Thanks guys. Leon82, yes it is, so I've probed two points and calculated the angle of the error then wish to call upon the #883 where this error is stored. I now want to rotate my datum to suit this angle - I can't do this by the machine axes due to the kinematics and workpiece set-up so need to rotate the datum. If you've got any examples of using G54.4 that would be great.

Hello, I require some 5 axis simultaneous programming assistance. I am currently using a Fanuc 31i control on an SNK CMV-80S, it has an A axis head and B axis table as it's rotary axes. I wish to use a tilted work plane (G68.2) and rotate the WCS in line with an error I have previously measured and written to a variable. However on the machine we use a G43.4 TCP function and I can't get the 2 commands to work together. I have attempted using a G43 but that doesn't pick the correct tool length. Is it possible to run these commands together without the G43.4 cancelling out the tilted work plane? Please look at the code below and if anyone can point out my mistake it will be greatly appreciated. G40 G17 G94 G90 G21 G49 G91 G21 Z0 T66109 M06 G90 G54 G68.2 X0. Y353.5 Z0. I0. J0. K#883 G53.1 G43.4 D99 H99 G65<TLCK>M0 M08 M51 S995 M03 G0 X-182.534 Y428.787 A-30. B330. This program will run but it cancels out the G68.2 tilted plane so just runs as nominal part. If I've missed any info please let me know and I'll do what I can to provide it. Thanks all!
