Re: Hom Many 3D Printers Do You Think a School Should Have? - 8 years ago
QuoteLoboCNCAlso, there is a huge advantage to having all the printers be the same, both in terms of teaching the kids to use them and in dealing with maintenance. I agree with you, but I think there are also benefits to having the printers be different. For whatever reason, people tend to be inflexible at times once they learn and become comfortable with what a certain thing is or how it operaby Melty - General
Re: No-leadscrew, single-motor, precision Z-axis design - 8 years ago
Quoteo_lampe Quote Looking at the top diagram, if the bed rotates about +Y or -Y, the vertical cables will attempt to pull in towards the center of the carriage. Since the cables are under tension, this will be resisted and there is no rotation. To rephrase, any rotation should increase cable tension. The cables at the side only increase their tension when the rotation force is in CCW directionby Melty - General
Re: New Genuine J-Head™ 10 - release! Finally a Bowden J-Head! - 8 years ago
QuoteValduare there are bullet points on as well as a datasheet There are, but neither are particularly helpful when comparing your hotend to the competition. If you think you have the winning design, make it clear why it is better. At best, all we can gather from the website is that the J-Head 10 is better than the prior J-Head. And the data sheet... has a mechanical section with no dimeby Melty - General
Re: Simple board comparison - interactive - 8 years ago
Looks incredibly useful! Nice work! A few small suggestions: * For the Smoothieboard, you might specify that it's the "Smoothieboard V1" in case they ever do finally manage to release V2. Also, there are the 0x/3x/4x/5x variants of V1 with different numbers of stepper drivers. * For the "stepper drivers type", some of the boards have that field populated with an interface ("Polulu"(Pololby Melty - General
Re: New Genuine J-Head™ 10 - release! Finally a Bowden J-Head! - 8 years ago
Hey Valduare, instead of wondering why they aren't more popular, how about giving a set of bullet points for why a person should choose a genuine J-Head as a hotend? hotends.com is just a page of buzzwords and marketing speak... If you didn't already want "a J-Head" before going there, there isn't any info there to convince you to buy one. There's very very little to clarify why the more expeby Melty - General

Bug Reports for Slic3r AND Slic3r PE? - 8 years ago
Quick question: In this post-fork world, where is the preferred location to post bug reports for issues that are common to both original Slic3r and Slic3r Prusa Edition? Some tangential questions, or perhaps the same thing asked differently: * Does the Prusa team monitor and incorporate bug fixes from the original Slic3r codebase? * Does the original Slic3r team monitor and incorporate bug fby Melty - Slic3r

Re: Filament recycling/making system for home usage - 8 years ago

Re: Does marlin BEEP when 3d print is done ? - 8 years ago

Re: Does marlin BEEP when 3d print is done ? - 8 years ago
I've often wondered why both Marlin and the slicers don't all have an option to "enable sounds" for various events. For example, if I turn my kitchen oven on and set it to 350, it will beep when it is preheated to 350. If I then change the temperature to 400, it will again beep when it hits the temperature. It would be awesome if Marlin did this, with a unique tone for the bed and extruder.by Melty - Firmware - Marlin
Re: Filament recycling/making system for home usage - 8 years ago
But I think that's the core of the problem... Even at "just" $300, the payback period with raw pellets is still rather long for a home user. And the dropping prices and widespread availability of ready-to-go filaments for $13/kg or less haven't helped... Not trying to be pessimistic - I'd love to find a solution. But to do MORE than the Filastruder, and to make it economically viable to proby Melty - General
Re: Filament recycling/making system for home usage - 8 years ago
Quoteorbitalair I would appreciate a way to recycle my pla and abs. The current price of $500US for a setup is too expensive for me. Also helps to be small as possible and space saving. Wouldn't the benchmark system be the Filastruder - $300US ? I too would love to have an affordable way to recycle my plastic scraps...by Melty - General
Path randomization for identical layers? - 8 years ago
Does Slic3r have a feature or mode where you can intentionally randomize the per-layer print pattern for vertical stacks of layers with identical geometry? I've been making some prints with thin features - taller vertical cells with single line walls... sometimes two-line walls. What happens is that I'm getting compounding failures, where an issue in one layer takes away the starting point fby Melty - Slic3r

Re: Terminology: "RepRap" that can't print itself, but CAN print others? - 8 years ago
QuoteMKSA BTW, did Melty the OP got his answer ? No, not really... I think the influx of cheap printer kits and printable upgrades has caused a disconnect between "self assembled printers with some printed parts" and the core mission of a RepRap - being as close as possible to being self replicating. For example, the metal parts... extrusions and brackets... those are 'vitamins' in RepRapby Melty - General
Re: Beacon 3D Printer - 8 years ago
Ahh, yes, I had forgotten that most of the inexpensive kits are based on rods instead of rails. And once you get to a kit substantial enough to use linear rails, you're going to be spending quite a bit more, and still not necessarily going to get four of them like your design requires. Ok, nevermind on that then.by Melty - General
Re: Beacon 3D Printer - 8 years ago
Is it the weekend yet? This may be one of those interesting designs where the most economical way to build it is to buy a full kit for a different printer, then just use those parts as the vitamins for this one. Sometimes the generic 2020 i3 kits or the like can be a pretty good value for the components, and you save a lot by buying all of the items together at once instead of shipping a bunby Melty - General
Re: Beacon 3D Printer - 8 years ago

Terminology: "RepRap" that can't print itself, but CAN print others? - 8 years ago
Something I've been pondering: What would you call an open-source 3D printer, made of printed parts, but which for whatever reason CANNOT PRINT ITSELF? Would this still be called, or be able to be called, a "RepRap"?
