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.
