 *** 220°, 110% flow, print @ 30mm/s (1/2 speed), travel @ 60mm/s (also 1/2 speed), 0.4 mm nozzle size, 2.85mm filament size are the '''safe''' settings for this printer.
 *** Excellent results have been reported using 220° & 135% flow. '''However''', anything above 110% flow makes head jams more likely. (Some filament reels will work @ higher flow, while others constantly jam.) Thus reducing both print speeds is sometimes a better answer than increasing the % flow above 110%.
-*'''Filament Loading Problem''': the printhead is all misaligned, specifically the PEEK peice (light brown in colour) to the teflon coupler (white in colour) above it. Trying to push filament through there to the nozzle is difficult. Try to make a long and sharp point on the end of the filament, the longer the better, so it gives plenty of space to wiggle around in when shoving it in. You can see through the tube going into the top of the teflon piece, so use that to judge how far down the filament has gone. It probably helps to have the nozzle hot, but don't keep the nozzle hot with no filament inside because it is likely to burn plastic/dust inside the nozzle and cause friction issues.
+*'''Filament Loading Problem''': If the filament is in the Bowden Tube while putting that back into the Printhead, then expect problems getting it properly aligned and loaded. (Pull back the filament, insert the Bowden Tube into the Printhead, then reload the filament.)
