  2. Put a single, small drop of thread lock onto the set screw thread. Most people use want to use way too much threadlock. Really, little is enough.

    • Put a single, small drop of thread lock onto the set screw thread.

    • Most people use want to use way too much threadlock. Really, little is enough.

    • Let the threadlock spread the thread lock into the thread. Soak excess with a paper towel if necessary.

    • Tip: Keep the set screw on the hex key for easy manipulation.

  3. One of the set screws may be shorter than the other one.

    • One of the set screws may be shorter than the other one.

    • That's nice, but not necessary. If your two set screws are identical, don't worry about it.

  4. Re-insert both set screws into the pulley.

    • Re-insert both set screws into the pulley.

  6. Slide the Y pulley onto the Y motor shaft.

    • Slide the Y pulley onto the Y motor shaft.

    • The set screws in the pulley should be on the side close to the motor.

    Edit

  7. Make the top of the motor shaft flush with the top of the pulley. Tighten the longer set screw against the FLAT side of the motor shaft Tighten the longer set screw against the FLAT side of the motor shaft

    • Make the top of the motor shaft flush with the top of the pulley.

    • Tighten the longer set screw against the FLAT side of the motor shaft

  8. Tighten both set screws well. We do not want these to be loose.

    • Tighten both set screws well. We do not want these to be loose.

    • Tightening well does not mean tightening with unrestrained force. You can strip the set screw threads or its hex head if you use too much force.

  9. Put serrated washers onto four M3x12 screws.

    • Put serrated washers onto four M3x12 screws.

  10. Place the motor onto the Y bracket where it says Y motor adjoins here to this side Align the Y motor connector with the motor contour etched in the acrylic. Align the Y motor connector with the motor contour etched in the acrylic.

    • Place the motor onto the Y bracket where it says Y motor adjoins here to this side

    • Align the Y motor connector with the motor contour etched in the acrylic.

  11. Loosely insert all four screws.

    • Loosely insert all four screws.

    Edit

    • Avoid alignment issues by tightening all the screws at the same time little by little in a diagonal pattern.

    • This is called cross-tightening. All the cool kids do it.

    • Hold the SHORT side of the hex key. This will help you not to over-tighten the screws. You don't need maximum force; you need the right amount of force.

Not all printers come with long and short set screw. Some have two of the same size.

Hi Ian, that's true. That's I added a note "That's nice, but not necessary. If your two set screws are identical, don't worry about it." :-) Thanks for your note!

Filip Goc -

We got to step 3 and realized we needed to sort our hardware out. Other than that, it took about 15 minutes.

Hi Justin. Could you please elaborate on what does 'sorting hardware out' means? As far as I know, we ship JellyBOX with a 'hardware box' with all the parts sorted. Thanks!

Filip Goc -

1. Tell where the pulleys are found (In the hardware box). Identify tools sizes and parts sizes required. This allow faster groups to prepare for the next step. Thread lock says "Shake Well". 2. I think we should mention the pealing of the acrylic with tweezers.
