After completing two MasterCam classes and with my instructor praising mpmaster, ( he was a great instructor)  I decided to try it out.
My current post works well, although I wanted to see what mpmaster has that's better. What I found out
already is a problem with the B-Axis rotation. This could simply be an adjustment, although I do not know
where to look. The following code is a snippet form my current post and mpmaster in which the b-axis
is a problem because I need a M62 on the same line as the "B" call out, followed up with a "M61" on the next line.  The second issue is the transform-rotate
which does not post a "B" movement or M62 call out.

Thank you in advance for clarifications to this issue.

Is the M62/M61 used for unlocking and locking the B Axis? MPMaster probably has a switch that allows you to output rotary lock/unlock codes. You just need to enable it inside the post.

I'm not sure about the Transform - Rotate issue, but I'm sure someone who uses MPMaster will know.

There is  away to force the B output when there is no rotation, the current output for locking and unlocking is M10 & M11.

There is a line of code in the post block that handles rotation that will needed to be uncommented (remove the #)

Do a search in the post for lock and you will find the switch to turn on the locking output, also you will need to find the M10/11 address and it can be changed to M62/M61

As far as controling where the B axis and M62/61 code are output you will need to reset the order in the posf/ptoolchange common and the ptoolchange post blocks.
