It doesn't seem the problem is idler pressure, but, aggressive retraction settings, that make my prints look a lot better. I think that sharp teeth repeatedly hitting the same spot of the filament was grinding it.by ibpsrs - Plastic Extruder Working Group
I think it quite differently, sharp teeth will bring grip, but they have the terrible side effect of grinding the filament (see in the post below). Square teeth are better in this way. I found a problem with torx round teeth too: they need really high idler pressure, much higher than i thought.... I found another design, MoonCactus hobbed bolt, it is really easy to make with a dremel. He explaiby ibpsrs - Plastic Extruder Working Group
I've been thinking about using Torx drill bits, like theese, as an alternative to hobbed bolts. They are pretty much standarized (hobbed bolts are clearly not, I have 3 of them, 2 from the same supplier, and all of therm look COMPLETELLY different), robust, cheap, and a lot lighter (in weight) too. I did a bunch of manual tests and it seemed there was enough grip, better with ABS. Have anyone triby ibpsrs - Plastic Extruder Working Group
This desktop model is the only possibility for me (I live in an apartment...). It must be enclosed too, maybe, inside an acrylic tank, like those for goldfish, but with some sort of cooling. I also think I should start with a 3-axis hardware, skipping steps don't seem to be a good idea. I think is a good starting point, but I need to modify it.by ibpsrs - CNC Routers, Mills, and Hybrid RepRapping
Hi guys, I am looking for any open source 5-axis project, but I found nothing. The closest thing I could find was Mike Calvino's project on . I already know the biggest problem is the "slicing" software, it is a completely different thing with the 2 "extra" axis. I am a C++/Python/Java programmer and I did some C code for 3D sculpting in the past, so I think I can do It. I just don't want to foby ibpsrs - CNC Routers, Mills, and Hybrid RepRapping
