I don't Because quad bowden extruders with active water cooling is the new thing, right?  http://e3d-online.com/The-KrakenSpeaking of E3D, I've heard second hand claims at my local makerspace that it has issues with long running PLA prints, allegedly due to the stickiness of melted PLA and the lack of a PTFE liner. Has anyone else heard something similar?

I can totally see that (e.g. support material in a different medium, etc) and it's certainly a valid thing. I just have never needed anything more than one. I just found it noteworthy that their previous line and their experimental line of printers all had dual extrusion but this new generation has it nowhere to be seen.

My E3D hasn't had any problems granted my longest print was 7 hours. I've got another E3d coming with a bowden heatsink, plus a spare bowden heatsink to replace my existing one. Just need to finalize my dual design and get the parts fabbed. I hope the kraken gets the companion RAMPS board it needs and soon.

You also need thermistor inputs and heater outputs beyond the stepper controller. Edit: I see it has expansion boards. MickRaider fucked around with this message at 21:27 on Jan 7, 2014 |

Question for all of you that have a 3D printer (you lucky fucks). I think I am finally ready to get a 3D printer and I am leaning both towards a complete kit that I would assemble since I have heard some horror stories about people trying to source all the parts on their first printer, and maybe a RepRap style. I want to print in ABS mostly so I also want a heated bed. Does anyone have any recommendations for where to get a kit or maybe some other ideas? Anyone ever tried those cheap Chinese knockoff MakerBots? IndianaZoidberg fucked around with this message at 05:47 on Jan 8, 2014 |

There's also this guy: http://www.panucatt.com/Azteeg_X3_reprap_3d_printer_controller_p/ax33dp.htm In for a Kraken, I figure I was about to go down the dual E3D route and since they cost roughly $180 what's another $30 for two more heads in a more compact package?

Reason I didn't go with kraken was A) there's no models out there for me to design a new carriage B) the cost of buying a water cooling setup C) Software/hardware lacking That's an awesome card though. Now there just needs firmware support.

I'm planning on only running two extruders until I find the need for more.

My ideal kraken would be 1- Primary color .25mm nozzle for perimeters 2- Primary color .4-.6mm nozzle or larger for infil 3- Secondary color .4mm nozzle 4- Dissolvable - .4mm nozzle Though I'll be happy once I get my bowden heat sinks and second E3D to get primary + dissolvable. Speaking of, does anyone have a good source for dissolvable filament besides makerbot? Their lead time is awful. MickRaider fucked around with this message at 01:29 on Jan 9, 2014 |

Having used a water cooled PC I built for several years, the combination of water and electricity doesn't phase me as much as it should. The computer doesn't have to move, for one.

Cockmaster posted:Would the Arduino Mega CPU be able to handle all that? I had heard that the existing firmware was pushing the limits of the device. According to the reprap forums thread it should work with the Due (a 32-bit ARM Arduino). There's also the RAMPS-FD (RAMPS For Due), ETA sometime in March, that should be able to drive 6 extruders together with an expansion board. Looking forward to these because I have a quad-core UDOO board waiting in a box.

There's a few things existing software can do to squeeze more out of them. First would be to use straight C/C++ instead of the hybrid Arduino language. Some of its commands are ungodly slow, usually anything involving IO. Next would be to modify the slicers to work in micrometers instead of millimeters. This would allow the chips to run pure integer code, as the Atmels don't support native floating point. Past that, take a page from the repetier-firmware playbook and use a binary protocol. It would cut down on string parsing the micros are doing.

It wouldn't be $10m*, probably $2-4m. And it will probably have a reduced lifespan compared to a normal machining center, I know laser welders wear out fast. The programming is all G code. That won't go away for a long drat time. It works well enough and it's completely ingrained in the industry. *Unless you want more than 128Kb of memory.

Would this be the right place to ask what affordable CAD software is available to use to 3D printing? I'm a mechanical engineer and have plenty of experience using Solidworks which is overkill (and prohibitively expensive) for what I have in mind. I only need to make or manipulate solids; no need for manipulating assemblies (though it'd be nice to have), drafting, or FEA simulations. Any suggestions for something cheap (<$100) or free that has similar functionality in creating geometry and solids like Solidworks? Gotta save up if I want a 3D printer for myself.

Any suggestions for something cheap (<$100) or free that has similar functionality in creating geometry and solids like Solidworks? If you've got a .edu email address laying around you can use all of the Autodesk products for free, or Solidworks for pretty cheap. If you don't have a .edu email address around, you can get Autodesk Inventor Fusion for free. It's pretty alright for doing mechanical stuff. Not as powerful as Solidworks, but that might just be because I've had more playtime with Solidworks. It'll do dimensions and extrusion properly, and it has all of the basic geometric tools you need to print things. Blender is supposedly getting better for printing and actual CAD work, but I can't get myself to use it. I think they added a "3d printer toolbox" that has dimensioning tools in it. There is also the Autodesk 123d toolset, which I guess is supposed to be for "Makers," it's free. I personally have used 123d Design a couple of times, and it was a painful process. A lot of people seem to really enjoy working with those tools though.

The five categories are Sharpness, Distortion, Intersections, Thickness, and Overhang, and all of these settings are adjustable. For instance, the default setting for Overhang is 0 to 45 degrees on the negative Z axis. You can choose to play around with the axis depending on how you're going to print them out.

Full Spectrum Laser is doing a 3D stereolithography printer: http://www.kickstarter.com/projects/fsl/pegasus-touch-laser-sla-3d-printer-low-cost-high-q?ref=live I guess it makes sense - nothing new on the hardware front, it looks like a clone of the Form1 - but their "thing" is nice software/drivers. As an owner of a laser cutter with an "our CAD+driver software or nothing" setup I can appreciate the value that provides. But then again laser cutters =/= the software ecosystem that 3D printers have right now.
