The machine support from DMG is pretty top notch, they moved some mountains when my old shop was getting through the commissioning of our CTX. App support was decent, really good with anything controller related, absolute pants with CAM/post things. Overall, I really liked that machine. The only post solution IHS was willing/able to offer was an M/T environment that would post bare bones ISO. No Cycles (rough turning, threading, etc.), just good old line by line, "re-post if you need to change something at the machine". I ended up just adding a ton of modifications to MPLMASTER and made a CHOOK to generate the MPF and SPF files after being told by the post department that they couldn't do it. Hopefully there's better options available (doesn't sound like it from your post), but you guys should be all over them if the provided solution isn't coming close to expectation, it certainly wasn't provided cost free.
