Techno CNC Post Processor custom tool change location

[TaylorAus]

Hello, we have a Techno CNC Router LC Series and I am trying to program it so that tool changes happen in the center of the model, rather than at the origin (0,0,0). For context, it is 3 models that are the exact same, just spaced 16 inches apart from the origin. I am using the Fusion 360 Techno CNC router post, and from what I gathered I can go in and edit the post processor code, but I am unfamiliar. Is there an easier way to do it without changing the code? I want it to go to (x0 y20 z2) on the first body, (x16 y20 z2) on the second body, and (x32 Y20 z2) on the third.

What are these "bodies" that you speak of? Are you referring to separate parts that are being machined, and thus, separate work offsets?

Are these positions always going to be the same?

Couple of ways you can do it:

1) Set your origin to the center of the models. Edit your post to go to G0 X0 Y0 (instead of G53 X0Y0)

2) Continue using your current origin definition, but edit the post to have some logic that works out "oh, it's G55 that's active, I need to go here"

attached is the nc code example. At the end of the previous toolpath (tool 31) I want it to make the moves to the coordinates so that we can do a manual tool change. The M06 code stops our machine in order to do so even though we do not have an atc.

Below is a picture of the models, for context. We need to set our origin at these pins because they have a specific coordinate on the cnc router for us to mass produce.
