RepLab: The Open Source, Replicable FabLab
Since the RepLab concept owes so much to the RepRap project, it seems natural to have a discussion about it here. Marcin Jakubowski of Factor e Farm recently raised the topic of open-source FabLabs as...

It sounds very interesting; I'm quite impressed with what you group has gotten up to, especially with the plasma cutter, LifeTrac, and Liberator. I'm very interested in bootstrapping RepRap into other...

Thats interesting and its close to the direction I want to head although I'm thinking of something slightly different. Because of its increased size I would look at designs that can be folded when not...

I'd drop the foldability requirement, straight off, for the 1.0 version. Aside from a 'Murphy-bed' version cnc table, maybe. But every time we fold, we lose some squareness. You want cheap, stiff, and...

Portability and ease of transport are a serious consideration. You can't cheaply ship or source parts for a machine that weighs more than you do and thats why I want to do a design that moves away...

Different processes are optimized for different materials. A cabinetmaker, a machinist, a bronze sculptor, and a robotics geek have different tooling and workflows. Also, we need to distinguish...

I'll have to come back and edit this later but I think this is a good discussion, because there is a balance between being able to do everything and being over specialized. Its also important to...

Lawrence, I'd enjoy seeing the final form. That will not stop me from chattering/taking potshots now. :) Sometimes a cabinetmaker will use a CNC router, sometimes (s)he'll use a tablesaw, which is a...

I agree that there will be many different paths to take. One goal I have is I want desperately to work with metals in a safe fashion. Most methods of direct or indirect heating create fumes. My...

I'm afraid I'm about to kill the conversation, so to get back on topic. It sounds like you really want to add a router drill to the RepRap, since it would satisfy the majority of your requirements. I...

Er, wow! What great discussions. Lawrence, I know the RepLab list would love to have your observations and knowledge about RepTab. There doesn't seem to be a ton of information on Marcin's blog,...

Hey guys, I have a complete machine made entirely from store-bought parts and 1" gridbeam. Another of the Michigan RepRap group members was even able to figure out how to make respectable NEMA-23...

Looking at the google groups pictures, I like the use of hardware parts! I think it would be a great idea to put up plans for a repstrap/mill that takes up less room than the currently advertised...

I see your point on using perforated angle iron, and we'll need to do up a variant using it. Contraptor or mntc.ru have done this, recently and ages ago, respectively. I have no idea if they'd like to...

I don't mind at all publishing Reprap-related Contraptor projects on Reprap wiki - the more people learn about Contraptor the better. More so because it's making use of Reprap developments: stepper...

Should I just create a Contraptor page on the wiki then? Please do. You may want to use the [[Example]] page as a template. I document the same approach (centerpunch all, drill only what you need, as...
