ProbeIt for Mach3 and ProbeIt for UCCNC are similar in some respects, but quite a bit different in other ways. As the UCCNC version is written in .NET and is not constrained by being a ‘macro based’ wizard for Mach3, the UCCNC version is able to provide much more capabilities and will be developed to be more powerful than the Mach3 version.

** WARNING For Mach3 version: If you have a generic Chinese made external motion device, such as a ‘Digital Dream’ or similar, use extreme caution trying this wizard. Probing is not implemented correctly in these devices, and they have been reported to produce random moves which may damage your probe. This has been reported by a few users now.
