## Function

The Encoder Knobs are press-fit caps for the RADR wireless remote's rotary encoders. This component:

* Provides an ergonomic grip surface for encoder control
* Press-fits onto the encoder shafts
* Features optional translucent sections for LED backlighting
* Two knobs required per remote (left and right encoders)

## Print Settings

| Setting           | Value      |
| ----------------- | ---------- |
| Layer Height      | 0.12mm     |
| Walls             | 4          |
| Infill Type       | Gyroid     |
| Infill Percentage | 25%        |
| Supports          | Yes - Auto |

<Tip>
  Print with the shaft cavity facing upward for best surface quality inside the bore.
</Tip>

## Multi-Color Printing (Optional)

The knobs include a separate body for the backlight ring area:

| Area           | Purpose                  | Recommended Material    |
| -------------- | ------------------------ | ----------------------- |
| Backlight ring | Shows encoder LED colors | Transparent/translucent |
| Main body      | Grip surface             | Any opaque color        |

## Installation

<Steps>
  <Step title="Prepare the part">
    Remove supports and lightly deburr the bore with a hobby knife or small round file.

    <Check>
      The bore is clean and smooth; no support material remains inside.
    </Check>
  </Step>

  <Step title="Test fit on the encoder shaft">
    Align the knob with the encoder shaft. Do not force it—ensure alignment first.

    <Warning>
      Excessive force can damage the encoder. Apply steady, straight pressure only.
    </Warning>
  </Step>

  <Step title="Press-fit the knob">
    Press straight down until fully seated. Repeat for the second encoder.

    <Check>
      Knobs rotate smoothly and the remote registers encoder turns and clicks.
    </Check>
  </Step>
</Steps>

## Troubleshooting

<AccordionGroup>
  <Accordion title="Fit is too tight">
    * Lightly ream the bore with a small round file or deburring tool.
    * Re-slice with −0.5% to −1% XY scale or use a negative horizontal expansion value.
    * Warm the knob slightly (hair dryer) and press-fit while warm.
  </Accordion>

  <Accordion title="Fit is too loose">
    * Re-slice with +0.5% to +1% XY scale.
    * Add a thin wrap of PTFE/plumber's tape to the shaft as a temporary shim.
  </Accordion>

  <Accordion title="Support marks inside the bore">
    * Increase support Z-distance/interface layers.
    * Switch to tree supports or reduce support density.
    * Orient with the bore up to minimize internal supports.
  </Accordion>
