QuoteNumberSixOne possible solutions might be to be able to control the fan direction. They can cool the heat-sinks when air flows in either direction (we can debate which direction cools better), so when you are first printing you suck air up, then when you want to cool the work you blow air down! Just a wacky suggestion!I like it but how would we make the fans spin backwards? Simply reversingby Dark Alchemist - General

So, the fans are pulling air through the Heatsinks instead of pushing? I know in the PC world it has been proven that pulling through instead of pushing through offers less cooling. Any reason you went that way?by Dark Alchemist - General

I must reinvestigate a Smoothstepper but I have not heard of Kflop before. How would I get my stl over to the controller? I hope I could use my Windows 7 based pc (I refuse Windows 8 and hope Windows 9 comes back to sanity) to send the files over and I saw this one guy who Bluetoothed his pc to his CNC to make the motors work as he demonstrated it. btw, this is what confuses me QuoteThe videoby Dark Alchemist - General

One I saw was a long tube then the head which should?!? work as a guide for the filament? The one you are talking about just looks freaky and the filament would be too cool by the time, if it even could, exit the end. Still, these aren't made for heat, and we do have a lot of heat on these, so I must wonder how well will they stand up?by Dark Alchemist - General

I believe so because anything that controls the servos in a 64 bit world will be awesome. You know I have some program that I tried that generated g-code and it worked in Windows 7 64 bit so really the last hold up is Mach 3.by Dark Alchemist - General
QuoteDark AlchemistYES, YES, I was thinking about airbrush nozzle as they have them long and slender and tiny orifices but I wondered if they could withstand the heat since an airbrush doesn't get hot.

Aye, but that doesn't do me any good if I have to go out and purchase NEMA 17's to get it done.

So, where does one go to buy these antiquated operating systems or does one have to resort to piracy to get them (Microsoft will not allow you to sell your old version of the program once it has been used and it is considered piracy unless the package is pristine and the key as well)?
