Newbie alert! Built a 4axis for cutting wings, but struggling with setting up feed rates. All axes work perfectly in direction and speed when operated independently (G01). I have XY set up on my left, and AB set up on my right. My problem is when I operate X and A (both parallel to each other, front to back). When I cut with G01, the feed rate is slower than when I run X or A independently under G01. I suspect that somehow the software thinks the X and A axes are at right angles to each other and is slowing down each axis to get the resultant vector feed rate??? How do I tell the software (mach3) which axes are parallel (and don't need vector compensation for feed rate), and which axes are at right angles (X and Y, A and B) where vector federate compensation is needed.
