Re: Free...ish - 9 years ago

Thanks for the offer. The nice thing about owning a 3d printer is the instant gratification of making a design and seeing what you did or did wrong. Changing the design and reprinting. Wash rinse repeat... The wait time for mail is just too much for me... Not hyper just no patience. Thanks though.

I have a volunteer to help me with the Printrbot so I'll keep it a while longer! jmrobert48 the Ordbot is yours if you want it. I'll pm you.

Free...ish - 9 years ago

Free...ish means you come get it, it's yours. Be nice if it was for a school(retired teacher) but not necessary. I can no longer physically use my printers. MD as taken all my muscle so can't even bend over to take things off the heated bed. I have an Printrbot Original (the one that started it all on Kickstarter) and an Ord bot. Lots of 1.75mm filament for the Ordbot. One roll of purple 3.0mm

Re: Wooden Eiffel - TriLap joints - 13 years ago

Good choice, I think. I also started one but am still building a rustyspoon huxley. May finish it at a later date. From Desktop The beams are 12" long pieces of ready made trim purchased at Lowes. They are actually 11/16x11/16x12" each. And my holes didn't line up very well either. ~0.5 mm off on several using my cheap Harbor Freight drillpress. Even though the pieces are small the frame is re

Re: Standard Interface for Extruders - 13 years ago

How about something along the lines of a diy zif/edge connector? Basically, two pcb's, one inverted over the other and mechanically snapped together with either a spring contraption or mechanically that would be operated automatically when slotted together. I've never owned a zif connector so I have no idea how they actually work.

Re: Arcol hot end variable extrusion width during print - 13 years ago

jcabrer, You say in your instructions on thingiverse: "1 - 1/4" Brass Auto Hose Female Coupling (these are a little different from air hose couplings) with 1/2" ID on the large end." How are they different? What is an auto hose coupling? Basically, what does it connect? The brass air hose fittings are available lots of places. Can they be used? Guess I could answer my own question by just tryi

Re: Big Printer - 13 years ago

I found some 5 mm plywood at Lowe's. It's used for under layer for flooring. I've cut it into lots of smaller pieces and have yet to find any voids. Very flat and nice looking. Seems quite strong for it's thickness. Comes from China. Doesn't everything?

Teacup on a Repstrap - 13 years ago

Hi, all. I've got all my repstrap's xy and z axii moving with the arduino's stepper test code. Now I'd like to try Teacup. Don't have the extruder or any end stops hooked up. Have three arduino's with 328P's and three 168's chips too(took them out). Fun Toys! Copied the .dist files to the same named file without the .dist and hooked up all the step and dir pins to what I think are the same p

Re: Half a mendel with explicit over-reach? - 13 years ago

by turning it to the side you have reinvented the typical cnc. I also had trouble getting enough z height for the repstrap I've been designing for the past year and 5 or 6 iterations. Start making a mendel and end up with something else: picasaweb.google.com] no-repeat left;">Drop Box

Can you upload your makefile here? I'm just about to the point that I need to work on it too. Unfortunately, I'm lazier than you said you were. I'd rather start from one I think will work for me!

Four bearings and GEARS! Sorry for shouting Which gears. The couple I bought were like $7 each. X4 ouch. More pictures please. Took a while to get back to you. Been getting the Christmas lights up and running. Look good. Arvin

Re: Building a Mendel: A Noob's Tale - 14 years ago

Pretty enough for my desk. Have more pictures? I'd like to see how you did the z axis. The xy rollers on soft wood? Hmmmm....might have to put a metal plate on top to keep it from making indentations. I'm trying to use some electical conduit for the x and y axis that seems to be working. But really interested in what you're doing on the z. Arvin

Re: New Mendel RepRap at the University of Oklahoma - 14 years ago

Congratulations! I'll toast you with a non-University approved adult beverage! Congratulations....I've played with these things for about 5 years and still don't have a working repstrap. Close at this time, but not yet printing. Arvin

Re: Helium Frog Delta Robot - 14 years ago

Actually, if I were to make it out of steel I'd use some 1" wide strips and let the corner threaded bolts clamp them tight. Each corner would need at least one more connection to make them solid. MDF is easier for me since cutting steel is a sweaty job with a hacksaw and I have a table saw, skilsaw, etc. I work hard to make a job easier...does that mean I'm lazy? Maybe...

Re: soft grip filament drive for extruders? - 14 years ago

The first pinch wheel that Zach of Maker Bot when he was still at the reprap store had a bead of clear silicone caulk around the edge of the pinch wheel. It worked. Don't know why it was dropped but I'm guessing that the toothed gear held the filament better. Wish you would follow this up though. If you can find a small hard rubber wheel that has a bearing or bushing I think it would work. Arv

Re: 3D Scanning from photos 0.8 beta release notification - 14 years ago

Be hard to use David on say a model of T-Rex or say a model of a Mastodon basically anything bigger than a sheet of paper. Great work Reece. I'll be happy to use it if I ever achieve printing. I'm to cheap to buy the parts and in the past 5 years I spent far more making various DIY contraptions that just didn't quite work out.

Re: Reprap green house / heated chamber - 14 years ago

$16 compared to the price of just the bolts is minor but 1/2"x10' conduit is in the $2< price <$3 range and is stronger than aluminum in almost any diameter though strength to hold basically plastic rap is immaterial. The price difference will buy your lunch at McDonalds!

Re: Nozzles with a slot for a thermistor or a groove for wrapping nichrome? - 14 years ago

@Viktor...Have you got a part number for either of those resistors? What would you need to use one. Just an ADC pin? That is very intriguing.
