I have used the Vcarve DXF prost processor where we have layered the drawings with the layer names coded with a T=thickness of material and P=dePth of cut.
If necessary we can also tweak the files for quicker CNC set up by extending housing, adding wedges etc. For this we will need more information on the CNC setup of your supplier.
New to the forum, so I’m not sure if this is where I post a new stair I’m working on and need the DXF file to send to my CNC guy who has a SCM machine.
Trying this approach before I buy the full program.
