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)

Hi Endian,

Here is a example for you. I assume you can clone the repository, do the install script.
Then you can try it out.

Hi,
I tried with stlink and j-link with errors.I also tried reversing swdio and swclk, because I saw images of pins connected differently.

Hey Scott,
Sorry to bug you again, but just wanted to let you know I finally managed to flash the firmware and ping 10.10.10.10! Next up is diving into the LinuxCNC side of things.

I’m planning to document everything I did to get it all working and might make a YouTube video showing the steps once my exams are out of the way next week. Also, I was thinking it’d be cool to contribute to the project documentation if there’s any way I can help out.


Thanks again for all your help – really appreciate it!

Hi,
how did you solve the flash problems?
could you please insert the strings you inserted? Photos of the connection pins? Did you power the NVEM V5 at 12V or 24V? Did you press the button?
