I've had my duo for a few months. I've been running ultimachine black ABS, natural HIPS, and a gray PLA sample they sent me without issue. I've also been using the yellow and red/orange samples that came with the bukobot. Are they diamond age from printbl?
Last week I received a 1kg roll of sapphire PLA from PrintBL. I've made around 20 attempted prints. Only one has completed correctly (an iphone case).
I'm getting excessive extruder clicking/skipping to the point that it isn't putting out much at all, but it only happens on thinner walls.
I've tried temps from 170 to 210. I've also tried slowing down the print speed.
I've switched to the second extruder hoping that would help.
I've disassembled the extruder and tried to free it up a little (assuming too much drag).
I've increased the voltage to 13.8 with the trim pot on the power supply. I have not tried reducing it below 12.
I've removed material from the plastic piece the locking lever rests against to reduce the pinching force on the filament.
My other 3 pla filaments work fine. Any suggestions would be greatly appreciated.
