Henry, In Mach3 or EMC I would declare that the spindle was step and direction and use that output to control the extruder stepper. In the G-code the step rate...
sorry, I cut-n-pasted the link wrong, the second link should have been one of these: ( this has sample gcode) http://blog.reprap.org/2009_05_01_archive.html (...
... Mach3 works that way, there are a few options for external controllers if you need higher step rates. ... No, EMC2 can produce software-generated step...
... No, EMC2 can produce software-generated step pulses on the parallel port, or use a variety of step pulse accelerators and/or servo interfaces in PCI slots...
... OK, the confusion here is that I thought the "output to .... whatever" meant MOTION control commands. I think what I said DOES apply in that case. If you...
I added more pictures of the robotic arm that the 3D printer made. What I like is that he designed the parts , printed them and he now had a working 6 axis...
... I don't know about this particular setup, but gravity is very weak at these small scales. Figure the weight of a couple mm long bit of .015" diameter...
Here's an article written by someone on the Mach3 forums about his efforts to get reprap working on a cnc mill run by mach3 machine: "With what I know now it...
Interesting UW is about 11 miles away from me and Spectrum glass is about 2.5 miles away. If anyone is interested in the UW process that they have made open...
Has anybody seen any more on this process? Specifically I am interested in the ability to produce actual transparent parts and the ability to produce...
Brian, I have! I don't think it will produce clear transparent objects. They might be able to produce translucent parts. Temperable don't know. Solid maybe,...
I would expect the parts to be translucent, like 'cracked glass' rather than transparent like a window. When heated and even sightly melt they will deform. ...
I did a follow up on this article because the UW and Spectrum glass are local. 1. I emailed Mark Ganter who runs the ME rapid protyping department and asked...
Dear Group, I take some exception to Dan's post. Fact, he sent email @ 12:09 pm. As near as I can tell, Dan then posted here directly next. Wow. Thanks for...
Dan, There's a whole bunch of applications where ABS is the wrong material. For example, the American Bureau of Ship (ABS) has not approved acrylonitrile...
... Cool, keep it up this way I don't need to spend too much money on research.Have you try PVP in the cartridge? how about something that has plastic like...
As much as 3D printing in any medium, glass, metal, plastics, glue, whatever... no one material is the 'best' for everything, just as no one manufacturing ...
... Agreed, but none of your examples proves that. Power-based printing is any better than FDM for mould making. ... A FDM printed ABS mould of a propeller is...
... Yup there is Reprap and fab@home( both getting better).there is also others 3d printer projects going on around the world but since it's not made at a U.S...
I think your work on the P3P (personal 3D printer) is flat out amazing! I say it now and will say it again. I gave up having students work on P3P because you...
What is the different between STRATASYS, DIMENSION and OBJET printers? As i know the original idea is very old and now patent free (like RepRap). But on the...

... Are you shure about the expired patent? even the maltodextrin mix I'm using have being patented as 3d printer build material having the same ingredients...
what details do you need that can't be extrapolated from the URL? It's an additive FDM, exactly like the reprap, but the feed-stock material is a rod of...
... Yes, but only the original ideas. Newer machine designs and newer materials, thats a different story. ... Thats what i mean. To use a maltrodextrin mix for...
You might get their patent numbers then look them up online. All patents since the 1980's and many before are online at the USPTO. Personally I like to use...
Just because someone else has 'done it' doesn't mean that is all there is. There were lots of 'improvements' between Orville and Wilbur's days and taking a 737...
