Lathe work offset - first toolpath is WRONG offset

[ThickChips]

Hi,

Unsure if this is an MC issue or issue with my post processor.

I have 2 toolpath groups. First group I want on G55. Second group on G54.

Spindle origin for G55 is value of 1 (manual).

Spindle origin for G54 is value of 0 (manual).

When posting all toolpaths. The very first op is G54. Not G55 as defined in origin parameters for the toolpath. This has happened on other files for me. 

Any suggestions? Thanks a lot

Some posts have defaults workoffset output because of the automatic workoffset creation that was added about 10 years ago.  Seems the default post for this machine is also defaulted to do that.

@crazy^millman Thanks for your insight. I will have to reach out to our developer.

Did you by change change the mi1 to use 2 for work offsets?

If the value is anything else then you get the default output.

# mi1 - Work coordinate system: (home_type)
#       -1 = Reference return / Tool offset positioning.
#       0 = G50 with the X and Z home positions.
#       1 = X and Z home positions.
#       2 = WCS of G54, G55.... based on Mastercam settings.
