REMAP M6 FOR GENEVA ATC

Why are you using "carousel"?

The fragment of G-code I gave you a number of posts back does all that carousel is doing in this case, and it should store the carousel position too.

Using carousel component seemed like a nice and clean approach. It has everything i need built in, such as turret jogging and bidirectional mode. It works like a charm other than not saving and recalling the selected pocket. What is the benefit of not using the carousel?

I admit I had forgotten about the jogging, if that is useful then carousel might be useful.
I normally think of "carousel" being mainly about decoding various types of carousel position encoders. (I wrote "carousel" but have never had a machine that needed it)

What I would suggest you do is to save the position from G-code after every tool change into a persistent variable (such as #5490). Then you need to subtract the number stored in #5490 from the required pocket position before sending it out to the carousel component. (In effect #5490 becomes a "home offset" for the carousel.)

I can think of neater ways, but most of those involve modifications to "carousel"

Where can i find the carousel source code?

github.com/LinuxCNC/linuxcnc/blob/master...onents/carousel.comp

I'm definitely not scared of diving in and learning some code but by chance is there a line or 2 i could add to pull value from #5400 parameter (current tool) at startup?
