Doug,

Yes in the post processor you can get it to check that CRC is on
before moving the Z. You can even force it to go to Z0.1 then engage
crc and carry on with the rest of the program.
Below is part of the post that needs to be altered:-
:GOTO = {
IF ($DELTAZ GT 0) THEN
#N #L #Z #F EOB
ENDIF
IF (($DELTAX NE 0) OR ($DELTAY NE 0)) THEN
#N #L #CRC #X #Y #F EOB
ENDIF
IF ($DELTAZ LT 0) THEN
#N #L #Z #F EOB
ENDIF }

The post is just a straight forward text file thatcan be edited with
notepad or wordpad.
