I'll take a look. Sounds like this might be very helpful. Thanks a bunch!

I think I solved that problem in Emcoturn 220 integration and went even
further. I added a protection of lost steps with the sensor. Here is my

Hi Jon
I have it feeding back slowly to latch the proximity switch, but it's
picking up from an encoder pulse that it found 6 inches away from the home
position unless I move the machine close to the switch, close Linuxcnc,
reload LinuxCNC and command a zero return from there.
I disconnected the

OK, without encoders, then you are limited by the servo

Normal spur gears will do this too if the tooth shape is wrong. To get the
tooth shape correct you either have to understand some math or copy a
correctly designed gear. It could be that the designer got the shape of
the cycloid gear wrong. If so you can't use his STL files even if your

Hi Jon
No encoders. Besides the 7i76e and raspberry pi, the machine is using the
original steppers and electronics. Emco used a double switch home sequence
on this machine - mechanical "rough" home and proximity "fine" home. I got
this to work last night, but it's not working properly. It seems

The output disc seems to be rotating in a jerky manner.
This could be a video compression artifact, or related to
precision of the parts.

Lucky the proxy is PNP
Wire the proxy in series with the switch
- the proxy will pull the line UP
- the proxy Only has power when the switch is closed
- so the home position is only valid if the switch is closed AND the proxy
is active AND the proxy is interrupted. Then the line will get pulled
