I am new to Mastercam. Where is the setting in Mastercam to switch from posting G92 home positions to posting work fixture offsets G54-G59?

I am using MILLDEFAULT.MMD and MPFAN.PST and running Mastercam X.

Misc Intergers #1 would have to be set for each operation.

To have permanent setting
Don't forget to set a default in the Machine definitions
it will ammend the text statements at the end of your post

if successful, you'll have something like this at the end of your post
( we use "G15 H" work offset #s)

..
[misc integers]
1. "Work Coordinates [0-1=G92, 2=G15 Hxx's]" //2
2. "Absolute or Incremental [0=ABS, 1=INC]"
3. "Reference Return [0=G28, 1=G30]"
..

When I start Mastercam, no machine group is default, is this normal?

I found the area you are talking about by going to Machine Type, Machine Definiton Manager and navigating to Misc. INT/Real Values. It is already set to 2 G54's anyway.

What am I missing?

You must have "the" machine in your Op manager to actually edit the machine and control definitions for that machine.

Yes, you say you have checked the settings, but this is how you start a "new" machine from scratch.
As soon as you load the machine definition file , it will replace any settings currently set ( machine, control and post )

another way you can do it is once you do a operation (say drill as an example) when you are in the toolpath parameters page, you select misc values, and on the first square you just change the 0 to a 2 . maybe that can help some

If your using X (not x2 or x3) the Misc Values page will have a check box at the bottom of the page that says something like "Use the default Post values". If it's check un-check it. If it's un-checked, check it. There is a way to set this as the default. I'd have to look thru my old X notes & Videos.

Pretty sure it gets covered in here.

The misc. values page was the key, I can now post work fixture offsets. Thank you all for the help!
