Stuart, In your axis compensation plan, do you assume that the axes are perfectly straight and not bowed? Such as table sag at the end of travels.

I am running the emc-dev (trunk) from the git download. The machine is running and looking/moving as expected. Measuring and adjusting is the next task. I will assume the X axis is the perfect axis/joint combination and comp everything to the X axis and the table top. My plan is to: (in this order) comp the Y axis to X comp the Y axis to Z (table top) comp the Z axis to X comp the Z axis to Y comp the parallelism of the A and X axes comp the parallelism of the B and Y axes comp the construction errors of the AB head (the spindle centerline does not project exactly through either the A or B axes centerliines of rotation having some fun now (sweet) thanks (many thanks to the developers for this incredible EMC software) this sow's ear is looking like a denim (not quite silk) purse. Stuart ps - axis jog would be especially nice for this :) -- you can lead a person to knowledge but you cannot make him think ---------------------------------------------------------------------------- -- _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
