repurpose ender3 lcd panel free sample

The inexpensive table serves as a basic structure and must be prepared with an additional bottom plate or three side walls and a door made of acrylic panels*.

High temperatures have a negative effect on the performance of electrical components. Therefore, you should place sensitive components of the printer such as power supply, control boards and digital displays or touch panels outside the housing if possible.

It is made of lightweight honeycomb panels encased in high quality nylon and coated with a fire-resistant material. The front of the cube has a large window that can be opened together with the top plate to gain full access to the printer.

For the purpose of noise insulation, you should consider the respective vibration properties. But a metal case with sound insulation panels in the interior would also be an imaginable solution.

For the hidden ones, I found a good trick which is tapping into the USB to serial chip. Most budget printers have the CH430 chip. With a quick search, I found the schematic. The Tx and RX are at the top and that is what I used for my Ender3 V2.

This companion board also takes care of the power. I noticed the LCD cable has 5 volts and Gnd rails. So I made the board sit between the motherboard and the LCD cable to take advantage of that. Now I don"t have to worry about the power and only left with just 2 pins to solder.

Of course, when you want to try the latest firmware (example fromMarlin), you can do it easily with a 32-bit motherboard. No extra programmer is needed. Just use a microSD card and some simple steps, you will get it updated. You may also need to update the firmware when you upgrade your 3D printer with ABL (Auto Bed Leveling) using CR-Touch, or BL-Touch. Or in some cases, the firmware is corrupted, for example blank LCD, you can actually try to update the firmware.

JyersUI:Releases · Jyers/Marlin (github.com), very nice pre-compiled firmware for Ender-3 V2, for both V4.2.7 and V4.2.2 32-bit motherboard, Standard firmware, Manual Mesh Leveling, ABL, UBL and many more. As Ender-3 V2 comes with an Intelligent LCD, you will most likely need to update the firmware for the LCD too.

Otioss Landscape LCD firmware:Front-Mounted Panel for Ender 3 V2’s Stock LCD Display (otioss.com), another great firmware modification, making your Ender-3 V2 LCD becomes horizontal and comes with 3D case design for your to relocate the LCD to the front of the printer.

The LCD screen will be blank for a while and you should see Ender-3 Logo or Marlin Logo appear. You can further check the firmware version under “About Printer” selection.

Ever since I got Ender 3 v2 (review), I wanted to upgrade a couple of things. As Creality’s firmware doesn’t cover every hardware upgrade that comes to my mind, I have to resort to compiling Marlin firmware myself. Don’t be put off, behind the complex programming lingo, lays a fairly straight forward list of values to change to tailor Marlin firmware to your needs. If you follow this guide, it’s unlikely you screw anything up. Let’s build Marlin 2.0 for Ender3 v2 to enable various upgrades.

I would strongly recommend to use Visual Studio Code and PlatformIO to configure Marlin 2.0 for Ender3 v2 and build your firmware. It takes only a couple of moments to set up, and you will be ready to compile (build your own) firmware.

After upgrading Ender 3 v2 with BL Touch I ended up with an unused Z-stop. I quickly found a way to repurpose it into a filament runout sensor. You can read it all about it here. If you already have a sensor in mind, you can simply enable it by modifying config files.
