Over the past year and a bit I have been faffing with limit switches. My shapeoko didn’t come with them (early model).
I started my journey with micro switches, moved to slightly larger ones then onto hall effect magnetic sensors, I then tried some proximity switches with no luck, however I now have a full set of working proximity switches. The trick was to use a lower voltage.
The beauty of proximity switches is there is no contact - it detects the metal body of the machine and is powered through a 5v pin like the touch probe
I did a quick video for anyone who wants to take a look.
here are the limit switches I ordered in case anyone wants to have a go - importantly they are NO and 6-36V and have a pretty light on them
If anyone wants the design for the Y axis mount here it is:
My Z axis mount is unique to my Z axis so I won’t share that and X is mounted with hot glue, although I might change this shortly, if I do I will update.
