Review: Good - Good
Review: same size every time - while 3018 cnc machines are not exactly what you might call state of the art, they do function really well as an introduction to all things CAD and CNC. Having the ability to perfectly reach a desired depth to set your zero consistently every single time cannot be underestimated. This z-probe gets straight to the point with no bells or whistles, though to make the best of it you will need to purchase (or borrow) a set of very accurate calipers. I know these are mass produced, but if they came with precise size dimensions in the packaging that would be awesome. Worth every single penny regardless.

- Z-Axis tool setting touch probe works with Mach3 and GRBL(Candle).

## Questions & Answers

**Q: How much variation is there across the surface of the probe?**
A: The metal part is fine with no significant variation (although it is grooved so I guess a very sharp v bit might have tiny variation) its the plastic holder that needed work on mine.  I ended up taking the metal out and tapping a small screw on the side.

### ⭐⭐⭐ Not a Dupont connector
*by E***E on 21 March 2022*

The connector on this probe is one for a dedicated 2 pin connector, and doesn't fit the 0.1" headers on my control board. For all I know, it's right for a Sainsmart control board, but the product photos seem to go out of their way to not show the connector.
