We slapped a giant Clear Path Servo from Technik on the 4th axis of our PCNC770. All was well while under Mach3 control but with the path pilot upgrade I can't seem to make the deceleration work quite right with interpolated moves and it's causing our 4th axis work to come out twisted. See video for details. Anyone have any idea what parameters I need to tweak? I'm not familiar with LinuxCNC or PathPilot yet so this one has me stumped.
