When you buy a Haas with the probing option included, you get a Renishaw OMP-40 probe, tool setter, and a host of programming options.
On the front end there are interfaces that allow some basic probing for setup. Easy, but limited.
What most folks don't know is that in the backgroud you have all the Renishaw Inspection Plus macros. A most know, these are easily written programs at the control or off-line. Many CAM systems (including Fusion 360) have modules that allow you to more quickly develop these programs, although manually writing them is not difficult. But none of these modules give you the ability to receive probing results back. For that you need something like CNC Reporter.
Mastercam does have a probing module built by Renishaw called Productivity Plus. However, it can be painful to get working, somewhat inconvenient to use, and does not share any of the base macro programming already on the Haas. If a shop has a requirement to produce comprehensive in-process or inspection programs, then the Mastercam solution is worth looking at.
Getting probing data out of a Haas is very easy. On pre-NGC's, its a simple RS232 connection to the PC combined with an application like CNC Reporter to collect the result and put them in reports and spreadsheets. For an NGC, its over the network and also very easy.
