After getting my stealth broken fuse replaced to fix the no power situation I was able to get into this some more today. I think I found the "secret" to making this beastie work properly with S3D... ignore the profile provided by KnP and just use the one for Makerbot 2X. This makes the heated bed work properly, gives full control over individual extruders, and opens up the build area to the full 225 mm width of the build table instead of the advertised 150. DO NOT waste your time trying to import and make the KnP profile work. You will just pull out your hair.

My one remaining issue is the left extruder nozzle is too high. Not so high that the filament wouldn't stick to the table but no squish at all so the bead is high enough for the other nozzle to hit the print and ruin it. I backed the nozzle out a fraction of a turn and was able to print successfully with the left extruder but not ideal to leave it loose. I need to figure out how to adjust it properly. Maybe tomorrow.
