You might be right? I had wondered how the open source model produces money for people to live, there's certainly a lot of work, time & effort put into many great developments, but how to survive without selling something in the end, I have given away most of what I've produced, but I made that choice, for some free bandwidth on youtube, or use of a blogging platform, but sooner or later youby MechaBits - RepRap magazine
it wouldn't be any heavier than a granite chopping board, slimmer but longer 1" thick, simple, functional, the only problem I see is shipping it, I would rather a simple light mold that could be used to cast a resin base...add some broken watch parts, fossils, old computer parts or what ever. But as for using as a heatbed?, but I do love a nice juicy steak served on a hot slab of something.by MechaBits - General
Not thinking about moving the first build, figured a heavy base would provide a stable base less prone to vibrations, no need for frame, single Z would have a smaller footprint but if dual Z would need a base about 150x400 so quite slim.by MechaBits - General
QuoteElmoC QuoteMechaBits Not that I dont want heatbed, just first things first, without so as not to fry anything in the arduino too early on, I wouldn't mind using a slab of granite or concrete for the printer base, if I can set some M8 or M12 inserts in it. Are you serious about the granite and concrete or not? I was talking about base not bed, if i had a heavy base, with holes for rods, orby MechaBits - General

Not to mention negating all the weight saving you might have done, but I saw an interesting chopping board the other day, made from some plastic material with swirly grooves in it, and I wondered could this be like the printbite stuff? might be good for cold bed with pla? Though I got a 200x200 tempered glass square for 99p from Home Bargains, its gotta be good for something.by MechaBits - General
Dont forget the solar ones too, I'm sure if I had a mill I'd need more quality tools, but a healthy mix of digital and analogue dials, I found a micrometer in a shop the other day, but thought do I really need it when i have the calipers, but couldnt think of a good enough reason for having them except nostalgia, and the love of craftsmanship.by MechaBits - General
Yeah in use every day battery still going strong. Which is more than can be said for my Ph testerby MechaBits - General
and digital vernier calipers where not invented by Pierre Vernier, but they are good enough, unless you want old school.by MechaBits - General
That's funny I'm sure mine where from Lidl too, Powerfix Digitaler Messschieber, no mention of china anywhere, so possibly made in germany? If you want to see if Lidl have them you might have to walk over the road, looking from afar wont help or on-line, there's always a few surprises in the tool section.by MechaBits - General
I got a cheap one, it's great!by MechaBits - General
Ah I see, sorry bout dupe, filament could bend a little, deviating it from the hole, but maybe that cheap one could be modified with a little throat, I also have a different grooved drive cog.by MechaBits - General
Anyone tried this extruderby MechaBits - General
2 trains of thought at the moment, one rotational the other linear, the linear one only needs to move 0,9,18mm(though doesn't matter too much if its remote), just a simple dovetail block. The other rotational one, could be belt or direct, so i tried direct first. Wondering if I need to add a blade, or if retraction would be enough, also with a tendency to make things more difficult than need bby MechaBits - General
I've only been playing with this design out of boredom, I know other solutions will appear long before I ever decide to build a multi extruder, cant see me wanting multi colour anytime soon, but this looks like an interesting development, a little large & price might be a shocker though. But a simpler colour wheel gate could be used to feed a bowden tube, i wouldnt mind some nice greyscale pby MechaBits - General
Thanks for the input guys, Sounds like trouble which ever way you go, but one nozzle with switching feeds sounds like the goal, dont have the worry of the other heads getting in the way, (I wondered how the positions of those would be mapped out in the code to avoid things?), maybe another nozzle dedicated to support material, one keeps things smaller & maybe cheaper, but agreed not with allby MechaBits - General
Wondering if Aerogels/fabrics could be the ideal material to help create a new extruder or modify existing ones, is this the fabric currently used to wrap hotends? Certainly help to save a reprap from melting.by MechaBits - General
Reminds me of the heatsink on the new LED light bulbs and the tripple headerby MechaBits - General
Interesting, seems like the fins would cool the hotend wonder how big the melt zone.by MechaBits - General
If you noticed the last picture was a little bit of a joke, then top marks to you. Overall the shape would fit my setup, when the X axis rods are above each other, rather than as they are now. Back on the trail of the Tripple dribbler, I've altered things for V3, though space for the heaters is limited, if the standard cartridge is ever reduced to 3mm diameter then this arrangement might be moby MechaBits - General
Not 10 cents, but cheapish Just need a micro version, cant be long before the spring in your pen example could do the trick.by MechaBits - General
what about the single nozzle stack-able Copper Killerby MechaBits - General
The problem with that approach is, they screwed you, and what your supposed to be nice... same with the people who used my images, they only tried to get me on board, after release of campaign when they where rumbled...he gave me all this bull about how he'd already invested 6k of his own money...I said on what? Not me that's for sure!by MechaBits - General
Or do a whois send the take down notice to the web hosts, see what happens?by MechaBits - General
Cool...can you confirm hole size & spacing they are listed as 5mm holes and cant remember spacing but remember it wasnt 209mm, slight redesign needed for it.by MechaBits - General
Isn't 400 too many? Cant remeber my exact settings at the moment, will interrogate the printer later I asked a question or 2 about this earlier in the thread but no clues yet.by MechaBits - General
Not sure as they are not trying to be you or your trademark. It's a sad old world, you would think someone with some skills in printing would want to design their own objects, just plain lazy to DL another model and release as is, I doubt they used Shapeways for the parts...they would need to sell it for £300 if they had. One of the reasons many of the things I put on grabcad dont have models, iby MechaBits - General
My £10 HiFi Stand with spiked feet will one day be something much better, with about 3 foot of Z to play with. Should I want a 3 Foot high lump of plastic cluttering the house up...I wonder how many kilo's of filament a vase that size would use...hmm I wonder how much a potters wheel is...far more therapeutic & environmentally friendly.by MechaBits - General
So are you using one psu for arduino & bed or are you running two? I have a 33a psu was thinking of getting the MK3 but might run at 12v for plaby MechaBits - General
84 pages of fans on grabcad, one hell of a lot of study material. I got about a quarter of the way through the endless pages of the study, before running for the hills screaming.by MechaBits - General
