Good morning Nick and Colin, Thanks very much for your advice. My original question was regarding the items shown in my screenshot; the items that show up in the Custom Macros list (GUI dropdown menu) right out of the box when Mastercam/Productivity+ are installed. Examples: Cone Measure, Intermediate Point, Measured Sphere, Touch Test, etc. When you click to use them, there is some Help Information that displays for each field. It ranges in quality from "very good" to "somewhat vague". That's why I was reaching out for any tips-and-tricks that people have discovered while using these particular cycles. In the time since I wrote this post, I've begun using some of the cycles and getting a feel for how they work. Some work perfectly; others are flat-out broken (Productivity+ is not outputting the necessary subroutines to run them). A rep from CNC Software has told me that some of them are actually incompatible with Mastercam (they're only shown because they're leftover from Renishaw's standalone Productivity+ software). I hope that some on-site training from Renishaw will indeed be in my future; and I hope to have a list of good questions to ask if/when that happens. I did not consider the possibility of developing my own Custom Macros, integrated with Productivity+. I am probably a year away from trying anything like that, but now you've started the wheels turning in the back of my mind. Thank you for the ideas. -Josh

The Renishaw rep I talked to said there is no documentation for the custom macros; Renishaw only offers on-site training to explain them. I found this answer surprising.

Within the Probing Dialog, there are a number of Custom Macros available for use. They don't show any toolpath preview (no backplot), and don't have much documentation. Does anyone have any tips & tricks they'd be willing to share? Or notes about what works and what doesn't? One interesting issue I'm currently seeing: If I use the "Measured Sphere" command and generate NC code, I see the code calls G65P2301. But when I click "Run Macro File Wizard", I don't get any O2301; I get a list of 72 programs ending in O2207. In my RenMF I have "_P_SPHERE_FIT 2301". I would think that this would cause a O2301 to be generated, but apparently not.
