I keep hanging on to this 2010 era cupcake... Because it's cool, and my first 3d printer and I'll get around to it some day! And I think we can now say it's retro cool I'm recently realizing my need for a quick prototype printer - something to use to verify designs as I go. You know those it looks about right but let's print an outline and see if it actually fits the space moments. Spend halfby hephaestus - Let's design something! (I've got an idea ...)
Quotebobc I am currently testing a 3 extruder board for Arduino (RAMPS-FD ), and soon a 6 extruder extension board (EXT6 ). So that is 11 axes and 1 extruder, or 3 axes and 9 extruders depending on configuration, or any combination in between. So if anyone wants to build a sextupteron, I would be happy to provide a beta board and firmware help, in order to help development. You would need to proby hephaestus - Delta Machines
Its going to require some lean code, there's no doubt, but I've got a bright shiny nickle that says its doable... Nuvoton has a couple LQFP package units, that are interesting, given they appear to be 5v tolerant, at least by the data sheet / vdd...by hephaestus - Next Wave Electronics Working Group

Not so much I want a breadboard, but it makes a nice circuit testing environment prototyping on the breadboard makes it quick to test and get onto the software side... I've said it before, I want a cortex AIO, with user replaceable drivers... so I don't brick a full board with a driver issue... I was starting to play with a drawing to make a cortex a drop in replacement for an atmega644/1284by hephaestus - Next Wave Electronics Working Group

Nope I'm anxiously awaiting sango-bc But I also realize DIP components are much easier for many of us (Especially me, I'm not good at fine soldering; I can barely do DIP some days) Luckily I have access to some toys... I was just pondering how hard it would be - to make a 'daughter board' with the LPC1114FN28 - so it plugs right into the Gen7, in place of the ATMEL... add a 3.3v regulator, anby hephaestus - Next Wave Electronics Working Group
Someones gotta be voluntold Nothing against the current arm designs, but they're designed to be factory built, and non replaceable drivers can make a board useless fast... and DIY is better Edit, no I don't mean to sound like that I'll happily give it a whirl, but I'm no EEby hephaestus - Next Wave Electronics Working Group
OK, so the question is, who is starting the Gen8T design? and who's crazy enough to start porting a firmware?by hephaestus - Next Wave Electronics Working Group
Measurements at 90deg to each other and compare? Hadn't pondered out of round, will have to go chase a hunk of that roll down and check.by hephaestus - Controllers
Not to take away from r2c2 - but for hackers who like to play and not have all-in-one boards (stepper drivers blow), or 4pi or any of the other projects... Teensy 3.0 started shipping: Maple mini's looking fun And found this interesting maple mini Reprap controller project on github -by hephaestus - Next Wave Electronics Working Group
I'd tend to agree, however for some of us who order cross border - it gets ugly... This rolls half done, and suddenly running into 15% variation along a foot - makes it hard to get tolerable prints. (And no, it's not a cheap roll, yet I've measured 2.78 to 3.09mm diameter - within a 300mm section) We know there are manufacturing discrepancies, seems to happen with all suppliers, so is it betterby hephaestus - Controllers
As I sit here cursing and swearing, filament that's got more curves than marilyn monroe... I'm wondering - do any of the firmwares have support for a 'on the fly' measurement of the filament diameter - with capability to automagically adjust feed rate? I was thinking along the lines of passing it through an IR beam just above the hot end and working back to a diameter, but there's probably soby hephaestus - Controllers
Well here's the outright just of it... eventorbot -enlarged and stretched a little (should be good for 18"/450mm travel on xyz). That's +/-1000mm of belt for x/y belts, I don't think that's so workable even some rough tests with some 12mm belt I have lying around - that's a lot of play... Was leaning towards NEMA 23 steppers to avoid the not enough torque issue, yeah means more headaches in elecby hephaestus - Mechanics
I know its discussed fairly regularly... Can we spin it a bit? Yes acme lead screws are expensive (I have a freebie source) and slow... It's that slow part that has me pondering... Perhaps you mechanical wizards can help me hash it out? It's the slow speed thats usually referenced as to why acme leadscrews aren't used - great accuracy, slower than sin... I'm wondering - what if instead of direby hephaestus - Mechanics
