Ok I gotta know about Bill Nye. I have heard him interviewed before and definitely got a whiff of arrogant dick. What specifically was it?

Ok that out of the way.

Yay BB coming back. Just hope ABC don't sanitize it so much it loses its appeal/

no it doesnt. that is a modified version of the real old filament drive. all the prints i have ever seen of this model doesnt have those wall connected. i ran one like this for quite awhile Obviously I am printing this in prep of my new M2 however the fact you called it a very old version of the dr...

are you talking about the outer wall of the round part where the main mounting bolts go? if so it is because the wall thickness in that area is thinner than you extrusion width setting. s3d knows your nozzle width and what can be printed and what cant. kisslicer may slice it ok but it wont be withi...

Can anyone tell me why S2d wants to slice this http://www.thingiverse.com/thing:37774 model with a gap in what appears to be a solid wall where the hex bolt should go. I am attaching the gcode here. KISSlicer does a decent job of slicing it but for some reason hates the PET profile I set up there, d...

Its really not that big of a hassle. It's printing 1 part, undoing 2 screws, removing the old part, installing the new printed part with the 3mm hotend. Then set the filament diameter in your slicing software to 2.85mm (or whatever you measure it to be). I honestly believe it took me longer to find...

This was a hotly contested topic on the Makerbot group when they announced the switch from 3mm to 1.75mm with the Replicator series. I'm still split on whether or not it was the right choice... I get the physics argument that 1.75mm = 41% less material to extrude and subsequently have to try and re...

Thanks for the info. Ultimately I would like to replace the hotend with an E3D version but I think you might be on to the best solution whereby I ask for ABS filament instead of PLA and print up the 3mm part in that. For the sake of 65 bucks I think the prebuilt 3mm hotend is the way to go. I am gla...

I am currently looking at new printers and the M2 is obviously high on my list of choices. The one sticking point - 1.75 mm. I am currently sitting on quite a large stash of 3 mm filament - some of it quite expensive and specialty. In addition I feel that 3 mm is overall a better media (cost etc). D...
