Could anyone give me any pointers please. We have a 2000 VF4 haas mill which has been running fine from new, recently we have tried some new highspeed toolpaths from a cam system. The machine couldnt hack it and was jerking. Is there any settings that could be altered to maybe help this. Please note we were cutting at F2000. mm/min and had to slow down to about F800. to get a smooth movement. We do not have the highspeed option. Also we have an older machine a 1994 model that we run some test pieces on before putting the live job on the newer machine and this run fine at F2000. and didnt start jerking till around F2300. I have also seen there is a setting 85 was set at 0.127 tried making that smaller and bigger with no noticeable effect.
Any advice greatly appreciated.
