Features
- 0.005mm Repeatability with Adjustable Precision: Delivers high-precision edge and position measurement with a repeatability of 0.005mm/0.0002". If the ruby ball shows excess runout during testing, simply refer to the video tutorial we upload and adjust the 4 silver screws to calibrate the center deflection to 0, ensuring consistent workpiece alignment and tight tolerance control for demanding CNC tasks
- CF-38 3D Probing & Insulating Material Compatibility: Probes in X, Y and +Z directions for multi-axis setup and measurement. Mainly used for quickly determining the edges, centers, and surface zero points of parts on CNC machining centers, engraving units, and lathes. Designed to also detect insulating materials, expanding application beyond conventional conductive-only touch probes
- Long Service Life Built to Endure: The tungsten steel probe rod and 3mm ruby ball tip provide exceptional wear resistance, maintaining accuracy over millions of cycles. Gold-plated internal contacts resist corrosion and ensure consistent triggering. With a rated trigger life up to 3,000,000 cycles, this edge finder reduces downtime and replacement costs, ideal for continuous CNC production work
- Multi-Layer Waterproof & Dustproof Design: Engineered with multiple sealing structures to effectively resist coolant, oil, and dust ingress, protecting internal components and gold-plated contacts. This design extends service life and maintains accurate triggering even in harsh, wet environments, reducing maintenance needs for consistent daily performance, for reliable, long-term use
- Compact Structure with Safe Overtravel: Integrated safety stroke of 20 in XY plane and +2.5mm in Z prevents damage from overtravel during fast probing. The compact body with 8mm (5/16") straight shank mounts easily in tight tool holders, fitting a variety of CNC machining centers, engraving machines, and lathe mills, simplifying automated production integration

Clips and a wire -what else can go wrong, right? 🙃 what I did was to solder a neodymium magnet to one of the leads end, the other end with the aligator clips. I then did away with the disk and plate. For my application I just needed a simple close circuit. I use the magnet on the spindle’s collet, right above the bit -in case I accidentally start it, the magnet quickly detaches and there’s no harm.

I purchased this because CNCTOPBAOS was the same supplier for my new 3018 machine. It did not, you have to put a completely different connector on the wire to work. This fact should have been made crystal clear on the description because most people will not have connector required to plug into the controller board.

Was easy to set up on my Shopbot cnc. Works as I exspected it to.

This seemed great until I tried to actually use it. It was basically impossible to indicate the stylus in. It seemed like there was play in the body despite all screws being tight. Lot of potential but not precise enough to be useful.

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

It does work even on wood and plastic, a bit of a setup curve but worth it, definitely a good idea and a nice time saver
