BIGTREETECH KNOMI 2 Screen for Voron Stealthburner 128 LCD Update

Description

Product Overview

The BIGTREETECH KNOMI 2 Screen is a purpose‑built 1.28 inch LCD touch interface designed exclusively for Voron Stealthburner platforms running Klipper firmware. Constructed from high‑quality polycarbonate and reinforced glass, the display offers a durable, scratch‑resistant surface that withstands the rigors of a busy workshop. Its five‑point capacitive touch panel provides responsive, multi‑finger gestures, enabling users to navigate menus, start prints, adjust temperatures, and control filament extrusion with a simple tap. The unit supports multi‑color UI themes, allowing operators to customize the visual experience to match personal preferences or branding guidelines. Integrated ESP32‑WIFI connectivity powers OTA (over‑the‑air) firmware updates, so the latest features and bug fixes can be applied by dragging a file into a web interface—no soldering or disassembly required. Compatibility is limited to Klipper‑based printers, ensuring tight integration with advanced motion planning, pressure advance, and input shaping capabilities. Technical specifications include a compact footprint of 1.55 × 0.03 × 1.36 inches, a weight of 2.08 oz, and support for both SB2209 and SB2240 CAN‑enabled extruder boards. The device also offers optional Bluetooth 5.0 and an external 2.4 GHz Wi‑Fi antenna for extended range, making it a versatile hub for future IoT expansions such as camera modules, environmental sensors, or wireless charging accessories.

Usage

Designed for makers, engineers, and small‑scale manufacturers, the KNOMI 2 Screen fits seamlessly into the Voron Stealthburner enclosure, replacing the stock LCD with a richer, more interactive display. In a typical workflow, users power on the printer, and the KNOMI 2 instantly presents a clear status screen showing nozzle and bed temperatures, print progress, and estimated time remaining. From this interface, a single touch can pause, resume, or cancel a job, while sliders allow fine‑tuned extrusion rates and fan speeds. The OTA update feature is especially valuable in environments where multiple printers share a network; administrators can push firmware upgrades to all units simultaneously, reducing downtime. Because the screen communicates via CAN bus, latency is minimal, preserving the high‑precision motion control that Klipper provides. The device also shines in educational settings, where students can experiment with real‑time UI customization, adding sensor readouts or custom graphics without needing deep hardware knowledge. Whether operating in a home lab, a makerspace, or a small production line, the KNOMI 2 enhances usability, reduces the learning curve, and streamlines daily printer management.
