    I removed the mesh entirely on my Super Jolly E and use an artists brush to sweep out chute resulting in zero retention, suitable for home but probably not for volume usage.

    How did you remove it. Cut it out or is there a way to get the mesh out?

    I cut it out with pincers, I thought long and hard about doing it but after experiencing the excessive grind retention it was well worth it.

    In the Robur you can remove the filter by removing the doser cone with a couple of allen keys, and then the mesh is simply a springy laser cut metal sheet held in place by tension. Hold the mesh bits with pliers and carefully lever then flick out the sheet with a knife blade so you can reinstall later if you want.
    But don't do what I did once - not use the pliers! It flicked out, then dropped into the hole in the grinder body. Had to disassemble half the grinder to find it and get it out again! You can't turn a Robur upside down and give it a good shake…
    (maybe a few bits of tape and a sheet of paper over the hole is a good preventative measure)

    On the ECM the grid is attached with two bolts; it's easily accessed on the V Titan through the top of the dosing funnel so I might try removing it and see what happens. I don't mind brushing the chute, this might be the perfect compromise between single dosing and timed grinder... or it might spray half a kilo of static-y grinds errywhere! 😂

    Yeah - removing the screen does introduce static and clumping (I never really had to worry about it before)… I'm still tossing up whether to keep single dosing the robur for ease of use but lots of mess, or just using the Lido!

    I use a small mesh scoop I bought from a kitchen supplier in the bottom of the cone to stop the static and clumping and just flick it with the brush when I clean the chute each dosing, it reduced the mess markedly.

    Great stuff, had mine for 2 years now, and it has been a bit of an issue (2150 grinds so far). Will give this a go myself.

    Are you able to post a pic of the scoop you used? I have terrible static issues with my fiorenzato, as it doesn't have a funnel your fix probably won't help but might give me some ideas for my set up.

    I found this one before - might give it a try. It would still add some back-pressure, but easy to remove for cleaning… rather than screen / wires

    Mazzer Mini E - simple grid mod

    Tried with some plastic but didn't really work ...
    But in a flash of inspiration the handle part of a black bulldog clip, with the two end filed to a flat to grip in under the lip of the funnel edge, gives a Great, easy to remove screen! Will see how it goes the next few days







    And with the springiness of the clip, with the flattened ends it really grips tight ....

    Very inventive DBC, I like it, fingers crossed.

    The scoop sits in bottom of cone.

    Worked a treat this morning. Did remove the static pretty effectively, but I still couldn't clean around it. I doubt I'll use it while single dosing (takes too long to remove them, and I grind into a separate vessel anyway) but I will certainly use them when I do events. Saves having to take the funnel off to re-install the screen.
    I've tried events without the screen, but it has the tendency to avalanche every now and again. 5g … 10g … 15g … 35g!

    Ahhh, I had a mental image that they would swing up or down pivoting on the cone chute sides for quick easy access without removing. Maybe not?

    It does - sort of
    There is not a lot of surface area there to hold onto, so the filed ends grip under the lip of the sheetmetal funnel. Holds beautifully - but tends to simply spring off when rotated. Great if it could though - maybe more modding required!

    Try filing the ends into a cone as if you were sharpening a pencil, elongating the cone so the tips seat well back under the funnel so they sit firmly in place. Having the ends being a cone will let them rotate freely, rather than jumping as they do with the flat ends.

    Ahhhh yes - now we're thinking.
    However, the one disadvantage – this would tend to negate the current 'springs nicely closed flat against the edge' which the current version has - and might rotate back out when pushed by the coffee stream. But two 'cone' rotators, held closed by a … spondonical … of some description could be a winner!

    Think of a watchmaker's screwdriver...

    Looks like a conical end but under magnification, it's a minute flat screwdriver. It is possible that retaining a very small flat edge, or an elliptical end, will allow you to swing the devices away when needed as they could then be held in place by the slightly larger dimension...
