    Winter reeking havoc on my grind?? [Macap M2M]

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    In the last couple of weeks Iíve been struggling with getting my grind dialled in.

    Usually with a new bag, I might sink a few shots getting it dialled in, but after that I pretty much make minimal adjustments and can compensate by adjusting dose slightly. Iíve got a a MACAP M2M stepped grinder.

    However, in the last couple of weeks, I just canít get it right.

    Iíll dial in a new bag of beans and everything is good - come back later in the afternoon or maybe next morning and I need to go three full clicks finer to get it pouring right. Come back again later on and the same setting is choking the machine and I have to go three clicks the other way to coarsen the grind. Rinse and repeat.

    Apart from pulling the grinder apart and checking that everything is sitting right, is it possible that with winter setting in here in Melb, and thus the heater running here and there, this is causing changes in the ambient conditions that are causing my grind to be unstable?

    Iíve never had this issue of having to swing back and forth several clicks each time I pull a shot. Usually once dialled in, the pour is almost spot on morning to morning. If I feel like a second cup I might adjust dose up or down 0.5g to get it even better, but thatís about it.

    G'day dbun

    It sounds like the chamber is full and it needs a clean out. A full chamber futzes up either / both the bean feeding and the particle spread depending upon the specific grinder.

    Hope it is that simple

    I was going to suggest the same. Pull it apart and see how much grinds is caught up in grinder.

    I like a cable tie as a probe, plastic, but bendy and semi moldable

    Thanks both for the suggestion - I‘ll give the grinder a good clean out.
    To be fair, the grinder has not had a decent clean out in the couple of years I’ve owned it. Machine gets all the attention!!

    Grinders do need regular maintenance to perform at their best, I pull mine apart, clean grind chamber, chute etc and lube threads monthly.

    Two years without a good clean is pretty excessive, would expect the internals to be caked with fine coffee gunk.

    I suspect a clean will make quite a difference.

    Just to report back - cleaned the grinder out and it seems to be performing better, but need to try it a bit more to see if it's fully resolved.

    Might try and sweep out the chute more regularly and pull it apart for a good clean more often too - are there any tools for sweeping out the chute without pulling apart the grinder?

    Cleaning the M2M is dead simple dbun, suggest doing it regularly (minimum monthly) to keep the grinder performing at its optimum.
