Oh and how do I get one of those etched copper dinosaur fossil pieces? I would love one to hang on the wall. Joeby Joe.McKibben - Ohio, Dayton RepRap User Group
I have not worked on RepRap at all really but I would like to get into it. I am trying to get people together for a hackerspace in Dayton (www.daytondiode.com). If we ever get it up and running I think it will be a great place to work on reprap at. We are in the planning stages and have 8 members so far. I am currently working on getting Dayton Diode made in to a non profit. And after that and weby Joe.McKibben - Ohio, Dayton RepRap User Group
Yeah I will probably get the boards from RRRF. Joe McKibbenby Joe.McKibben - Ohio, Dayton RepRap User Group
Thats great. I have not started building yet so I don't know how much help I can be right now on the know how side of things. I guess I need to order some of the electronics boards and the components and start on this thing. Joe McKibbenby Joe.McKibben - Ohio, Dayton RepRap User Group
Yeah the Miami Valley Robotics Club doesn't exist anymore. I had got a flyer from Boonshoft museum not to long ago and it talked about a robotics group for all ages. I have not found out anything else about it. I have a robotics group made up on google groups. It is not very active. Joe McKibbenby Joe.McKibben - Ohio, Dayton RepRap User Group
To see some builders that are in your area check out the RepRap map on google. Joe McKibbenby Joe.McKibben - Reprappers
I live in Dayton, OH. Not really close. Joe McKibbenby Joe.McKibben - Reprappers
So, you dont have to worry about overshoot or undershoot of your position when using steppers? The momentum of the axis won't carry the motor past its position? It seems that with either a stepper or a servo(already a closed loop) you would need some sort of closed lood feedback system. Especially if your making a large part. Sorry, I have no experience with steppers. Joe McKibbenby Joe.McKibben - Mechanics
Do you have a extruder. Do you have any drawings of the parts you want made up. I may be able to get some made here depending on the materials. It is even possible for me to get them made on commercial rapid prototyper. Joe McKibbenby Joe.McKibben - Ohio, Dayton RepRap User Group

Hello, Have you saw the extrusion kit from Bits from Bytes website for 30 pounds or euros (whatever it is)? Are you going to mount the dremel to the extrusion head or relpace the extruder with the dremel? Joe McKibbenby Joe.McKibben - Ohio, Dayton RepRap User Group
I see that Zach is already working on something like this. On the "Arduino as simplified comm/controller board" thread. Joe McKibbenby Joe.McKibben - Controllers
I am going to have to say that this seems to be a pretty complex route to travel for some simple feedback for the motors. And probably in the end will not provide the necessary resolution. Here is a device I am thinking of It requires an optical encoder input and basically transform any DC gear motor into a servo motor. The encoder could end up driving up costs but with the switch from stepperby Joe.McKibben - Controllers
It is funny how straight of a line some of the locations make. Joe McKibbenby Joe.McKibben - Reprappers
I see. I was just pondering the technology that would be necesary for the RepRap to accomplish some of these goals. "A RepRap doesn't have to be capable of making copper wire, as long as it is capable of making a machine that makes copper wire." That is an interesting concept, I didn't think of it that way.

The melting point of copper is 1984.32by Joe.McKibben - General
It seems that it will be a while till someone repraps the stepper motor. The housing may be able to be replaced with a plastic material and maybe even the shaft. But the coils most definetly willl not be able to. There is also the bushings or bearings (depending on the motor). I will have to look up the melting point of copper.

Hello, I just joined this forum and I hope to start building a RepStrap here soon. It will probably take a little while for me because of costs and things but sounds fun and hope I to be able to contribute to the community in some way. Joe McKibbenby Joe.McKibben - Reprappers
Hello, Does not look like there are many in Dayton building RepRaps or RepStraps. I have an idea of who requested this local forum thread though. I am not sure if I am going to build one yet but I am researching the subject. Joe McKibbenby Joe.McKibben - Ohio, Dayton RepRap User Group
