We've had the F306 for 3 weeks, run through 3 spools of PLA (1 in the first 3 days) - so far it is a very promising piece of equipment - the next generations will be awesome, as this first gen is on par with developed tools in other industries (we develop parts for historic Porsches)

look for extruder fan issues (small batch of 12v fans delivered instead of 24v - we were lucky enough to get the 12v, so a replacement is on its way) - that is the only possible flaw we can find as of yet, and we've been running this thing round the clock, hard.

best $ we've spent in a long time.
