Hi there,
I just started using Cambam and it is my first experience with a cnc milling machine. I built my own one and I am using Mach3.
I have already experienced some machining with simple parts and some engraving, now I am trying to machine a 3d part and I have set Cambam as per pictures here below. Sorry if the pictures appear rotated 90° but I am unable to post them straight.

The result I am having looks quite messy, despite the fact hat I have set depth increment 0.5 mm I see the tool going quite deep (7 mm) since the beginning. I do not understand why?

Moreover I would like the part to be machined layer by layer (0.5 mm each) with the router scanning the part left to right and back and not left to right than lift back and start again.

I would appreciate help and hints on how to achieve the above and solve the depth issues.

Thanks in advance
