mohsin ahmad Posted February 16, 2016 Share Posted February 16, 2016 i am facing problem while i am trying to make threads on my lathe. actually it goes off track or its path while in threading mode.i have tried g32 and g76. here is my configuration for spindle and z axis. z axis has no backlash , max following error 0.003mm. ixx28=0, 10000 counts/ revolution. for spindle encoder counts 4096/rev max spindle speed 1875rpm i7042=3 i've checked c channel pulse .its fine and updating. but problem is still there. threading goes off track about 0.1mm every round.

mohsin ahmad Posted February 21, 2016 Author Share Posted February 21, 2016 Check spindle parameter in the registry NC Pro 2 encoder counts 4096 was installed. problem was in ECT entry for time base. just change that entry and every thing is fine now.
