CNC 3D Touch Probe Upgraded XYZ Axis Anti-roll Edge Finder Waterproof 3 Coordinate Measuring Sensor Kit with 6mm Shank & 6.5 Ft Cable, Compatible with Mach3 (Edge Finder-NO)

Starting the spindle with the tool in the collet resulted in the cord disengaging effortlessly leaving the probe rotating undamaged in the spindle. This made me super happy! I was wondering when this would happen. This probe is great for setups and couple of microns is well within tolerance for an optical touch probe. My test results were better than anticipated. I do also strike a tool setter commonly found on here without issue.(no deflection). The electrical timing difference (between the probe strike and tool setter strike) was easily calculable and repeatable allowing the operator to change tools to any tool length, and continue cutting from the same WCS, having only referenced the surface once before a multitool toolpath. I also bought the N.O version as a backup.

Item is of good quality. Tested and works as described.

I was really impressed with this touch probe! It works flawlessly on my CNC machine, making edge-finding and digitizing super easy. The tungsten steel ball tip feels durable, and the build quality is excellent. The wiring was straightforward, and the response is fast and accurate. Overall, a great product for the price!

Their definition of NO / NC seems backwards to me. It seems like NO should be 0V at rest but it's not. Instead, at rest the yellow lead is high (12V or whatever your power supply is) and it goes low when triggered by an edge. Fortunately my CNC control has both a normal and an inverted probe input so I didn't have to exchange this. This NO probe would not work in this control's edge finder port as it requires trigger=high. Once wired correctly the probe works very well. I checked runout after placing in a standard ER20 Tormach TS tool holder and TIR of the probe tip was 0.0005 out of the box before making any adjustments.
