2.0 Grinding
2.1 Grinder Operation
The ProtoCycler must be powered on at all times to operate the grinder! The grinder relies on an electromagnet
interlock that engages the grinder drive train only when supplied with power. The electromagnet is calibrated to
disengage the interlock at set torque limit value to prevent damage to the gear train. Lastly, the grinder will only
work if the two interlock switches are engaged while the unit is powered on. One switch is engaged by the grinder
lid, and the other, by the grinder drawer.
2.1.1 Grinder Safety:
Please thoroughly review the safety precautions before proceeding with grinder operation. Failure to do so may
result in serious injury or irreparable damage to your device.
2.1.2 Grinder First Time Setup:
1. Remove the Crank Arm and Allen Key from the packaging.
2. Use the Allen Key to remove the screw and washer from the Grinder Crankshaft.
3. Place the support washer onto the crankshaft.
4. Install the Crank Arm over the hex on the Crankshaft with the handle facing outwards
o Note: the hex size is 5/16”.
5. Replace the screw with the washer under it, and tighten until snug.
2.1.3 Operation:
Note: It is not advised to operate the Grinder while the Extruder is running. Grinder operation may shift or vibrate
the unit which may affect filament quality.
1. Power on your ProtoCycler
2. Remove the Grinder Lid and place the part you wish to grind into the grinder hopper. Place the lid back in
the hopper. The lid and drawer must be correctly installed in order to operate the Grinder.
While the lid only needs to be partially in, the drawer must be fully seated against the back wall.
Particulates may block this, and so it is necessary to make sure the drawer slot is clean of debris before
reinserting the drawer.
3. To grind, first rotate the Grinder Handle counter-clockwise to ensure the interlock is engaged. Then press
down on the Grinder Lid Plunger and rotate the Grinder Handle clockwise. Viewing through the clear area
of the Grinder Lid you will see the Grinder Teeth spin inwards.
4. During operation, if at any time the load on the Grinder Teeth exceeds the maximum, the Grinder Interlock
will disengage. Reverse the grinder all the way until the part is pulled off of the teeth by the clearers, and
