Need Help!- Understanding the zero points software vs my solsylva.

[czwalga]

Alright my solsyva isn't completed yet, but i've had some time to play around with cad/cambam.

I've yet to interface to mach3 or anything of the sort.



So I've imported a small dxf into cambam, made the necessary pockets and drillings. My question is my drill points start at 0, and go to -.30

My question is how does the CNC software know exactly where the zero point is, it's going to depend on the tool and thickness of the wood. I've read a lot of tutorials but I havent seen this covered anywhere.

Either you jog the tool down to the surface of the wood, and manually zero the Z axis at that point using the onscreen button, or wire up an auto zero plate and use an auto zero macro to do it. Read through this:
