I really wanted to like this probe, but it just wasn’t reliable for my set up. If you’ve got a matt & opaque bed, then it will probably work fine. But if your build surface is reflective, or even slightly transparent, you’ll get very different Z trigger heights depending on where you probe. I have a sheet of PrintBite+ attached to a glass sheet, on a PCB heater.
In the end I replaced it with a BLTouch and this is working much more consistently and giving much more believable results.

It does as advertised and appears to be very accurate. i use it with the duet 3d wi fi board. i am that impressed with duet thinking of buying another for my bigger printer.

Cheaper than a bltouch, requires less wiring/setup and is a much better probe in my opinion, it is however a little more awkward to mount, this is the latest v1.3 version and i highly recommend it, setting up my z height and map has never been so easy!

Big improvement on the standard Ormerod probe.

I mean it’s not cheap (that’s why 4/5 value for money) but it’s amazing how much better it is than the chinese clones. not sure it is worth the money for everybody, but it sure was for me. does work on the stupid geeetech build surface (that i hate) and borosilicate glass. did not have luck with my 3d printer tape though. much faster and more accurate than bltouch tho
