Hi, Thankyou for your test, you have save me much time, but I'm a little disappointed becouse I think that I'm stupid becouse I can't find a way to do the job ... is it impossible that in all the time that linuxcnc exist no one had my same problem. Well, a way illustrated from Kirk Wallace seems good but I'm not sure on how implement the trik, I don't know how to force the commanded position from the motion part to be at a fixed point even if it have a jog or G command, I have made some test with the axis.N.motor-pos-fb but the tracking error remain. I hope in a miracle....or someone much clever than me.
