KlipperKontrol

Industrial Android control panel for Klipper 3D printers.

Dedicated touchscreen interface for Moonraker-powered printers.

---

Overview

KlipperKontrol is a touchscreen-oriented Android application designed to control Klipper-based 3D printers through the Moonraker API.

Unlike Fluidd or Mainsail, KlipperKontrol is designed as a dedicated industrial control interface:

• minimal,
• readable from distance,
• fast,
• tactile,
• workshop-oriented.

The goal is to transform an Android tablet into a real industrial 3D printer control panel.

KlipperKontrol is ideal for:

• Android tablets,
• Raspberry Pi touchscreens,
• wall-mounted printer dashboards,
• dedicated Klipper control stations,
• industrial-style 3D printer interfaces.

Android DNS Issue

Some Android devices using:

• custom DNS,
• ad blockers,
• private DNS,
• VPN DNS filtering,

may block GitHub release downloads or local Moonraker HTTP connections.

If APK downloads fail with errors such as:

ERR_SSL_PROTOCOL_ERROR

try:

• disabling Private DNS,
• disabling DNS filtering,
• disabling adblock DNS,
• or temporarily switching back to automatic DNS.

This issue is unrelated to KlipperKontrol itself and is caused by Android network filtering.

ETA System

KlipperKontrol uses:

• dynamic ETA calculation,
• moving average,
• ETA smoothing,
• anti-spike filtering.

This creates:

• stable estimates,
• cleaner UI behavior,
• more realistic print times.

APK Build

Install EAS CLI

npm install -g eas-cli

---

Expo login

eas login

---

Configure EAS

eas build:configure

---

Generate APK

eas build -p android --profile preview

---

Android HTTP Support

KlipperKontrol requires local HTTP access to Moonraker.

Your app.json must contain:

"plugins": [
  [
    "expo-build-properties",
    {
      "android": {
        "usesCleartextTraffic": true
      }
    }
  ]
]

And install:

npx expo install expo-build-properties
