I just wanted to show the quality of parts, ORDbot vs Reprap.
Disclaimer: Now obviously, there are setup differences and the files aren't exactly the same, but you get the drift. The black parts are printed on Jeremys ORDbot, the natural ones are printed on a reprap by an ebay seller. Jeremy did these for me before he further tweaked his machine, so I bet his results are even better now.
First, the big gears.
As you can see, the black gears are nice and smooth, with the actual teeth very well defined. The black parts teeth are also "square" to the face, while the natural parts are shifted slightly.
Next, the small gears.
The black part has well defined teeth, and you may notice it actually sits flat when placed upside down. The natural part is shifted a bit.
Next, the main extruder body.
Notice how clean the edges are on the black parts. I just need to drill the holes for the motor and the pinch bolt, and it's ready to go. It's hard to tell, but the natural part bolt holes are basically unusuable without serious work, while the black parts allowed the bolts to drop straight in.
Finally, the bearing holder.
It's hard to tell from the picture, but the filament guide on the natural part is shifted, rendering it useless. Also, I could not fit the bearing in, while it snapped right into place on the black part.
I think the ebay seller has some more tweaking he has to do, as most of the parts were shifted slightly, so that could be due to a heated bed, warping, etc, I'm not entirely sure.
Overall, I am very impressed with the black parts that Jeremy printed for me. I just wanted to say thanks again, and I can't wait to get my Hadron so I can start printing stuff like this!
