Re: Sextupteron
I obviously found sources for all that I listed but I just don't have a source for the 7 stepper solution that I need to make this a reality. At least I haven't found a complete solution under $150.

I have sourced some of the aluminum tube that I suggested on the other design. That stuff is *heavy*. It's also a bit exciting to cut. The PVC is probably a better way to go for a generic design.

I played with shrinking the printer in the way I mentioned above. It was quickly evident that having the dropped bed would not work with the smaller footprint. The design changes quickly started...

It's a pity that Decapede hasn't made it to production. I'd like to help, but I don't have Altium. I've no idea what sort of price they had in mind...10 steppers surely enough for everyone?

@uncle_bob: Yeah, it seems like PVC doesn't get much love but it is so cheap, very easy to source, and very easy to work with. I figure that people can substitute anything they want for the columns...

Hi Hercek I've done a couple of prints of the same object (tree frog) with and without the fan. It's definitely better with. The previous effector had three 25mm fans just angled towards the nozzle....

Oh, I can find legitimate uses for more than 10 steppers. Let's see...a Sextupteron with full color printing (I assume you would want at least 4 colors to get a decent spectrum.) and a gripper for...

JohnL, I'm working on the hot-end now, what the heck is the purpose of the Hot End Plate?

Hmm, there's a challenge :) The cost per CPU pin goes down as the package size increases, but the soldering becomes increasing difficult. Splitting the task between multiple CPUs needs a high-speed...

JohnSL, I figured it out I think. Its a three part sandwich.

@uncle_bob: My simplest idea to eliminate backlash. A set screw pushes apart two halves of a partially slit nut. A ball nose spring plunger set screw applies a constant anti backlash force, (2 to 5...

Ok, The outer wall of the barrel of the flange nut to the high point in the thread is ~ 0.160". That's going by what I can measure on one sample with a dial caliper. (you might have another 0.020) A...

I think that moving the supports in takes care of most of the footprint issues. If you pack it in to tight, getting the print out of the machine will be a hassle. A max height / max diameter cylinder...

@uncle_bob: I bought 24" screws. This gets me around 250mm of print height.
