Controls & LED indicator
The electric slow feeders (Metal, Ultra, Pro V2) have a single power button with a built-in LED, plus a speed dial.
Power button
Section titled “Power button”Speed dial (0–9)
Section titled “Speed dial (0–9)”During operation the feeder disc turns counter-clockwise to dispense beans, and the built-in anti-stall automatically works through bean jams.
Anti-stall is most effective from speed setting 5 and up. At settings 2–3 the motor turns too slowly for the anti-stall routine to reliably kick in, so beans can wedge and stop the disc. If you see frequent stalls at a low dial setting, turn the dial to 5 or higher - that’s the fix, not a hardware fault. (Stalling on every setting is usually a low battery - see Charging & battery.)

Grind-by-weight mode has its own patterns: see the grind by weight guide.
A fast blink means the motor hit something it couldn’t clear. Empty the beans, clean the feeder disc, then power-cycle.
