I'm looking to replace the extruder on my #Prusa i3 #reprap. Almost every part of this extruder was printed on this printer. I want a replacement that can do 1.75mm filament. I don't need awesome performance, or lots of bells and whistles, just something reliable and repairable.
My shortlist is a voron stealthburner, prusa nextruder, or an E3D roto. Any suggestions?

I just need to take it easy (and sleep a lot) for a little while, then I’ll be back on the project full-time!

With so many changes in our industry, now is Marlin's critical moment.
Our sponsorship is in steep decline, yet our workload is holding steady.
As we continue support and development we need your help now more than ever!

A recent project of mine has been to install a heated bed on my #3Dprinter. It went quite smoothly and it improved quite a lot the warping when I print #PLA. I used a solid-state relay that is kept in the bottom of the printer, inside a small box that I designed and printed myself. The results are very good! The warping is clearly reduced. It is not shown, but the wiring also contains a protection hearth wire for the aluminum plate. #3Dprinting #DIY #RepRap
A new version of Auto Build Marlin just dropped with more useful improvements.
- Update the Config Editor for compatibility with Marlin 2.1.3-b3.
- Add Documentation Search to the Info Panel for easier access to the information you're looking for.

Marlin 2.1.3 beta 3 is out now! https://github.com/MarlinFirmware/Marlin/releases/tag/2.1.3-b3
We're in the home stretch to the official release. One more big sprint to address all your outstanding bug reports and then we'll put a ring on this thing!
#HotTake A second hand #3dprinter (open source variety) is worth more than a new one. I have a second hand, well aged #Ender3 and I wouldn't have change it for one straight out of factory if someone offered to swap. I got it modded, added some tiny but significant mods myself, like a kapton tape in some strategic places or a direct deivinator. It's a much better machine than a new one. It is worth more than a new one to anyone with a brain. I got it for 2/3 of the price. It's a steal. Buy used 3d printers, it's really worth it, they are immortal. Ofc I'm not talking about those closed sourced, gated bs machines. I'm talking about the good machines originating from #reprap ecosystem and project.
Wow 17 years already, time flies! Thank you Adrian, for your invention and all your hard work

Hark! The beta testing period for 2.1.3 is almost over! We’ve been cleaning up, revamping, and optimizing the motion system to achieve higher acceleration and fix longstanding annoyances. Your existing #RepRap machines and #3DPrinters will seem brand new, and your future builds will be extra extra.
Tomorrow (29th May) is RepRap Day. On that day in 2008 we announced #RepRap, the first replicating #3Dprinter as Open Source, and kicked off the home 3D printing revolution.

I don't suppose anyone in or near #rdguk wants a #reprap #3dPrinter ?
I built mine years ago, and I've barely used it since. It worked well, last time I used it, but it needs a bit of fettling if you want to print over the whole bed area (there's a bearing mounting that needs to be printed and fitted).
Community, DIY, open hardware and software has been part of the commodity #3Dprinting world for over 20 years (#RepRap et al.). Open projects, with parts you can source yourself or via kits (e.g. #Voron).
What if—what IF!
We did the same for plain old #2Dprinting..? I’d build a 2D laser printer from a kit.
(To be fair, I found a few resources and it seems like a daunting talk: lots of moving parts, optics, etc. 3D printers almost feel simpler, they’re just robots that push out hot plastic.)

(and toner/ink DRM, etc.)
A une époque, il y avait des imprimantes 3D comme la #reprap qui essayait d'être #openhardware ou reproductible ...
Ca existe encore ce genre de projet ?
