ok, i know this was probably asked a million times, but here it is again. can i cut 2,5D or 3D in kcam? i am close to finishing my little desktop machine, and the first things i will be making are improved bearing mounts, stepper mounts... obviously, this has to be done out of thicker material (let's say up to 40mm). can i cut it with kcam? i got a hang of the most of the kcam setup, but when i import a block with a central hole in dxf, all i get are lines, as if it's engraving in air, so to speak.
any tips or tricks?
