Is it possible for me to connect the Linear Scales from CDCO Machinery to the Probotix PBX-RF board so that the scales act as home and limit switches? For example, the working area of my CNC router is 20" by 17" so the linear scales should tell Mach3 program to stop my CNC router from going beyond 17" or 20".
