Just out of curiosity, is anyone using 1.75mm hotend ? I had a sidebar conversation with Sublime, and 3mm is the recommended filament size due to rigidity etc - retraction speed, feed thru bowden tube... I chose 1.75mm initially given I use that for my Prusa - one size for all my machines... I'm switching to 3mm to see what the results will be, but interested in anyone else's experience with the smaller nozzle diameter.
