Probe Basic Errors after successfully probing

This is a PrintNC setup so router style setup with ER20 collet spindle. Workflow wise, I was using a 3d probe for workpiece locating and a tool setter for determining the tool offset each time a tool is loaded. Like you mentioned, since this is a collet setup I touch off each time the tool is loaded. The Z=-7.4953 value is a G54 value that I assume came from the tool offset calculation, but I may be wrong. I can go try to capture some video. It very well may be operator error.

I appreciate all the help.

yeah some video would be very helpful. so your probe length changing is not really gonna help your cause. it should be fine for x and y, but your z is gonna be all over the place. you will be better off using a non repeatable holder touchoff routine which will basically use the height between the tool setter trigger position and your finished spoilboard. and make z0 the spoilboard surface for your programs. then every tool touch off will reset the work offset based on a calculation between tool setter and spoilboard and new tool touch. other ways to do it also but im not really a router guy so maybe better posting a thread asking for router tool touchoff help from the other users doing that already.
