You might get better results by posting this in the Thermwood forum (and giving it a more descriptive subject). This forum is just for eCabinets software.
You will need to set up a fixture offset using the G52L#. At this time the Profile modeler will not let you use the G901 fixture offset like Control nesting does. So you just need to set up a fixture offset in the fixture offset table, and use the x and y coordinates in your G901 offset.
Open your m999 macro (Open a new blank program. Enter text M999 on any line. Then block step+ on the M999 line, to open the macro. You may need to delete it after you are done.)
scroll down until you find the G901 X and Y values. (write these values down on a sheet of paper)
go into your fixture offset table and choose offset 52
Apply the X and Y values and save.
Now when you are in Profile modeler goto "OPERATIONS">"DEFAULTS"
Goto the CNC offset portion, and select "Fixture G52L#"
Then select 52 for the fixture offset.
Now when you post out the code your program should start in the correct place.
Note: If your xshift and y shift are selected in Control Nesting they will also need to be selected in the Profile Modeler.
