Shift Home Position on Virtual Machine

Hi Guys,

We recently purchased a 9-12-8 Global S machine with a scanning head. The length of the indexing portion (scanning head + longer tip) kind of freaked us out, and we wanted to be able to simulate the machine offline in order to catch collisions between the head or probe and the legs of the bridge. However, the closest model in the PC-DMIS (2019 R1) model list is the 9-12-8 Evo. The hardware dimensions seem close enough to use, but the home positions of this virtual machine and our physical machine differ by several inches. This is a problem because when we put the CAD model on the same granite position as in the real world, there is a large offset from reality on the physical machine. I could ditch the virtual machine and run my manual alignment to get it to work online, but a better solution would seem to be to move the home position on the virtual machine to better correlate with reality.

From what I've found on this forum already, it seems like many of you have done similar things with the machine models. I've played around with the usermachine.dat file a little bit (starting with a copy of the Global Evo 9-12-8 from machine.dat), but it's not at all clear to me from the help file what I would need to do change the origin/start point/home position, or even if those are in fact the same. Could any of you point me in the right direction? Thank you.

Alright here goes:

First:
Create a custom machine of your current machine. I run version 2015.1

1. go to C:\Program Files\WAI\PC-DMIS 2015.1 64-bit
2. open MACHINE.DAT
3. copy your machine from (for me it's)

ITEM:GLOBAL_B&S_7-10-7 ARM
cadgeom 0 -1000 0 1 0 0 0 1 0 0 0 1 1 global_7-10-7.draw

cadgeom 0 0 0 0 1 0 0 0 1 1 0 0 6 global_B&S_xgraph_9-X-X.draw
linearjoint 0 0 0 0 1 0 0 0 -700 0 z axis
cadgeom 0 0 0 0 -1 0 1 0 0 0 0 1 4 global_7-10-7.draw
connect 0 0 0 0 0 1 ARM

4. go to C:\ProgramData\WAI\PC-DMIS\2015.1
5. create USERMACHINE.DAT
6. paste your machine from step #3
7. rename your machine and edit your axis (for me it's). Notice I just added an extra "G" to machine name.

ITEM:GGLOBAL_B&S_7-10-7 ARM
cadgeom 0 -1000 -22.62 1 0 0 0 1 0 0 0 1 1 global_7-10-7.draw

cadgeom 200 0 0 0 1 0 1 0 0 0 1 0 0 global_B&S_ygraph_9-X-X.draw

cadgeom 0 0 -22.62 0 1 0 0 0 1 1 0 0 6 global_B&S_xgraph_9-X-X.draw
linearjoint 0 36.77 0 0 1 0 0 0 -700 0 z axis
cadgeom 0 0 0 0 -1 0 1 0 0 0 0 1 4 global_7-10-7.draw
connect 0 0 0 0 0 1 ARM

8. Save USERMACHINE.DAT and close
9. In PcDmis go to Insert | Hardware Definition | Machine and pick your custom machine (for me it's "GGLOBAL_B&S_7-10-7 ARM")

Dialing the machine to your virtual machine will take some creativeness let us know if your need ideas.
