As part of my upgrade of my old Anycubic i3 Mega Pro to Klipper, I designed this bracket to affix a 3.2" ili9341 tft touchscreen in place of where the original LCD is located. I like having some of the basic controls right on the printer rather than having to get my phone out, and the ili9341 was part of a super cheap impulse buy awhile ago so time to put it to use. In order to use and install this, you will of course need to have your own 3.2" ili9341 display and know how to connect it to a Rasberry/Orange/Banana Pi running Klipper and Klipperscreen. On the plus side, removing the old display does free up UART3 on the system board for internal serial communication for Klipper.
I printed the LCD holder in ABS for my final fit (mostly because the PLA I was using was running in another machine and I'm impatient), but all prototyping was done in PLA which ought to work fine as temps are not that high internally. Even the installer tool was done in PLA and worked for getting the top screws in without swearing too much.
Installation
Preformed on my Anycubic Mega Pro, I can't guarantee that other models are identical as I don't own them, but step files are included for anyone that needs to mod them.
- Remove the old display
- Re-install two of the screws into the top two screw posts. I've made a super small installer tool for this (stl and step included) as the clearance is really, really tight unless you pull the power supply and mainboard. You don't need these super torqued down.
- Install the new LCD into the LCD holder using M2x4mm screws. They should just self tap into the holes. The bracket is designed so that you can place the TFT screen into the bracket itself either way, useful if you've messed up your rotation. The bracket itself will only fit in the case one way though.
- Install the LCD bracket by wiggling it in and over the two screws you reinstalled, and then align the other two posts and pull the bracket downward a bit.
- The two LCD clips are designed to fit to a particular side and swing in after latching under the top screw (you can see this in action in one of the pictures). You can then install the bottom screw to secure each clip.
- Connect your display cables
