For 90% of people, the CIMCO add on will be way less setup pain and get you there faster, cheaper, and easier utilizing the I+ macros already set up on the machine. For 10% of the people, I haven't seen anything else on the market give the ease of use of setting up complex logic (multiple nested If/Then/Else logic) like P+ can do. Inspection+ are the macros that ship with the probe on your machine. If you use the GoProbe app on your phone (or the Renishaw manual) to enter, say, G65P9901M2.D0.5S54. to probe a .5" bore, that's Inspection+. Productivity+ was developed by Renishaw as a stand alone program (yes, you can buy just P+, not integrated into Mastercam!). The problem was they can't trust the I+ macros to be the same everywhere, that no one edited them, and that they could support all the logic they wanted so they developed the P+ macros. You'll have two sets of macros loaded onto your machine, two sets of calibration data in the parameters, etc. P+ coming out of Mastercam will ONLY use P+ macros.

I would not recommend inspecting a part using the same machine that made said part. Been there, done that.

the only way to do this is to save the deburr operation backplot as geometry then do a C axis face contour on that geometry then the post will post as C and X or if using G112 it will output correctly

So many questions to give you some good feedback... What kind of machine/Pallet Pool? What type of work? What type of materials? Cube size/Weight of parts? Quantity of each part#? How good are your operators? How well can they follow instructions? Can you do critical features with dedicated tooling/offsets so you know these features are dialed in and don't need to probe? What is the avg material cost for these parts? How many shifts do you run? To really get a 5 axis cell to shine and pump out work takes a COMPREHENSIVE look at the entire process as a whole. This includes the business management side as well because when you really get the parts cranking 24/7 you run into a whole host of problems that have nothing to do with the actual machining... Its really amazing what one spindle can churn out with the right support and encouragement!

Seems like its in spec. No problem here...

wet cardboard is the deluxe upgrade

Yes, but the duct tape, bailing wire and chewing gum holding those UMC-750's together is highly susceptible to thermal expansion and compression.
