poppabear10,
tried your approach?? Here's what I did:
1. X0 and marked the location with my dial meter and with a pcs of tape along the X axis and placed a mark at Xo.
2. ran the table out to X-1 and placed a mark on the tape and the dial indicator read.002 less than x-1 (DRO) read -1.0196.
3. ran the table to X+1 and placed mark on tape (DRO) read .9968.
4. ran table to X0, dial indicator read O (DRO) read -.0220.
All these reading were with a .002 backlash in Mach III
SECOND RUN:
1. Zero DRO
2. Ran to X-1 (DRO) .9978, X0 DRO at .0002, X+1 DR) at 1.0188,X0 at .0220
THIRD RUN:
1. Zero DRO
Ran to X-1 (DR0) at 1.0198, X) at .0220, X1 at .9968 & X0 at .0002
As you can see the numbers keep changing even though I haven't changes any motor steps or backlash. Any suggestions?????
