I don't think there are a whole lot of foam cutters out there period. But with my very limited knowledge of the subject, I would have thought the JA version would be better suited for it. It is possible that some of the workarounds that had to be done to make the wire cutter work with the earlier versions are no longer needed and causing problems in your new config. But I really have no idea, what the problem(s) could be.

I'm getting the impression that I'm the first one to actually try post-2.7 linuxcnc on 4-axis foam cutter hardware. I've set up 2.9-pre0 from git so I can start poking in the source code. 2.9-pre0 behaves the same way. I have verified that axis.x.pos-cmd and joint.0.pos-cmd both change as expected, but axis.y.pos-cmd changes while joint.2.pos-cmd does not. So something is broken in joint-axis code for the XY;UV geometry. -- Ralph ________________________________________ From: Ralph Stirling Sent: Wednesday, June 30, 2021 5:20 PM To: [email protected] Subject: four axis foam cutter 2.8 config I upgraded our 4-axis hotwire foam cutter to 2.8 recently, and have not been able to get it running again yet. The auto conversion doesn't seem to be quite sufficient for foam cutter configurations. I now have homing on all four axes working (XY;UV), but once homing is finished I can't jog U or V. The backplot shows motion, but the axes don't move. X and Y jog properly. The U and V (and joint 2 and 3) sections are copied directly from X/0 and Y/1 with only the axis and joint designation changing. Does anybody have a functioning 2.8 foam cutter configuration I could look at?
