This firmware is for 8 Bit based printers only. If you have a 32 Bit board in your machine check out our Unified 2 Firmware site here: UF2.TH3DStudio.com
Thank you for checking out the Unified Firmware. Sales from our store and donations are what help fund this project and others. We also support the Marlin Firmware project through monthly donations as this is what it is built on top of.
If this firmware helped you out and you are not already a customer please consider making a purchase from our store to help support us or donate below. Happy Printing! Learn about our team here: About Us
How to use the firmware: Read the README file in the package to get started and read the top Configuration.h file for directions.
Setup Change Notes (from video directions):
- EZABL_ENABLE is NOT needed or present anymore in new releases. Only uncomment the probe mount and it will enable the EZABL system.

NOTE: The included library files in our IDE should NOT be updated. There are issues with the latest libraries from Arduino that will result in display corruption. If you have any other Arduino IDEs installed please remove them before using our version to avoid any possible issues when compiling the firmware.
PLEASE NOTE: You must have a bootloader already on the printer to flash the firmware over USB. Printers with the 1284p chip need a bootloader. Here is how to load the bootloader with links to the hardware needed: http://Bootloader.TH3DStudio.com. See the printer support table below to see if your particular model needs a bootloader. Printers that need the bootloader on the support table below have a “ᵇ” after their name.
ALL slicers (Simplify3D, Cura, Slic3r, etc) or anything else that connects to the COM port must be CLOSED for the firmware to be flash. If anything is connected to the COM port when flashing it will fail, typically “access denied” is listed in the error section of the Arduino IDE.
You MUST use the Included Arduino IDE to flash the firmware if on Windows and if you are on a Mac or Linux follow this guide to setup your IDE to work with the firmware if our automated installer for Mac isn’t working on your machine. -> Arduino IDE for Mac OS X Setup Guide

- ᵇ – Printers with this after the name needs a bootloader installed. We have a full flashing package here: TH3D Uno Bootloader Flashing Kit and a guide here: TH3D Bootloader Guide (Video)
- ^^ – The Wanhao D6 has a compact head. The EZABL Mini does not reduce any print space using the mount supplied. You can use the regular EZABL however we do not have any pre-supported sensor mounts for it. The physical hardware works with the D6 board but we do not have a mounting option supplied for it. TLDR; Go with the EZABL Mini (12mm) if you have a Wanhao D6.
- ᴸ - Printers with this after the name need a LCD conversion to work with our firmware and supported products.
- Custom Mount – This means the firmware is set up and ready for the EZABL kit but you will need to locate a probe mount for that particular machine. We may add official mounts in the future but if this note is here you will need to supply your own probe mounting solution. If you have a mount that works with these machines on the stock hotend please email Support@TH3DStudio.com and we’ll get it officially added into the firmware and download package.
- Our support on the EZABL covers the printers in the list above with their original control boards.
- Setting up EZABL on Vanilla Marlin?. The EZABL works like a normally open endstop switch and will physically work with boards running Marlin or RepRap (Duet) but the included support does not cover getting your custom machine setup but support on a custom machine is available at an hourly rate. Otherwise you can always check out our communities for getting the EZABL working on a non-supported board/printer here: Community.TH3DStudio.com

* The BL Touch settings and configuration are provided in the firmware so you can use a BL Touch sensor with our firmware. TH3D Tech Support will not provide technical support for BL Touch users. If you need technical support with an ABL probe our EZABL comes with technical support with it when using this firmware.
The Unified Firmware has been tested with the above features in the “Features” list. Any deviation from the TH3D configurations can cause issues and is not supported. If you are a customer and have made changes in the features our support will have you use our standard configuration to rule out any issues. This is done for stability and quality assurance reasons as well as to minimize possible end-user issues.
The Unified Firmware Package and all files in the said package are provided AS-IS with no warranty or guarantee, use at your own risk. TH3D is not to be held liable for any damages or issues due to using anything in this package. This is provided for anyone to use at their own risk.
If you are an EZABL customer – support on the EZABL kit and the Unified Firmware features is provided free of charge. For MKS Gen L users the support is limited to the EZABL kit itself meaning support for setting up your MKS Gen L machine is NOT included under the EZABL support. Anyone is welcome to use this firmware as it is under the GPL V3 license but there is NO support if you are not a customer. If you contact support and are not a customer you will have the option to purchase support at an hourly rate.
