Motor visualizer

Extruder movements on both MK2/S and MK3 can be quite difficult to see.

Even though these rotation indicators are mostly just for a cool look, they can be surprisingly handy when you’re dealing with a jammed extruder, overtightened idler or playing with retraction settings. You’ll be able to tell what’s the extruder doing at all times.
