I'm thinking about building a touch probe - the kind with the three little arms, and ball-bearing contacts. I've been using a rigid probe, but Mach keeps randomly screwing up, and about every 3 months breaks it off.
So, the question is, how does one go about aligning the probe tip to the spindle centerline? I want to use this for machine setup, so it needs to be very accurate. Seems to me it must be a huge PITA to get it precisely aligned and centered, I assume by using three screws to tilt the PCB, or similar arrangement.
