Re: [MakerBot] Replicator 2/ Replicator 2X - using 3mm filament?

[Mark Cohen]

It can certainly be done, but you would need a new pusher and nozzle
and adjust the software. I don't recall seeing anything on
Thingiverse. Most people want to go in the opposite direction. It
sounds like you don't have one of these machines, so why not just get
an Ultimaker?

+100 or get any other bot, maybe even get an old T-O-M used and have
me upgrade it to the U-T-O-M.

To be fair and try and give somone an option. You might, in a very
experimental way, be able to use the latest 4.5kg/cm nema 17motor from
QU-BD, with a printed MK8 upgrade parts for the filament drive whihc
will accept 3mm filament (I checked). Then the hot end needs the
current stainless thermal barrier tube replaced with a brass 3mm
version from Makergear and a matching Makergear nozzle. See the
current system butts up the MK7/8 nozzle by threading it into the
heater block ( it's all M6 threads). By using a longer thermal barrier
tube (although it would be better if in stainless) running that all
the way through the heater block and then screwing the female threaded
Makergear nozzle on top. Make sure the nozzle is tight against the
heater body while at the same time, the tube was bottomed into the
nozzle. Then all that threads like normal into the aluminum bar mount
on the motor. It might work, who knows. You need the high torque to
have enough pressure to extrude 3mm though and the MK6 had about 5Kg/
cm and I could get it to skip under certain conditions so we may be
right on the edge of working or not with 4.5kg/cm
