EZOut Kits – Connection Options for Creality V4.X.X Boards – J1 Header and LCD Header

Overview

The Creality V4.X.X boards have 2 different ways to connect the EZOut filament sensor to them with our kits. One uses our LCD adapter header board and the other uses our standard version board. Both achieve the same end result, adding a filament sensor to the printer, but they connect differently and have different firmware settings.

For those that want to DIY a connection, you can also use just a sensor with the J1 header option but this is a DIY thing that requires you to re-pin the cable, this is discussed below. Please note that this is provided as-is and do so at your own risk. TH3D Studio LLC is not responsible for improper re-pinning and/or damage done by the end-user to their EZOut kits and/or control boards.


LCD Header Adapter Board Kits

Back in the days of the “Melzi” boards, we did not have many free IO pins on the board. We developed the EZOut adapter PCB to re-route the LCD beeper pin to a 3 pin header on the EZOut board as well as power lines for the sensor itself. These boards work on the newer V4.X.X boards but you will lose the beeper function on the LCD.

Firmware setup: This method of connecting uses the EZOUT_ENABLE line in our firmware to set it up.

Plugged on to the LCD header of the board

These adapter boards are still sold and if you have an older one from a prior purchase you can still use it on your new V4.X.X board if you upgrade your control board.


Standard Adapter Board Kits – Connects to the J1 Header

The standard adapter board kits are newer and re-wire our EZOut sensor to work with many boards like the MKS, SKR, and Creality boards. These flip around the 5V and signal lines on the sensor to match the pinout on the 3 pin headers found on these boards. The short cable from the adapter PCB plugs into the J1 header on the V4.X.X boards.

These kits come with the sensor 2 cables, adapter PCB, and heat-shrink to encase the adapter PCB once you have the cables connected to it. When using these kits the LCD beeper function is retained as we are not using the LCD header to pull pins and power from like the previous kit version covered above.

Firmware setup: This method of connecting uses the EZOUT_ENABLE_J1 line in our firmware to set it up.


EZOut Sensor Rewiring for the J1 Header – DIY

NOTE: This information is provided as-is and at your own risk. You can damage the JST pins if you are not careful and if you do not re-wire it correctly you can damage your control board. TH3D Studio LLC is not responsible for improper re-pinning and/or damage done by the end-user to their EZOut kits and/or control boards.

If you have just an EZOut sensor whether that is from a previous kit purchase or just the sensor itself you can re-pin the cable to achieve the same function as the Standard Adapter Board Kits mentioned above. This requires removing the 2 outer pins from the 3 pin JST plug and swapping them.

The 2 outer pins are VCC (red wire) and SIGNAL (white wire). If you do not re-pin the cable or use the standard adapter board kit and plug the EZOut into the J1 header you will short out the 5V rail.

NOTE: You are ONLY re-pinning one end of the cable. The other end that goes to the sensor should not be changed.

Firmware setup: This method of connecting uses the EZOUT_ENABLE_J1 line in our firmware to set it up.
