I have tweaked and refined the BigBox Dual S3D Profile. Before I pop it onto the wiki it could do with a little testing! It will work just as well for both dual and standard printing, no need to use different profiles. In fact it will work for the Pro & Lite machines too, but there would be little point to that! If you're interested download if from | https://www.dropbox.com/s/zp7fcd50eam1qxz/Dual 1.1.fff?dl=0 Please make sure you have followed through the updated and now complete commissioning process. I have added in nozzle alignement, nozzle levelleling, extruder offset and mesh bed levelling instructions. To get the full effect you'll need to have gone through all of those processes | http://wiki.e3d-online.com/wiki/Printer_Commissioning#Dual_Nozzle_Alignment Any problems, comments or suggestions please post here.
