FADAL RETROFIT ATC

What would the best approach be to programming the geneva ATC on my FADAL? The machine is up and running with manual tool changes currently. I have added 4.7k pullups to the hall sensors and the inputs respond great. I am currently working on the code in python but it seems that some basic python commands do not work. Any help would be appreciated. I attached the python script
that i have written so far.

I would suggest the "carousel" HAL component as at least part of the answer.

you may show a Image of the ATC
to get some more information
but as Andy sugested it is most likly to use the Carousell.comp to get ahed working ATC
