Itty Bitty Double FLEX V2

[clough42]

In the process of building it now - soldering is going slow because I keep getting interrupted...

Question, if the nozzles are about 26.5mm apart is this ok or do they need to be exactly 27mm. Is there some way to calibrate the difference in Marlin?

They don't have to be exactly 27mm. You can calibrate the actual distance in software.

You can do it in Marlin, but I find it easier to manage in the slicer. I've done it in Slic3r and in Simplify3D, and that's what I recommend.

Instructions for calibration and a calculator to help are here: http://clough42.com/instructions/dou...r-calibration/
