    Hi TristanP Feel free to PM me the special price.

    For those dosing, knocking down and then dosing again, I've wondered about this Sette Drop-Down Portaholder Fork listed on Baratza's website ...

    The Sette Portafilter Drop-Down Accessory is an optional device that allows for hands-free grinding into a Portafilter when using a Sette 30. This accessory is also designed for use on the Sette 270 and 270Wi when grinding larger quantities of coffee (say 20-23+ grams) into portafilters, by virtue of providing greater vertical distance between the discharge chute and the portafilter basket. The Sette grinds at very high speed, this accessory will help eliminate backup into the chute, with the potential to clog the grinder.

      Simonsk8r....Sorry, I don't understand what retention refers to.

        Matthew that looks promising. Might look into building a makeshift one for a test run at least.

        The splatter looks to be an on-going issue and it's quite messy. The problem is caused by the ground coffee heaping higher and higher above the basket so that the final grinds shooting down through the burrs have nowhere to go.

        So they bounce off the high mound and onto...everywhere but the basket.

        I'm disposing of them with a portable vacuum cleaner but am looking an a small cardboard tray to sit at the base and fopefully collect the stray grinds.

          Ah sorry I mean how much ground coffee is retained in the burrs area and chute. I was mainly joking as it's a question often asked, but I am curious. I've heard the Sette has very minimal retention due to it being a mostly straight-down path from the burrs down to the portafilter

            I thought that was an interesting question so I just removed the burr assembly, brushed everything out and ran it through a #10 (coarse) grading sieve to separate out the coffee that hadn't yet made it into the burrs.

            Retained fines came to 2.4 g.

            That's only one data point but visually it looked like the amount that I usually see when I knock out the grinder (when I'm trialling something or changing beans for instance).

              Maybe it would be a good practice with all grinders to throw away the first couple of seconds worth for the first grind of the day? Have never thought of that issue before.

                FWIW I have a small flat wooden stick with straight end (formerly supporting a Magnum, now cut and sanded to coffee-cleaning perfection) with which I scrape out excess grounds from the Rocky as part of the current dose. There will be some left in the burrs; less of a problem in that I have reduced the proportion of old grounds. Pending a new grinder, I let it go rather than throwing a little away each day.

                  Yes, sorry, "retention" came to me this morning...
                  Baratza claims this is one of the good features about the design, because the bean hopper, burrs and portafilter are all in vertical alignment. Gravity does its part, and the ferocity of spinning burrs does its part, pushing the grinds straight down into the portafilter basket or other catcher. (That ferocity though, also causes the splatter.)

                  I haven't weighed the amount left behind, but it is minimal. The pictures show the removed burr assembly and you can see daylight where the grinds pass through.

                  The potential bigger issue is that as the mound of ground beans heaps up above the basket, they bridge the gap between basket top and burrs. Something to work on--except I keep running out of degassed beans with which to experiment.

                  The double decker attachment may not be the answer because there is barely sufficient clearance between the portafilter spouts and grinder base.

                    On my 270w, I ground into a curry paste jar. This is the correct size to invert into a portafilter.
                    The jar would sometimes slip, so I used a strip of tape around the arms and under the jar to support it. This provided a much more consistent dose as the vibrating unsupported portafilter arm would upset the scales.
                    I like the idea of a paddlepop stick to probe out retained grounds! I used a cable tie with a bend in it.

                    The unknown Allen key is used to undo the burr to install the shim/s.
                    The lower burr carrier is no where near as hard to install as described. Perhaps the poster has limited mechanical aptitude, in any way, he is gaining it now!

                      I kept maybe 100g beans in the hopper. Grind my dose.
                      Then invert the whole machine to get the beans back into the hopper, shut the hopper trap. Revert machine, Grind the remaining beans caught in the burrs, clean the 6 little holes shown in the post above, remove hopper to the pantry for next time.
                      I found the 6 holes would retain grinds and clog.

                        Limited mechanical aptitude? Mois? Err...hardly.

                        FYI I've rebuilt car engines, have done my own servicing on my "fleet" of cars for decades, fix broken appliances -mechanical or electrical, am a darned good wood worker, metal worker, boat rebuilder, draughtsman, house extender; disassembled, repaired and cleaned my commercial Grimac coffee machine, taken apart and reassembled my commercial Cunill grinder upteen times, added a PID to my old Silvia ...etc etc

                        In short, the ultimate handyman. (But gee, gosh golly, I'm far too modest and bashful to say so)

                          OK Robusto, we can see you can do the easy stuff, but have you ever tackled anything really challenging like change a 270Wi lower burr carrier!


                          Nice review, Thanks

                            338...haha, a tough one!��
                            The fault, dear Brutus, is not in ourselves but in the assembly done by others....

                            In my new house the power kept going off intermittently. Finally I located the problem to loose wiring at the fuse box.

                            My central heater blower started making a racket...Located the problem to a loose bolt which secures the blower to the fan armature so that it spun off balance.
                            Fascia boards on my house rotted: Original painter used one lousy finish coat and no primer. Wooden window sills rotted: bricklayer hadn't left any clearance between his brick sills and the window so the wood curled up and retained rainwater...

                            Yes, I am forever having to diagnose and undo the sloppy work that people with supposedly better skills than me make my life...interesting.

                              My 270WI arrived earlier this week. Made use of a 15% off eBay coupon to get it for $567.50 delivered.

                              Only put ~300g throught it so far, but first impressions are VERY positive:

                              - Weighted dosing is remarkably precise once (checked against Acaia Lunar)
                              - Getting the grind dialled-in for my machines has been dead simple
                              - All of the grinds are landing in the basket
                              - The auto-correcting ("AI"...derp) dosing is like magic.
                              - It's fast!
                              - Stable and unobtrusive on the bench
                              - VERY high WAF

                              Only downside, really, is that looks/feels a little cheap. But it's *half* what I originally paid for my Macap M4D so I wasn't expecting the build of an Audi for the price of a Kia.

                                Sounds like an advert for EBay.
