Hotbed LED during operation
I finished assembling my kit just recently and have been trying test prints. I noticed that the red hotbed power LED (between the hotbead and the power wires attached to it) flickers a lot while printing, and the flicker isn't entirely consistent. I also noticed the power supply makes some rapid clicking sounds for a little bit while the printer is booting up and preparing for a print. Is this normal operation? I'm a little touchy since I did the assembly myself, though as an electrical engineer and a tinkerer all the connections felt good to me during assembly.

Re: Hotbed LED during operation
Totally normal behaviour. LED flickers as the heating is being regulated. Many people also report the PSU clicking while the bed is heating.
