Every time the probe is installed, even if the concentricity is adjusted to 1 wire, there will still be deviations when the probe is removed and installed again. So your chuck is best to buy AAA and above accuracy (concentricity <=0.005), because many chucks in China have false standards, it is recommended to use a high-precision gauge or tungsten steel rod to check the table after installing the chuck. Look at concentricity. It's best to place the dial indicator at a distance of 50mm from the chuck, which is roughly the distance between the ball head of our probe and the root of the tool handle. Review: Délais, qualité, prix c’est Ok - Bien correct Review: Well built inexpensive tool to trace 2d and 3d objects. - Was easy to set up on my Shopbot cnc. Works as I exspected it to. ## Features - Function: The three-coordinate probe can realize quick centering, edge finding, center finding, shape measurement and other functions by connecting the CNC to the knife edge - Supported software: Adapt to various control panels such as grbl control panel and Mach3; Repeatability Accuracy: 0.01 mm/ 0.0004; It solves the trouble of positioning the workpiece during the second clamping during the machining process - 3 wires: NPN-NO 3 wires: Red-VCC / DC5-24V power; Yellow: IO/ Signal Output;Black- GND/DCM; Indicator light: green light when power on, red light after triggering - Material of the probe: The shell is made of fine frosted black oxidized aluminum alloy with a flat surface anti-roll design - Material of the stylus: The probe tip/stylus is machined from stainless steel up and down, and the ball head is made of tungsten steel ball, which has the advantage of wear resistance;The concentricity is fine-tuned to within 0.05 before factory;Please measure and adjust it by yourself after receiving it;Be sure to use ER11 spring chucks of AAA or above, otherwise the concentricity of the probe tip will be affected ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | ‎Changzhou Rattm Motor Co.,Ltd | | Item Weight | 159 g | | Package Dimensions | 14.5 x 11 x 8.71 cm; 158.76 g | | Item model number | V5 | | Style | Style B | | Material | 3D Touch Probe Edge Finder-NO | | Power source type | DC | | Item Package Quantity | 1 | | Included components | 1x 3D touch probe 1x Stainless steel probe tip 1x cable | | Batteries Included? | No | | Batteries Required? | No | ## Images ![CNCTOPBAOS 3D Touch Probe Edge Finder to Find Desktop Center,V5 NPN NO 3D Edge Finder with Tip,Waterproof Anti-roll CNC Router Probe 6mm Handle Compatible with Mach3 GRBL CNC Milling Machine - Image 1](https://m.media-amazon.com/images/I/71z6ATX-l-L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Délais, qualité, prix c’est Ok *by J***G on 18 March 2026* Bien correct ### ⭐⭐⭐⭐⭐ Well built inexpensive tool to trace 2d and 3d objects. *by J***N on 6 March 2025* Was easy to set up on my Shopbot cnc. Works as I exspected it to. ### ⭐⭐⭐⭐⭐ Very accurate *by A***R on 16 December 2024* I set this up in a CNC mill, it repeated down to .0001” every time. The ruby probe measured .118” I would have preferred to see an even size like .200” for easier machine setup. The ruby probe should remain stable with temperature fluctuations. I use them all the time on the CMM ## Frequently Bought Together - CNCTOPBAOS 3D Touch Probe Edge Finder to Find Desktop Center,V5 NPN NO 3D Edge Finder with Tip,Waterproof Anti-roll CNC Router Probe 6mm Handle Compatible with Mach3 GRBL CNC Milling Machine - Z Axis Automatic Tool Setter Modifying Kit for PGFUN CNC 3D Touch Probe Edge Finder Contactor - QWORK ER20 A Collet Clamping Nuts for CNC Milling Chuck Holder Lathe, 4 Pack (Black) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/499174477-cnctopbaos-3d-touch-probe-edge-finder-to-find-desktop-center](https://www.desertcart.tn/products/499174477-cnctopbaos-3d-touch-probe-edge-finder-to-find-desktop-center) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-03*
