    Super Jolly Stall

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hey all,

    I have experienced my Super Jolly stalling on occasion. My process each day:

    - Load about 150g of beans into my custom made small hopper (upside down, cut and cleaned old plastic honey jar)
    - Grind what I need to 2 coffees
    - Pick up the grinder, turn upside down to tip the unused coffee beans back into the bag. Usually ends up leaving roughly 8-10 beans next to the burrs that don't make it out.

    Then the next day when I re-load 150g into my little hopper, once every 3-4 days the grinder will stall when I turn it on. I need to then do roughly a 1/8th collar turn (equivalent to about 10 'notches') to get it to grind and then adjust back while grinding to my previous grind point.

    Could it be somewhat expected that it would stall using this process? As in the inverting to clear the hopper moves the beans / grinds in the chute and then when reloading the next day it compresses them and makes it stall? Or could my SJ be getting a bit tired?

    BTW it's a 2006 build

    Cheers

    Hi Bames
    You must have arms like Hercules!
    Seems like a heap of effort - and I do wonder if the inverting might be jagging up your SJ somehow.
    Perhaps you could leave the beans in your hopper (this is what I do) cut a disc the size of the inside diameter of your honey jar to sit on top of the beans in the hopper, put you tamp on to of that to keep it sealed as well as possible, and see what happens over a few days? If it still happen, it could be burrs?

    Just my second crack
    Matt

    Are you making grinder adjustments while the motor is turned off? This is a common cause of jams

    Have you ever cleaned your grinder?

    Thanks for the replies

    Flynn - no not making adjustments while the grinder is off, and yes I do remove the burr carrier and clean pretty regularly (once a month).

    Maybe i'll just try to seal as well as possible as Matt says and see how I go.

    Have you tried loading just enough beans for the two coffees?
    Then there'd be none left to jam the burrs.

    My thought exactly, cheap set of scales, problem solved.

    I'd be considering a greater issue at hand if an commercial quality SJ jams with more than 20g coffee in the hopper. This could win the battle - but might not win the war?

    It's possible that the units Start/Run Capacitor is shot.

    Might be worthwhile taking to a competent tech. and have it checked out...

    Seems to only happen when I invert the grinder to empty excess beans out.
    If I remove as many beans as I can with a spoon, grind them all out so the chute is empty, leave the hopper half full etc it's fine. Had the big hopper on there the other day with a kilo doing coffees at a mates party - it was fine.

    Must be that inverting does something weird.

    Maybe I'll stop doing that

    Sounds like the sensible thing. Inverting it might throw the motor out of whack.

    tip the grinder forward and grind. I do it when my grinder stalls sometimes and it seems to get it to start again without adjusting the grind settings.

    I suspect your right Matt, with a 350 watt motor it should take a lot more than a hand full of beans to stall it.

    Its a good grinder, get it repaired before you burn the motor out.

    Given these things weigh about 14kg it must be a major pita turning it upside down and shaking it at the end of day.
