Re: How fast can a Gen 3 Electronics Print? - 14 years ago

Re: Bottom Feature - 14 years ago
The documentation included with skeinforge is always up to date. QuoteAdditional Height over Layer Thickness Default is half. The layers will start at the altitude plus the Additional Height over Layer Thickness times the layer thickness. The default value of half means that the bottom layer is at the height of the bottom slice, because each slice is made through the middle of each layer. Raft eby NewPerfection - Skeinforge

I started with a 0.5 mm nozzle, but switched to a 0.35 mm pretty quickly.

Re: what extruder speed is needed? - 14 years ago
15 mm/s will be ok, it's a bit slow but won't be too bad. I print at 25 mm/s, limited simply by my bed being too heavy so if I run faster I skip steps. I run a 0.35 mm nozzle too, so with a 0.5 mm nozzle at 15 mm/s you'll be fine.by NewPerfection - General
Re: I'm confused Reprap vs Makerbot - 14 years ago
The "official" RepRap electronics are equivalent to the MakerBot Gen 3 electronics. I say "official" because there are many options, and I believe there are better options. I use RAMPS and it works great. Gen 6 or 7 are other options.by NewPerfection - Controllers

Re: Change host to use E_STEPS_PER_MM of feedstock rather than extrudate? - 14 years ago
Just set your extruder feedrate in Host much lower, something like 150 mm/min, then use the extruder tab as normal.by NewPerfection - RepRap Host

Re: Screw drive to push filament? - 14 years ago
patbob Wrote: ------------------------------------------------------- > Now to see if I can adapt it or use some concepts > from it... One problem is that it rotates the filament, so the filament spool needs to be able to rotate in two axes. Also, it is slow extruding and difficult to control accurately without an encoder, and is somewhat complex. These are the reasons the move was madeby NewPerfection - Plastic Extruder Working Group

Re: Where can I buy makerbot extruder tips? - 14 years ago
Pick one of the $75 SuperPacks, with whatever nozzle size you want. I would recommend 0.4mm for starters. Then pick a wooden mounting piece that corresponds with whatever extruder type you are using. Rick is extremely helpful and will answer any questions you have, you can contact him via his IRC channel or the Google group, both of which are listed in the left column on the site.

Re: Axial fan blades - 14 years ago
Yes, as long as the overhang isn't beyond 60 degrees. To do that requires a well tuned bot though. But it definitely would be possible. Using support material could work as well.by NewPerfection - General
Re: Where can I buy makerbot extruder tips? - 14 years ago
MakerBot Industries has them custom manufactured, so unless you want to take their drawings and have someone else manufacture them for you, you're out of luck. May I suggest MakerGear for hot ends though, I use one of theirs and they are extremely reliable.by NewPerfection - General

Can't a solid mobius strip be designed with just one outer surface?

All with reasonable shipping costs too. is always good too.by NewPerfection - Reprappers
