hey guys I have a relatively high speed machine (3kw motors 16mm pitch ballscrews) 35mm linear rails, and weights 5.8 ton. I think it used to go 20m/min with the heidenhain control. I have been noticing a bit of jumping around when doing parallel finishing 3d passed on it at high speed. and talked to a couple of linuxcnc guys and found out that linuxcnc doesn't have any jerk control. just sending out a email here seeing what the current progress is on that.
at high speed high precision linuxcnc definitely needs some work at some stage. apart from this I am completely happy with linuxcnc. this would be a nice thing to solve though. and if someone with the right skills wanted to fix it I would be happy as to chip in to pay something for the time. as I run a business in my machine shop where everything runs linuxcnc in the mean time I will try to get around the issue by programming in cam regards Andrew _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
