Music was nice!

I think I already found most of what I was looking for, as I just found:
github.com/kcjengr/probe_basic/blob/main...toolchange_index.hal :-))

Still have to find out the best approach to map the stepper drive signal in velocity mode to
net car-ccw motion.digital-out-03
net car-cw motion.digital-out-04
 

Hi, i've build a gantry piggy back toolchanger for my router, driven by a stepper (with gear reduction) and a geneva wheel, and am looking for some quick pointers.

At this point I've got it to rotate, creating an extra axis in HAL / INI, nothing else.

I was planning to use the stepper 'velocity mode' to drive the stepper.
I envision I need to place two proximity sensors:

1. Prox sensor for homing pin
2. Prox sensor to detect an index step, for counting logic of the pockets
   
   How does the base Probe Basic configuration handle pocket homing (locating pocket nr 1), counting pockets and the drive signals to the motor?
   
   Some clips of the geneva mechanism:
   
   
   
   
   
   
   
    
   

Small update:
After updating almost all values get stored and recalled correctly.

One exception seems to be the Spindle_zero.
If manually entered, it doesn't get stored and recalled.
If measured via subroutine, it does get stored an recalled on restart of PB.

(Subroutine folder is up to date)
