using 3d printed clamps to hold the stock on corners. I zero X and Y in the lower left corner of the stock. I zero z on my custom wasteboard. I have measured the thickness of the stock with calipers an used that as my stock thickness.
I am using a whiteside 1550 60 degrees v bit i got from amazon using the #302 tool profile as it seems to match that ( besides flute length which i cant seem to change
Easy mistake to make. I think that’s probably why many people set their zero to the top of the stock rather than the bottom, particularly if you want to run the same .nc file on lots of different thicknesses of material.
