Firmware Features

Enhanced Performance – TH3D Studio Unified 2 Firmware is designed to optimize the performance of 3D printers, with features like Input Shaping and Linear Advance delivering smoother movements, reduced vibrations, and improved overall print quality. It incorporates advanced motion planning algorithms to enhance the precision and accuracy of your prints when tuned to your machine.

Easy Installation – The firmware is specifically engineered to be user-friendly and straightforward to install. TH3D Studio provides comprehensive installation guides and support to ensure a hassle-free setup process for both beginners and experienced users.

Advanced Bed Leveling – Our Unified 2 Firmware supports our EZABL Bed leveling kits as well as BLTouch and CRTouch Sensors. Don’t have a sensor? We also have Manual Mesh Leveling added as well so you can use mesh bed leveling without a sensor.

Filament Outage Detection & Filament Changes – Our firmware supports stock sensors (if printer is equipped with them) and our EZOut filament sensors. This means you can print without worrying about running out of filament if you have a sensor on the machine. The firmware also supports M600 commands to do filament changes in sliced files as well as from the printer LCD screen. With an outage detection or filament change event the printer will park the print head and wait for the user to change the filament and then resume with the bed heated so your print doesn’t come off.

Customizability – Unified 2 Firmware offers extensive customization options, allowing users to tailor their 3D printing experience to their specific needs. It provides a wide range of configuration settings, enabling fine-tuning of print parameters, such as acceleration, jerk control, steps/mm, motor direction, PID tuning, and more.

Safety Features – TH3D Studio prioritizes safety and includes multiple features in Unified 2 Firmware to protect your printer and prevent potential issues. These features include thermal runaway protection, which detects heating failures and triggers an automatic shutdown to avoid dangerous situations.

Active Development and Support – TH3D Studio is dedicated to continuously improving and updating their firmware. They actively listen to user feedback, release regular firmware updates, and provide excellent customer support to address any questions or concerns. We patch most bugs that are reported to us in 1-2 business days or less.

Community and Documentation – TH3D Studio has a vibrant and supportive community around their firmware, offering a wealth of resources, including FB groups, discord server, guides, and troubleshooting tips. The availability of detailed documentation helps users understand the firmware’s features and functionality better.

Open-Source Philosophy – TH3D Studio follows an open-source approach, allowing users to contribute to the firmware’s development and customization. This fosters a collaborative environment where users can share their experiences, modifications, and enhancements, benefiting the entire community. TH3D also financially supports the Marlin Firmware Project which our Unified 2 firmware is built on top of.

What do you get? – Included is the full source code for compiling on your computer with Visual Studio Code. This firmware is tested by us on the actual boards and printers. Your purchase helps fund the development of the firmware for this board and others. If you get technical support we also will compile firmware for you if you have issues doing it on your own PC.
