my bulldog lite is working great with both hot E3D Abs that PlaQuote

I just wanted to post about my experiences with the Bulldog extruder.
I ordered it through their initial Indiegogo campaign, so I would have a good extruder for my new printer. Not sure if I got a lemon or what, but the extruder I received is a piece of junk. It doesn't have the strength to push ABS or PLA filament through even a basic .5mm hot end even at reduced speed, let alone the tighter nozzles that it included (Merlin and Magma). It fails to maintain a good enough grip on the filament to push it through, and when you tighten it enough that it ought to have enough power, it starts jumping gears in its gearbox.
I have a Wade's Accessible extruder on my old printer and I have never had a single problem with it. It works flawlessly. And so I am putting together another one and scrapping the Bulldog until I can get either a refund or replacement from ReprapDiscount.

look also the sharp curve in output
do not tighten the screws a lot of pressure otherwise the thread mill
