@Eric - Does the AVID Post Processor for Fusion support WCS changes?

For instance, when I’m doing a 2 sided part I’ll have two setups in Fusion.

Setup 1 - Part in vise, WCS 54 set to top center of the part to machine

Setup 2 - Flip the part, WCS 55 set to parallel height for Z, stationary vise face for Y, reference pin for X

However when I post process setup 2, I don’t see Fusion changing the WCS in the actual file.

I can go in and manually change to G55 but was curious if this is something that can/should happen as part of the post processing?

Michael

Ah ha! Never mind, I found the answer in this post:

> This is correct we set it that way because… This is exactly why it was done. Most users just use the default G54 WCS. In some of our video guides we show how to switch that to add different fixtures. Vectric products do not switch the WCS for you (they have no ability to do this) so when you start a job it will run on whatever the last WCS you have picked. Changing the default behavior in Fusion was done to mimic this behavior.

You can edit the machine setup to flip this feature on if you want to (machine setup in Fusion)
