Problem with homing ATC step motor

Thanks for your support, I really don't know how to implement it physically, the changer I'm designing has 6 tools, do you have any photos or diagrams of how to make it? In addition, I have not found any complete example of the configuration of an ATC for a lathe, most are for 3-axis machines, do you have any configuration that you can help me with?

What parts don't you understand? Are you looking for a complete mechanical design, or just help with the position feedback aspects?

Only position Feedback,The mechanical part is already working

I would probably use proximity sensors and drilled holes as targets.
Do you have any pics of the design or a 3D model to share?

Tomorrow I publish the photos of the ATC. Regarding the sensors, I think I will use the hall effect switch, which are smaller and instead of drill holes, I will use neodymium magnets glued to a disk simulating a 3-bit gray code plus another for the index or strobe. in total 4 hall effect switch.

No eBay APP ID and/or Cert ID defined in Kunena configuration

I shy away from magnets on machine tools, they attract swarf.

There are some fairly small inductive sensors:  as an example. You need ones (like these) where the metal case comes right to the end. The others can't work buried in a hole in metal.
