Neat. You held the phone for 15 min? So with the input shaper on are you happy with it overall or think it's under baked right now? On functional parts do you foresee yourself using it? The Bonker's benchy seems more of wishful -thinking- printing vs usable print.
Honestly, with the default 0.6mm nozzle, this thing is already pushing out plastic as fast as the current hotend can melt it. and the poor layer adhesion on this first print is strong evidence of that. What this thing really needs is a High flow nozel design so it can actually make proper use of a faster motion system.
