I have the following setup: CNC USB controller Mk3/4 (4 axis) Windows 7 64 bit CNC USB Controller software version 2.10.1609.3001 C-Beam Machine Mechanical Bundle When I click the Tool Measurement Icon the router is sent to the max y position (first thing) and stops there. I am using a movable sensor. What settings should I have for the Tool sensor? The limit switch should be ok.
