Do the TW, THW and THHN or THWN wire insulation types matter in terms of powering RAMPS 1.4 or the MK2a Heat Bed?

I'm still looking at wires for my Prusa i3, to go between the power supply and RAMPS 1.4, and the power supply and the MK2a Heatbed. I also recently found a 400 ft. Wire Storehouse that I bought from Harbor Freight which has wire sizes in it from…

Bad filament with changing diameter causes an uneven flow of plastic out of the nozzle. Besides buying very high quality filament (do we really want to be dependent on professional Filament producers?), what other ideas and methods could be used to…
