That's easy enough to fix. Don't know why you put those big flanges on your linear platform for the bolts. You could have, I think, just knocked out those pins and replaced them with bolt holes.by Forrest Higgs - General

Yeah, looking at your ascii stl you can see the tiny dimensions on those vertices. I don't know anything about solidworks to know why that's happening to you. At a guess, it looks like it is scaling your drawings to metres instead of millimeters.by Forrest Higgs - General
Corwin... I downloaded those STLs. When I brought them up in Netfabb they were TINY, fractions of a mm in size. It looked like the scaling was off by maybe 3 magnitudes. I took them into Art of Illusion and the same thing happened. I scaled them up by 3 magnitudes and the rail looks like it is 117 mm {100 mm nominal} x 17 mm x 20 mm. Those are very clean STLs.

I lived in South Africa during apartheid and the sanctions and embargoes of the 1980's and early 1990's. We had a saying. An embargo means a 30% surcharge. We needed American torpedoes, we got them from the Israelis at cost plus 30%. We needed another Mirage III to replace one we lost in Angola?

Dell XPS 730 H20 {water cooled} Intel Core2 Extreme Q6800 @ 3.8GHz overclocked Most of the power over 400 watts is taken up by the graphics cards which skeinforge makes no great use of. Now if I run something like Portal or one of the heavy duty games that use both the graphics cards and the physics card that can run up to 900 watts.

Wow! That's weird. I've run Skeinforge on most of the Mendel parts and never had it run longer than about 5 minutes. Some of the nasty gears and geneva wheels I've done have taken a few minutes longer, but never anything like more than maybe 10 minutes.by Forrest Higgs - General
If you have a decent compiler for your MCU you can access SD cards from there. Mikroelektronika {mikoe.com} sells excellent ones.by Forrest Higgs - General
Rapman is pretty much a flat pack reprap.by Forrest Higgs - General
Skeinforge generates gcode files. So does Netfabb. If you want to stream them from a PC that's your job. Me? I prefer the Rapman SD card arrangement. It keeps my total energy consumption for printing down at 48 watts. I only use the PC to design parts, not print them. My PC draws 450 watts at idle.by Forrest Higgs - General

It is one thing to be printing new objects and talking about those objects. It is quite another to be talking about specific problems related to printing things in general.
