Suggestion for auto tool offset and autotraming. about jubilee HOT 1 OPEN

Another option is design a "zero-set" tool offset ...setter. Basically just a simple tool head carrier with a z-screw and a piezo sensor. When you build or modify an existing tool, set it on the device, activate it, and it lowers the head down to the piezo sensor, then records the offset into whatever tool table entry you designate. Think of it like a tool probe offset fixture on a CNC mill, just not bolted to the machine. Probably complete overkill, but it'd be both fast and easy to build or modify tools without spending an hour getting the offsets perfect. I'm not even sure you'd need the stability of a full linear rail since you're just measuring Z offset length. Just a length of aluminum extrusion, a really short leadscrew, (40-60mm?) a stepper, some wheels designed to run along aforementioned extrusion, and the piezo sensor, along with whatever rendition of the tool changer lock mechanism makes sense. (can be hand-actuated to keep cost down)
