I have just finished a couple of weeks testing an inexpensive limit switch on the Z and A axes of my PRT 4G. I no longer have the problem of raising either of them too high -- no more gnashing of gears immediately followed by the gnashing of my teeth.
The device consists of a magnetic reed switch (thanks Jim Frost) and a rare-earth magnet. Since the proximity switches operate in a normally open condition, they can be spliced into the harness of the existing proximity switches on the Y axis. It it not necessary to do a home-run all the way to the control box.
Once the positions of the switch and the magnet were finalized, I attached them with flexible CA glue.
