PLEASE NOTE: All EZBoards ship with a test firmware that is for testing the boards. You must flash firmware for the machine you are installing it in for the board to work.

Do NOT use a Pin 27 or EZOut board when using a BL Touch with the EZBoard. This can damage the board and will not be covered under warranty. Use the SERVO header on the EZBoard for connecting a BL Touch. Refer to the BL Touch installation materials to match up the 3 pins (VCC, GND, and Signal) to the respective pins on the SERVO header on the EZBoard.

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.
