Ditting 804 Grinder - Single Dose Conversion Kit

The single dose conversion kit for the Ditting 804 grinder.

The main objective was not to make any non-reversible changes to the grinder itself.

Very effective conversion kit for this grinder, while keeping the industrial look of the grinder. The retention is now pretty much zero, the only retention point is the shoot from the grinding chamber. I've angled it down as much as possible, so there is less chance of coffee staying there. 

Instructions:

There are 2 options. Angled one and vertical. Make sure you print the correct cup holder. 

Non-angled works well, but angled is better and looks badass. Due to the angle, it stays in place but you CAN tip it over. To avoid it I've cheated a bit (sorry kids) and attached an old IKEA lamp clamp to the base and attached it to the cable holder by using a velcro wire holder. Now it's solid. Check the picture. Don't judge my wires it was like that when I bought it, I swear. I do something about it during my lifetime.

IMPORTANT STEPS FOR ANY MODIFICATION:

To avoid getting the nickname “stubby” and getting a good old 220V zombie dance routine:

• Unplug the grinder! Switch on and off to clear the capacitors. 
• Don't put your fingers under the grinder or in any other dodgy places. ESPECIALLY A HUGE CAPACITOR at the bottom. This grinder is heavy, so between you and the grinder, you are the fragile one. 
• It's easier to buy a new grinder than 3d printing a good finger.

Replacing shoot and attaching cup holder:

1. Remove the shaker plate. Real easy to do: just unscrew the from the plate and remove that driving rod from the motor shaft.
2. While you are there unscrew the bolts that hold the rubber coffee shoot and change it to “ditting shoot v2”. You'll see mounting spots on it. make sure to align nut heads with the circles.
3. Optional, but I recommend it. Attach magnets to the “ditting angled cup holder v2”, so it will hold your cup. MAKE SURE THE MAGNETS POLARITY IS CORRECT. It should attract the cup.
4. Attach the “ditting angled cup holder v2” or “ditting cup holder (non-angled)” to the front plate. Make sure it goes under the metal “nose” of the grinder. 
5. put the front plate back on the grinder. MAKE SURE not to break the coffee shoot as the clearance is minimal 

Preparing hopper replacement:

1. Don't be a hero and don't do it when it's installed on the grinder, because if something is false between the grinding plates, you'll need to disassemble them. 
2. Print “ditting top v3”, “top plug”, “ditting pusher v2”
3. Insert magnets with glue. I've used 3x6 mm magnets. MAKE SURE THE POLARITY IS CORRECT, so the "anti-popcorning" plug would be attracted to the base.
4. Cover the “ditting top v3” with magnets in place with the cover “top-plug” so the magnets would be hidden from sight.

Replacing hopper:

1. Remove the original hopper and unscrew the metal plate that attaches the hopper to the grinder. You'll need to drop a few metal plates in the back and rotate the hopper “anti-clockwise”.
2. Attach the hopper metal plate to the “ditting top v3”
3. Optional step. You can put some car sound insulators around coffee paths and walls to reduce noise. 
4. Attach new hopper. Tight fit, but you'll make it. Never doubt yourself =)

Adding stand:

Due to the angle, it stays in place but you CAN tip it over. To avoid it I've cheated a bit (sorry kids) and attached an old IKEA lamp clamp to the base and attached it to the cable holder by using a velcro wire holder (see pictures). Now it's solid. Check the picture. Don't judge my wires it was like that when I bought it, I swear. I do something about it during my lifetime.

1. Print the base with 3d honeycomb infill 50-80%. This is not the part to think about the amount of filament used, because this will hold the mass of all your grinder in place. If it falls, you might flatten your neighbor 3 stories below you.
2. (Optional). Put lots of felt or rubber stickers on the base. Your second half will be thankful for not destroying your kitchen.
3. Put the grinder on top of the base. Probably a good idea to ask your friend to help you out. 
4. Please don't put your fingers between the grinder and the table or base. Otherwise, you will not be able to use the machine with 9 fingers.
5. IMPORTANT! Align the rubber feet of the grinder with indents for them in the base. They shouldn't stick out in any way! If the bulge or deform, use something flat like a non-sharp part of your best half favorite knife to nudge it in place.

Accessories:

1. “ditting pusher v2”. Recommend making it stiff with high infill. Sometimes I use it as below. 
2. “bb-base” is a magnet base for the cup. You can use it to attach your favorite non-magnetic cup to the cup holder
3. “ditting cup v2” is a cup for ground coffee that matches the ‘nose" angles to avoid a mess. Good idea to print with PETG cause it's food safe.

ENJOY YOUR SICK SET-UP!

Advise:

• Don't be a hero and use RDT (spray water on coffee beans before grinding) it will illuminate static.
• Because of the design and aerodynamics of the leaves that push the coffee out of the grinding chamber, they will accumulate some fine particles, so you might have some retention in the first 10-20 grinds. Don't worry it's ok and the retention will go to zero. 
• Use “ditting pusher v2” as bellows if you feel that there are 0.2 grams left in the grinder. They are probably stuck on the edge of “ditting shoot v2” and you will clear it.
