I think that I saw some signs of this when I was boring Capto sockets a few weeks ago. I didn't fully get to the bottom of it, but I think that you need to reset the eoffset before you disable the eoffset, or the offset is stored, and then further offset counts are (might be) additive. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
Re: [Emc-users] external offsets following error
Just to be more clear. The following error appears for example, if I'm turning a cam, in the moment the lift is being applied. If I just press the manual control button when the axis is not moving because it's on the base radius part, nothing happens. I suspect this is a configuration issue and I need to tweak a little bit more my config. Let me know if you need me to post my ini file.

Just to clarify a little more. This happens when I go from MDI to manual control when the spindle is turning and the eoffset is making the X axis move almost constantly. Sometimes it happens, sometimes not. Do I need to play with the eoffset AV ratio? The acceleration of that particular joint/axis is pretty high just to ensure the eoffset is applied as correctly as possible. One problem I notice is that whenever this following error occurs, my tool diameter gets corrupted. No matter if I turn eoffset to 0 and clear it. The only way to get the tool diameter ok is to home the axis again. Is this normal?

Re: [Emc-users] external offsets
oops- meat to reply to list offset-scale is set to appropriate (well) value (if not, eoffset-request stays 0 (guess how I know)).
