What’s in the download?
How to use the firmware: Read the README file in the package to get started and read the top Configuration.h file for directions. EZABL_ENABLE is NOT needed or present anymore in new releases. Only uncomment the probe mount and it will enable the EZABL system.
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

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.

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.
