JHCCoffee Matey you don’t have to over-think these things 🤦‍♂️😂

If the hole on the disk is too small for you then remove it. The Niche isn’t a quick grinder and it wasn’t designed to be.

      One of the things I like about this espresso hobby is it’s challenges and the need to analyze / think about things. I am an analyst by profession, so this aspect resonates with me.

      I am sure that you were well meaning, but please do be more respectful in your choice of words and emoticons when responding to posts. Everyone has their own perspectives and preferences. This forum is quite respectful of this. Everyone seems to be on this forum to be helpful (as distinct from critical), which is why I like this “worlds most friendly” forum, relative to others. Enough said.

      I am pursuing an in between solution by 3D printing a disk with a larger diameter hole. If that does the over thought trick for me, I will let this forum know.

        only thing id say with the bigger hole is watch for beans getting stuck under the disc, only had it twice with some giant beans

        I’d try without the disk first. If that’s not significantly quicker then a disc with a bigger hole won’t either.

        JHCCoffee Question: What filament, resin, etc could/should I specify? Or do I just upload the file and set the machine to work?

        Never used a 3d print service before but made mine out of PETG filament, only other thing you may need to specify is 100% infill, I’m afraid my 3d printer has not been set up for a while otherwise I could have bunged you one in the post.

        Like others have said I would definetly give it a go without the disc and see how you get on.

        I have posted a couple of dimensions of the NFC disc i was sent below if anyone fancies comparing it to theirs just to see if there has been any changes since the original ones where sent out

            How deep the cut out is

            MediumRoastSteam What’s the second measurement?

            Second measurement is from the back of the cut out to what I judge to be the centre of the bolt hole 7.68mm,that is the only way I could see to judging the depth of the cut out

              And diameter of disc is 39.9mm

              Thank-you Ken, for taking the time and trouble to provide these files, pics and measurements for all of u! Very kind of you.

              This Forum continues live up to the friendliness and helpfulness bar set by DaveC.

                  MediumRoastSteam And it’s exactly 3mm thick

                  Mine is 3.1mm thick, might not be much but the extra thicknes and 0.3mm smaller hole may make all the difference, I remember once I used a different 3d printed design for the disc and found that to be a lot slower and inconsistant, I wonder if we have any other genuine variants out there

                    JHCCoffee Thank-you Ken, for taking the time and trouble to provide these files, pics and measurements for all of u! Very kind of you.

                    I just tried a grind with no disk. I’m not enamored with the extent of pop-corning. I also noticed some bean fragments that are staying in the hopper (that were pop-corned out of the burrs). So, I just sent out your 3D files to a 3D printing service. I am awaiting a quote, but as the cost is likely to be low, I will give them the go ahead. No harm in trying this out. Stay tuned.

                        Going back to the original post, is there a reason you’re only dosing 16g in an 18g basket? And is this what you did with the previous grinder?

                        Typically (but not exclusively true) under-dosing or over-dosing by that much can cause unusual extractions… caused by either too much water filling the headroom above the puck, or the screen fracturing it.

                          Free Modified NZ Disks (if you want them)

                          Just made an arrangement to have the modified NZ disk (that @ken0062 is using) to be 3D printed. Their minimum order is $50 Cdn, which means that they will be printing 8 disks. I need 2 for my city NZ (1 + a spare) and 2 for the NZ that I will be buying for my cottage setup (to replace my Baratza Sette 270).

                          So, as a thank-you to those on this Forum who have been most helpful to me (especially MediumRoastSteam, @Rob1 , @CoyoteOldMan, @Cuprajake, @DavecUK, @LMSC, @tompoland and anyone else that I apologetically missed), and of course @ken0062 (who came up with the idea), I would be pleased to mail 4 of these across the pond, to whoever would receive the envelope and then take it on themselves to distribute to other interested Forum members. If you are interested.

                          Let me know, by PMing me at julian dot colman1 at g mail dot com.

                              Ernie1 Going back to the original post, is there a reason you’re only dosing 16g in an 18g basket? And is this what you did with the previous grinder?

                              I’ve been dosing 16.5g of decaf in the 18.0 gram IMS basket. This was based upon an earlier suggestion by one of the Forum members to allow 1 to 1.5 g for headroom, especially for decaf beans that are roasted to a medium-dark roast (say City Roast). Any feedback is welcome, as I am still not getting the mouth feel and strength, but also taste and complexity - I want both - that I desire. Any suggestions are welcome.

                                  JHCCoffee just a thought, before forking out that much why don’t you just dress your existing NFC with a file to make the hole slightly larger, still be cheaper to buy a new one if does not work out

                                      ken0062 just a thought, before forking out that much why don’t you just dress your existing NFC with a file to make the hole slightly larger, still be cheaper to buy a new one if does not work out

                                      Thanks for the thought. However I don’t think I’d be able to file or drill it to a sufficiently precise or even or smooth diameter. And I’d never know whether it was the new disk design that caused a less than expected result, or just my bad filling/drilling.

                                      I suspect that I will like the happy medium that a larger notch will offer, so I guess I’ll just take the risk.

                                      And if I don’t like it, I’ll pass these disks on to other Forum members (or others) to try out, as I suspect that other folks may wish to test it out.

                                      I work by the principle of: “what goes around comes around”. Happy to gift small items to Forum members, as the advice I’ve been getting has been most valuable.
