Hi All This thread and it's follow on triggered my interest, so I just snagged a Renishaw MP3 probe on Ebay and now face the task of interfacing this to my New CNC mill which I am due to pickup later this week. I ordered the mill with LinuxCNC using the Mesa cards to interface to the computer. The mill uses Servo's on X,Y,Z. It is a small mill with a 12 position tool changer, thus I am hoping to put the probe in one of the pockets and use it to sense work-piece position, and also to digitize. While this is my Hobby mill I am hoping to get close to 100micro inches repeatability. I would appreciate any pointers to available data for building/buying a relatively inexpensive transmitter receiver for this purpose.
