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 and Grbl (Edge Finder-NO)

I ordered the NC version and it is stuck in the closed position. I have tried continuity and ohms testing, it will not switch to the open position. The light work as the should when compared to a functioning NO unit. Either the unit was not programed correctly or has faulty circuits. Glad I tested it before using. I will give the seller a chance to fix or replace the faulty unit before returning it to Amazon. 4/21/23: seller has shipped a replacement. Fingers crossed that it works.

I recently bent the stylus tip on my touch probe ( I was being stupid). I ordered this replacement. It arrived quickly and fit my touch probe exactly. I have been using this tip for a while now and it has performed flawlessly. I would definitely recommend ordering a couple of these to have on hand!

As a probe tip it’s fine, but only single items are available quickly . You can buy 6x for just a bit more but have wait weeks for them to be shipped from china. This is a item prone to damage and the 6 pack makes more sense

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!
