Hi all, I'm super excited with the first batch of prints on this machine (my only prior experience has been Monoprice Select Mini).
I'm printing a few of these spools http://www.thingiverse.com/thing:1996247 to split 1kg filaments with my friend.
I first started with 50mm/s print speed and 0.2mm layer height, then mid-print bumped up the speed to 75 then 100 and its fine!
Note that I still left these speeds to the default in Cura:
Outer Wall speed: 50mm/s
Top/Bottom speed: 50mm/s
Initial layer speed: 30mm/s
100mm/s means the 3hr 5min print estimate at 50mm was down to 2hrs (since outer/top/bottom/inital was still slow as noted above).
This is gamechanging for larger structural/functional pieces where fine detail doesn't matter much.
