Hi all, the 3D probe shown in the attached photo is being sold on the web by several vendors, ranging from AliExpress through eBay to CNC system sellers.  It looks quite nice, having only a 6mm shank and being quite short so good for machines with limited daylight.

Does anyone have any experience with these they could share please?

Good feedback on the mycncuk forum so I've ordered one.

 Hi John,
  I have one similar to that one I got from https://topcom.cz/products/dig3d/dig3dlpm/
 Depending on how your probe input works you will need either a NPN or a PNP type. they work very well.

Thanks Charlie, here's hoping.
