Have you tried asking the manufacturer to see if they are already using S3D with their printers? Maybe they already have a profile.
Otherwise, I would just pick an existing profile provided by Simplify3D that is similar, and then just customize it for the BCN3D. For example, choose the "MakerGear M2 Dual" and then change the machine settings and scripts to your liking.
And of course, once you are done, it sounds like others would love to use that profile too (so maybe post it on here)
