Anet A6 fan issues

I just noticed, and I KNOW it was not a problem before. But recently the fan that blows over the nozzle has been acting funny. I have it set to start blowing after 3 layers, and then turn on at 100%. I decided to watch so I can give more information…

Supports for dense Voronoi pieces

I have printed 1 voronoi piece before. I was able to get the supports that were inside the structure out with tweezers because the holes were big enough. This one (pic below) I do not think I can do that with. I looked at the proposed support…

Nozzle reducing flow as it comes close to finish layer

I've have observed that when the printer is finishing a layer, the flow of plastic through the nozzle starts fading out as it comes closer to the point of layer change. As an example, let's say that I'm printing the first layer of a cube. The nozzle…

24 V heated bed from -12 V and +12 V ATX power supply?

As long as there's a MOSFET in between, can I supply 24 V bed/extruder heat from an ATX power supply using -12 V and +12 V and ignoring the common rail? I assume so, I can't think of a reason why not, but want to check.

I'm attempting to model and print a globe. The semi-circular arm that holds the globe has an outer diameter of 98mm and inner diameter of 92mm, so the arm is fairly thin. The arm has a small hole on either end that fits around a protrusion at each…
