Hi all, Finally found a 'roundtoit'.
As a quick test of homing repeatability I mounted a piece of 6061- T6 in the vise, wrote a small program to move from homing position to the workpiece and then drill a 1/2" hole using a 0.500 carbide endmill. Hole 1 was drilled repeatably after a shut down and restart of emc including homing. As a check I drilled hole 2 only one time. Hole 1 x = 0.531 y = 0.506 Hole 2 x = 0.505 y = 0.506 Using a dial indicator I checked the repeatability of Z home. It was within a thou using a Enco 1" indicator. If this gets serious I will use a better indicator however I don't see a problem with Z. So ... back to the X axis. Fire up halscope.. monitor axis.0.home-state, axis.0.index-enable and Xindex. These may not be the correct variables to monitor but they looked like a good start to me. when axis.0.home-state goes to 16 both axis0.index-enable and Xindex go to 1. axis.0.home-state has a series of increasing values 0 4 then shortly 5 11 the shortly 12 and finally 16. What else do I need to look at? I did not do the obvious and try the same variables with halscope on either Y or Z. Duh! Only thought about it after I had shutdown everything. Hope this is enough information to diagnose the problem or recommend more troubleshooting. Thanks in advance for any help.
