Greetings,
This is probably wishful thinking, but I have a foam cutter that's using XYAB g-code.  The XY profile shows up on the toolpath display with no problems.  The question is whether it's possible to have a second display that shows a toolpath for AB at the same time?  I haven't found any way to do this, and I suspect there probably isn't a way, but it doesn't hurt to ask.  
Thanks,
Rusty
