okay, so I did finally figure this out! And it does work as you say. Thanks for your help!

You need to do the pmesh wash as we have come to call it. Bring the STL into the Mastercam file. Make a stock model out of it and then convert the Stock model to a PMesh to a different level. Go back and clear the STL as the original selection and now pick the pmesh. Now it works most of the time, but not all of the time with the standard settings. Sometimes we have to kick the tolerance up in the stock model to #1 make it smaller to manger and #2 to make it water tight. Now you can delete the original STL to reduce file size.

Hey man thank you so much. It work!!! I changed to exactly how you had it and tested it and it did retract and did not break movement. I'm excited not having to spend half an hour editing the program.

brk_mv_head : no$ #Break the 5 axis moves to remove gouge brk_max_ang : -1 #'brk_mv_head' maximum angle move, applied if chordal Setting those two variables should disable the "breaking behavior". For proof; leave 'brk_mv_head' set to 'yes$', and set 'brk_max_ang' to '30.'. That will cause the Post to "break the moves" every 30 degrees, instead of every "1 degree". Are you 100% certain of exactly which Post you are using? MP can grab a different Post Processor (in another location), depending on where the copies of your Post are located. For debugging something like this, I typically add a String Literal line to 'psof$', so that I can be 100% sure I'm posting from the Post that I'm actually editing in the text editor. psof$ #Start of file for non-zero tool "TEST POST", e$ That way I can be sure of which Post is doing the work. If you want to be sure "at the time of posting", you can press the "G1" button to Post, and when the dialog box comes up, press and hold CTRL + SHIFT + ALT, and while holding those down, press "P" on the keyboard. That will activate the "Select Post" button, and allow you to browse and select a specific Post Processor. If you are creating a "Test Post" to play around with, you will need to copy the ".PST" file, and the ".PSB" file, for MP to work when you Post the code. You must have two files with the exact same Post name, but one needs a .PST extension, and the other a .PSB.

Just don't put a learning curve into the table.

The tilt range are in symmetrical, it said -110/+110. Our J600/5x Variaxis have -120/+90 B-Angle.
