Hi Robert, Im very interested in this too, are you trying to solve slow gcode or smooth movement? or both? one problems i find doing a filament winder, linear X and rot A, was the lack of blending between them. Also the diferent interpretation of feed between linear and angular (regular feed or non inverse time feed rate) cause trouble, when a move changes from linear to angular. Axis backplot draw the gcode correctly, and keeps me thinking in a manner to ensure constant surface speed doing blending based in tip point absolute spatial speed calculations but my lack of programming skills drop me. Im willing to help in whetever i can....could you explain more about your particular branch, i like to test it. Regards Rick
