Ive creaed a grid pattern for the spoil board but when i run it the first contact goes all the way to the bottom and stops. ive tried all different depths, mm and inch but same results.
Where do you have the origin set in the file?
How are you setting origin relative to the stock?
Post your .c2d file, generated G-code, step-by-step notes on how you are setting zero and managing all tool changes and photos or a video show how you are setting zero?
