Simplify 3D MMU profile
Ok, I dissected the GCODE output from Slic3r and updated the scripts in S3D using what I believe are the correct settings for the tool change with Prime Pillar enabled. I did some slicing tests which seem to work, but there appears to be 2 issues preventing me from actually trying it out.
1. I can't center the model on the buildplate without adjusting things manually. Perhaps there's something in S3D that makes this easier, but the "Center and Arrange" button just makes all the .STL parts a mess on the build plate and not aligned. [FIXED] Grouping the .STL parts, then clicking "Center and Arrange" fixed this.
2. There seems to now be TWO prime pillars. I don't actually care about this one as much for the time being, but hey, seems odd nonetheless. [EDIT] Seems that the "second" pillar is caused by the unload/load commands in the tool change script and not part of S3D. Will need to figure out how to make this a bit more dynamic and relative to the S3D pillar.

Re: Simplify 3D MMU profile
There's a reason why there's a post-processor for MM use.
As for prime pillars, there should be one for each filament, but they will not be anything like big enough for the volume of purge required.

Re: Simplify 3D MMU profile
I used the GCODE that Slic3r exported for the unload/load/wipe sequence as part of the S3D tool change script which should help with the purge issue. The need for the post-processor should be diminished by use of the tool change script as well as the inclusion of the S3D prime pillar which is set for each of the extruders when used as separate processes for each. The only real issue is that there's two pillars (one for unload/load/wipe code from Slic3r and a 2nd for the S3D prime pillar) and they happen to be in different places on the bed, with the one for the unload/load/wipe being "fixed" in the same location as opposed to the dynamic, user controlled feature of Slic3r.
The pillar in the upper-left is the GCODE from Slic3r converted to the S3D tool change script, the one in the lower right is the S3D created prime pillar.
