Post Bug: Part transfer with cutoff does not turn spindle on cutoff operation DMG Mori NLX Mill/Turn post

Using the latest DMG Mori NLX Mill/Turn post version 44132, when doing a subspindle grab then a parting operation the resulting gcode for the parting operation does not turn on the spindle. 

 

This can be tested with the Cam Samples>Post Processor>Stock transfer project. Select the "Part transfer with cutoff" setup right click, create nc program and pick the DMG Mori NLX Mill/Turn post.

Also.. 

If you do a subspindle grab, setting up for a bar pull in a setup configured for the secondary spindle it unclamps the main chuck instead of the subspindle chuck before doing a grab. Dropping the stock and leaving the sub chuck clamped.

 

Trying to work around this I setup a 3rd setup configured for the primary spindle and moved the grab, bar pull and return operations in that setup. This does clamp/unclamp the correct chucks but does not call a G54 for the new setup, also potentially crashing the subspindle.
