I set up a table with actual measured values. 1st col is nominal, 2nd col is actual table position read from table DRO when nominal is called while moving in a positive direction, 3rd col is actual actual table position while moving in a negative direction. This was done without a COMP_FILE and backlash set to 0. This is the table: -13.0000 -13.0000 -12.9970 -8.0000 -8.0010 -7.9997 -5.0000 -5.0010 -4.9970 -3.0000 -3.0010 -2.9970 0.0000 0.0000 0.0030 3.0000 3.0000 3.0030 5.0000 5.0000 5.00030 8.0000 7.9995 8.0040 13.0000 13.0000 13.0045
The backlash shows in the table and at the extreme positive end increases from 0.003 to 0.004. Now when I move the table for example if I am at nominal 0.0000 and table DRO indicates 0.0000 and I issue g0 x-3, I would expect that after the move the table DRO to indicate -3.000, however it indicates -2.9970. Sure the EMC says -3.0000 as it should. So it looks like the table values are being ignored. ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
