  1. Hi folks. I bought this as a project to convert to a domestic single doser. I’ve realised since getting it I’m just never going to get the time. I’ve always got a project on the go and I’ve got to finish a mobile coffee station and build a whole solar array before I can start on this. I need the garage space so I’m sadly letting this go. Pickup near Beaconsfield. Looking for £320. As far as I’m aware, these retail for around £1500 but It’s got the titanium burr upgrade which I believe was at extra cost. You can tell why they’re so expensive when you try to move the thing. With the hopper it’s 30kgs! It is a truly beautiful piece of engineering though. The parts all move so smoothly and solidly. It’s in used condition with obvious signs of wear where the portafilter has scratched the paintwork at the base. Apart from that everything else is in great operational and cosmetic condition. I’m happy for you to arrange a courier. The main unit is 26kgs boxed and the hopper would have to go in a separate box at about a further 4kgs. Personally I’d pick it up though! You’re welcome to come see it in person before buying but if you check out my feedback on about a million transactions, you can rest assured this thing is in good working order. It was pat tested by the bloke I bought it from and the sticker is present. Feel free to ask any questions. Here’s the spiel: The Mazzer Royal holds a regal position as the largest of Mazzer’s grinders, towering over the others with its humongous hopper, massive motor and colossal 83mm burrs. This stepless grinder is built to perform, and would shine bright like a diamond in a high volume setting. Owning the Mazzer Royal The Mazzer Royal is a stepless, doser grinder with manual timed grinding functionality. It’s a big step up from the Super Jolly in terms of performance and capacities, though it operates similarly. Its 900 watt motor spins at a rate of 1050 RPM with a whopping 1 horsepower. The extra large hopper can hold four whole pounds of coffee, and the timer dial operation can grind in up to sixty second increments for continual use. The grounds are deposited into a large doser, which can be adjusted to dispense anywhere from 5.5 to 9 grams into your portafilter with a flick of the dosing lever. The doser can dispense up to twelve pre-portioned amounts before needing to be refilled, which it can do automatically, and those grinds can then be easily tamped with the doser’s built-in tamper. Both the doser and its built-in tamper are designed with high-speed scenarios in mind, where you want to be able to quickly grind and tamp for several drinks in a row. We may never be royals, but this grinder sure is; and it would really shine in a high-volume cafe. The Mazzer Royal’s gigantic 83mm stainless steel burrs are stepless, meaning they can be adjusted to a virtually infinite degree by turning the collar in small amounts. Although the Royal is capable of producing coarse or fine grinds, in a cafe environment it’s simply impractical. It’s best to use different tools for different jobs. Let the Royal grind the espresso, and get another grinder for drip and the like. The burrs are easy to access for cleaning, and calibrating them afterward is simple, too. Infinite Grind Settings The Mazzer Royal is a stepless grinder, meaning you can make adjustments in increments of your choosing, rather than a limited, factory-designated amount. This is ideal for dialing in your grind for better tasting shots on any prosumer machine it’s paired with. The Royal can grind for coarse brew methods, too, though we recommend using a separate grinder for those. Time-Based Grinding The Mazzer Royal is manual, and as such it’s a breeze to use. Turn the dial for up to sixty seconds of continuous grinding into the doser, which then dispenses a pre-portioned amount from 5.5 to 9 grams into your portafilter with the pull of the lever. This functionality is super simple, and easy to master in no time at all.

  2. It’s knocking on 25kgs so it’s mildly portable!
  3. Continuing with the off topic Ascaso grinder retention. I’ve found the problem and it’s so stupid. There’s basically a completely flat platform about 20mm deep before the chute begins. Without cutting the metal, I can’t see any way of modding the grinder. The Ascaso designers should be ashamed of themselves! In their defence, they got the grinding part right though!
  4. This is now going to be my method of making coffee at work. Several months in the making. Just finished it!
  5. Hurrah! Drip tray/scales is now watertight. For anyone interested I increased the infill to 40% and the shells to 4 on the 3D print. I reckon the draft quality print just had plain old holes in it. I also cut a wee silicone mat to fit the top of the Gaggia to stop it getting scratched. The top of the Gaggia is a cr*p cup heater anyhoo. I just use a shot of hot water.
  6. If I get round to modding it, I’ll post it all here.
  7. I think it’s really as simple as the exit chute from the burrs just isn’t steep enough plus there’s a lot of redundant space between the burrs and chute that just asks to acquire grounds. It’s a real shame as of the few grinders I’ve owned, it’s actually a surprisingly good grind given the burr size. Better than a Rocky by far. Not a million miles away from a Zenith!
  8. I bought the Ascaso primarily for its footprint and weight. I reckon if I come across a Eureka Mignon cheap enough I might swap it out.
  9. Good move with the bottle brush. Think I’ve got one lurking in a cupboard somewhere. I’ve finished the bulk of the build so I’ll just be tweaking stuff from here on in. I reckon I’ll dismantle the Ascaso and see if anything can be done to improve the retention. I’ll post any updates here and my 3D designs for print generally are uploaded for free download from Thingyverse.
  10. Wonder if it’d benefit from a lens hood mod so I can puffer out the grinds. Could see that getting even messier though!
  11. I think I’ll try a few coats of black acrylic car spray on the 3D printed drip tray. See if that sorts out the waterproofing. Failing that maybe I need to reprint adjusting the shells and infill.
  12. Ok. I tell a lie. 17.3g. More actually fell out before I swept this out though. Pretty bad retention though right?
  13. Ok. Test #2 Grinder: Actually really impressed with the grind so I think I’ll stick with the noise and retention. Combined scales and drip tray: Boooo! It leaks. Doesn’t seem to be between the joining parts. Water literally seems to be seeping through the printed PLA! Back to the drawing board on that one. Design seems solid though. Gaggia: Totally happy. Works just like my Silvia with the added bonus of a quicker warm up. The Silvia steam wand upgrade is ace. Managed to make something approximating microfoam. Just need to practice more with it. Very different feeling to the current steam wand on the Silvia (which I think has three nozzles?). So considering I was using Lavazza beans to test with, I’d say this set up potentially could make coffee 80-90% as good as. My home set up! Back to work on the drip tray. Image shows first drinkable coffee made with it and some diabolical latte art.
