My build is progressing well and after some confusion with temperature calibration I got onto trialling the benchy. Not done yet but my hat is off to any one who has achieved that at 0.2mm layer, 0.4 nozzle in PLA with no part cooling fan. I've the .2 kit which came with the place to mount the fan, but no fan.

I have up and added the fan. Adding it turned the 3DBenchy from impossible to possible!

Any Pictures?

Any advice on how to do temperature calibration?

What slicer do you use? Any chance of sharing Slic3r settings?
I spent a fair amount of time in drawing up a spreadsheet in order to completely document and plot different settings against each other.
I am willing to share it with the comunity and we can add on to it.

I am looking to implement a Cobra Type fan for my printer.
