Setup for Chevalier Lathe/Pragati Tool Turret

I just got done installing/wiring a Allin1DC controller on a Chevalier Lathe - I have gone through the initial setup and everything seems to be working fine to this point. I was provided with a wiring schematic for the Tool Turret, but from what I can tell, there are additional parameters and PLC that are needed to be able to operate the Pragati Tool changer, which was not included.
I am new to this, so any help/direction is appreciated - if you need a report, please let me know.
Thanks

Here is an example PLC program that controls a Pragati turret on a toolroom lathe with Allin1DC.

This machine had a manually-shifted 3-speed headstock, so Aux1/Aux4/Aux7 are used to indicate the gear range.

It had a pneumatic collet closer, which is controlled with M10/M11 and the Aux9 key.

It did not require support for VCP or wireless MPG, so that code was not added.

Your description is very similiar - this is a weekend project for me, so I will look at the src file then - do you have a list of any specific parameters (Setup/Config/parameters) that need to be set for the turret to work correctly?
Thanks

Parameter 6 = 1, to tell CNC12 and the PLC program that you have an automatic tool changer.
Parameter 161 = 8 (perhaps depending on model), to tell the PLC how many stations the turret has.

cncsnw is for hire. He is reasonable, knows the Centroid Control and could get it done for you.
His website is www.cncsnw.com
Marc is a great guy, and has years of experience with Centroid and has help write many of the Centroid PLC's
Maybe worth your while pay him to finish it off for you.
