Yes, it’s very cool to be able to have a reusable zero. I have decided not to try and disable the z home. Now that I have a vacuum shoe, I can’t see the bit anymore, and I now realize that it will be easy to create a touchplate – hooks up exactly the same as the endstops. Being able to get a reproducible zero on the z axis is as important as the x and y.
I haven’t made the touchplate yet – hopefully tomorrow. I’ll let you know how it goes.
