Looking for some help doing a G55 work coordinate change in Mastercam. I have a Milltronics Partner I with a Centurion 6 control and using Mastercam 8.1. How do I get mastercam to change from a G54 to a G55 work coordinate ? I tried changing the misc. values field which I thought would put a G55 in the post, but it does not. Any help would greatly be appreciated.

V8 is a bit old,
I seem to remember that the MI#1 controlled the type of work co-ord system
and the post controlled what was output

I think it used -1, 0, 1, 2, values. where 1 was for a G54 output, but have you tried putting 55 for each op

If this doesn't work, then it may have to be a post mod that is needed, we would need to see the post for any suggestions to be given

I have tried changing that in Mastercam already. I have tried -1,0,1,2,54,55 and nothing I put in there will make any changes to the post. There is no G54 it the post anywhere to begin with. I can manually change the post but that gets old quick.

hard to think here, but i think in the toolpath screen, there was a planes tab, and in the work offset, change from 0 to 1, on each operation you have to do that if i remember right?

This is correct.
When creating the toolpath, there is a button for T/C Plane.
In there you will see a setting for work offset.
Default is 0 for G54
Change to 1 for G55
2 for G56
Etc.
In the operations manager you can also highlight the operations and then right-click.
Under options, renumber work offsets all at once.
