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!
