General Mach Discussion / 4 axis CNC Foam Cutter Issue
« on: September 12, 2014, 02:01:59 AM »
I am running the latest version of Mach3 with a 4 axis CNC foam cutter. I am cutting tapered foam wings using Profil2 to generate the code.
When I cut a tapered panel such that the larger end is to the left (x/y axis), everything goes smoothly. All four axis respond smoothly.
When cut the same panel with the large end to the right (A/B), then I run into issues. During this cut, the right horizontal axis will suddenly accelerate to large values and then return to the ordered 6 ipm feedrate. It will happen several times during the cut. If I turn Constant Velocity off, the problem disappears.
Has anyone else seen this behavior or knows of a solution?
Cheers,
Adrian
