Number of Shells for Solid Parts

by andrewchoy

Hi everyone, I was wondering if anyone knows if more shells in a print with 100% infill does anything to increase strength. For instance, if I printed a completely solid part with 2 shells vs the same solid part with 4 shells.

I am using ABS for this, and I'm looking to make a part that can withstand as much pressure and stress as the material can handle. Or maybe if a 0.6mm nozzle instead of a 0.4mm nozzle could be used for added strength in a completely solid part.

tevo tornado problem

by abuzaidalam

hi, i have been trying to setup an e3dlite6 for my tevo tornado, i have read that you can solder the heater and thermistor wires so i joined the new thermistor and heater cartridge to the old wires which were all wired in, and now when i test heat the hotend to only 60c the hotend heats up and then the screen of the printer goes blank and turns of and the hotend begins to cool down. the printer tries to turn on again, but then the screen turns off. i checked the wires for the screen and everything else, but they all seem fine.
i am wondering if there is some fuse blown or something like that. i checked to make sure that the hotend requires 24v which is what the tevo tornado voltage for the hotend is.
does anyone have any suggestions for what might be wrong?
thanks in advance for any help

clock charge cellphone

by jamesmatheson

So i learned a clock can charge a cellphone https://www.behance.net/gallery/1902587/Cyclus-Step but the fault is that it needs a gearing that makes the most rpm change with the least torque loss. I was shown a bunch of harmonic gears that have a 100:1 and one with a 1379:1 but he said it cant be used as a crank for a dynamo, if anyone has any recommendation there is a huge cash prize, please share your thoughts

FULL BODY 3D SCANNING SETUP

by Coolcrawler_

Hi, I want to make a full body 3D scanning setup like this one: https://www.thingiverse.com/thing:1185566. I like this one but it seems to complicated for something that should only need an Arduino Uno or NANO. I already have a motorized lazy susan for a person to go on.

I have looked on Youtube for inspiration and have found motorized camera sliders; but I want limit switches on each side (for peace of mind) and I don't need anything fancy like a pinchwheel encoder or LCD screen, just a single button to make it go up slowly, hit the top limit switch, go back down and hit the lower limit switch. I want the whole thing to be powered by a NEMA 17 stepper motor. I just need someone to code and tell me all of the parts needed. It is basically one axis of a 3D printer, I guess.

So if anyone could help, that would be much appreciated.

Thank you
