long, thin teeth equals eating away filament - no good in my opinion. It took me a while to get optimal results. The key things are big enough teeth and grooved idler - check my project: it's a bit messy so just follow around my conribs and thingi pages for more info.
shape of those teeth prevent to deep, khem.. you know what -

with only heat from the bed I got to 50-60C within chamber and you could barely feel heat coming out of the upper and side slots ("plastic melting smell" zone is also reduced - 2-3m vs 30cm from printer). I guess it's due to absence of holes in the bottom of the chamber so no place to suck cold air from and no convection. The is always an option to put rubber seal - lip like contraptions within t

I finally cleaned up files enough for a decent release. so enjoy and feedback me plenty.
it's cheap to make and comes with chamber as standard with no additional cost ;p

Hi, time to show what i came up with after some strange experiments ;p
so i prefer to actually put some PTFE for "lubrication", but it's a mate of one element and you have true all metal (tested by a friend).
It's quite reprap and rep-strap friendly - just a simple aluminum interface, piece of plate
Most important thing is, that single pipe goes all the way from cold to hot. No place for

I had the same idea and will probably go into experiment stage next month so feel free to drop me a line if you want to cooperate/share ideas

be more specific. it's like flow o water or current. you have to know(measurements, design, common sense ;p) from where to where it's flowing. the easiest answer would be just the amount you put in but i guess you are interested in some specific part of the circuit. It would be best to explain it visually.

I actualy designed and RepRap printed one.
though it's not realy considered to be a weapon by the law.
HUKACZ
but there is another funny thing, law actually fails to describe some kind of weapons precisely. In Poland you have to have a permit for a Brass_knuckles. But where this weapon begins and large keyring begins no one knows. It'a actually no problem to print it.
I actually am in conta

stainless steel or better titanium alloy work great as heat barrier as long as you keep the walls thin. or make bigger heat sink - but energy goes into space

it's pretty straight forward but i will post some better documentation along with other golemD files.
soon a polish forum friend should make some test on a ABS carriage printer with aluminum p

So, I completed next golem to a near GPL publication lvl. Two units are up and running almost 24/7. One printing competition was won (yay!). It seems as stiff as conrete casted ones what do you think?
Dibond /aluminum-pcv-aluminum/ is faster to assemble - premilled bending lines - but you can make a box out of plywood or cast it like golems B and C.
Dibond files are openSCAD generated. I inten

that's what params are for. move the motor as you wish to suit your needs. this stepper position was optimised for Mendel, at least i hope so, since it was feedback based from betatester. i use different params for golemC, but it was pointless to publish them without the rest of parts.
dont't steal, modify the code! loose the carriage foot, add whatever mount you need and give others to enjoy

work's quite fine. in reality it only needs to adapt about 0.3mm for combined filament and drive screw inperfections.
yes, only about 1/3 of the pipe circumference is under tension, but the rest helps keep it in place
in elevated temperatures PCV will become soft, so black rubber would be better. or no tensioner at all, just constant spacing (far less fail safe)
you can change the pcvbearing

i was never satisfied with just copying, so had to make one different. perhaps in some way better, or just will inspire someone, check it out, give opinion.

doesn't weight more then my old laser printer about 15 kg (below 30 pounds).
this one is casted, but it could be printed with concrete for example.
such printers exist already. I have to build one too!
well, I do have a wobbly isue... the whole table is moving! had to decrese speed and acceleration, need more sturdy furniture.
