A modern touch interface for Klipper/Moonraker 3D printers
Your printer can do way more than your current touchscreen lets you. Bed mesh visualization, input shaper graphs, multi-material management, print history — it's all trapped in a browser tab. HelixScreen puts it at your fingertips.
Fast, beautiful, and built for every Klipper printer — from a Creality K1 to a tricked-out Voron or RatRig.
Release Candidate — v0.99
On the doorstep of 1.0 (targeting early April 2026). Multi-page home screen, exclude object map, temperature graph, Creality K2/CFS support, tool changer widgets, and preheat macros — plus dozens of crash fixes.
Tested on: Voron 2.4 (Raspberry Pi 5), Voron 0.2, Doron Velta, RatRig V-Core, Flashforge AD5M Pro (Forge-X firmware), QIDI Q1 Pro, Sovol SV06, Sovol SV08, Creality K1C, Creality K2 Max
Raspberry Pi: Both 64-bit and 32-bit Raspberry Pi OS are supported (Pi 4, Pi 5, CM4, Zero 2 W).
QIDI: Supported with auto-detection heuristics and print start profile.
Flashforge: AD5M/Pro (Forge-X firmware), AD5X (ZMOD firmware).
Creality: Sonic Pad, K1/K1C/K1 Max, and K2 Max binaries are included. CFS (Creality Filament System) support is in progress.
Snapmaker U1: Cross-compile target with 480x320 display support.

Run these commands on your printer's host computer, not your local machine.
SSH into your Raspberry Pi, BTT CB1/Manta, or similar host. For all-in-one printers (Creality K1, K2 series, Flashforge AD5M/Pro), SSH directly into the printer itself.
One-line install (Raspberry Pi, Creality, QIDI, Sovol, and more):
curl -sSL https://raw.githubusercontent.com/prestonbrown/helixscreen/main/scripts/install.sh | shThe installer auto-detects your platform, downloads the correct binary, sets up the service, and launches the first-run wizard. Updates are just --update:
curl -sSL https://raw.githubusercontent.com/prestonbrown/helixscreen/main/scripts/install.sh | sh -s -- --updateFlashforge AD5M/Pro: We provide a ready-made firmware image (Forge-X fork with HelixScreen pre-configured) — just flash from a USB drive. Or install manually on an existing Forge-X/Klipper Mod setup.

Is HelixScreen production-ready? Release candidate status, approaching 1.0. Core features are stable with 317 test files and opt-in crash reporting. Suitable for daily use on any Klipper printer.
How is this different from GuppyScreen/KlipperScreen? More features, way less resource usage (~10MB RAM vs ~50MB for KlipperScreen), and actively developed. See the comparison table.
Which printers are supported? Any Klipper + Moonraker printer. 68 models in the auto-detection database spanning Voron, Creality, QIDI, Anycubic, Flashforge, Sovol, RatRig, FLSUN, Elegoo, Prusa, and more. The wizard auto-discovers your printer's capabilities even if it's not in the database.
What screen sizes are supported? 800x480, 1024x600, and 1920x480 (ultrawide) are fully supported with auto-detecting layouts. Display rotation (0/90/180/270) is supported with auto-detection. Smaller displays like 480x320 (Snapmaker U1) are a work-in-progress.
What multi-material systems work? AFC (Box Turtle), Happy Hare (ERCF, 3MS, Tradrack, Night Owl), ValgACE, ViViD, Creality CFS, and tool changers (viesturz/klipper-toolchanger). Full Spoolman integration for spool management.
