DIY CNC Touch Probe XYZ Axis 3D Digitizing Edge Finder 3-Coordinate Measuring Sensor Kit with 6 mm Shank & 2.0 mm Tungsten Steel Ball Tip

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.

The media could not be loaded. It is plug and play from China. Unbelievable!One of the very few 5* I’ve ever given. As others have said it’s a great tool.

The media could not be loaded. Very accurate for the price deffently pick up!I bought two and use other as tool setter and have a spare just incase. I also just recently purchased there ruby probe will make a review on that.It was .020 out when i got it probably from shipping but i always verify. just took 10mins and slowly dialed her in.Accupro collet was used.

After some headache, it is possible with a 5V Relay to add to GRBL machines. Probe functions well, though I have not done a repeatability test.

This is "Deadly Accurate" it was with in 0.0004" out of the box ... until I crashed it and broke the stylist mount and need to replace it.The thing that helped me decide to purchase this was the parts catalog and the comment"1. if any listed parts needed, feel to con-tact us."Well, I do need a part listed, but nowhere can I find how to contact them .... or who/where to feel.I assume some day someone will tell me how to "feel" to contact them.However ...I did order another one IT IS that GoodMike

I'm using this PGFUN Probe on my 4ftx8ft ShopBot PRS converted to run with Centroid Acorn. Hooking it up was easier than I expected and my first tests of it impressive. I did a find center of bore routine repeatedly with a variation of only 0.0004" - or 0.01016 mm. Time will tell how durable it is.

Love the small size. Very accurate.
