Hi Jeff, I would have replied earlier but I blew up my X11 settings and it took me this long to get it working again...

Is there any way to trick the motion planner into thinking the machine has infinite acceleration during synchronized cutting?

Hmm, interesting idea. Not too bad for a simple circular cam but unfortunately I have been supplied with CAD drawings and they are wacky profiles. Several different profiles, all one-offs. Is there any way for a RT component to read a file when it initializes? I could store the profile in a text file which I could generate with SheetCam.
