Me thinks there is a disconnect here somewhere...... EMC can handle 4 or even 6 axis coordinated motion just fine. It does not care if there are 2 parallel X axes and 2 parallel Y axes. If the code can be generated with 4 axis coordinates for each move command EMC can process it. Yes there may be some naming convention issues for the axes, but that can be overcome.
The issue is that the foam cutting community is locked into design/CAM programs that insist on also being the machine controller so there is no way to get the G code in the first place. BobCAD and Vector both offer 4 axis wire EDM support. Could someone look into generating some output to see what it actually looks like?
