If you choose 90 degrees (landscape), your screen might be upside down.
In my case, I selected PiTFT 3.5" resistive touch (320x480).įor rotation, select 270 degrees (landscape). Select the appropriate option for your screen. If you run into issues, please post in the comments section below. In the near future, I'll update this step with Python setup instructions. Ive updated it for now to reference the new Shell script location so things should continue to work. Update 2/1/20: It appears Adafruit is converting many of their Shell setup scripts to Python so the script in this step was 404ing. If you're using the same touchscreen as me-or a similar one-you can use Adafruit's touchscreen configuration script by following the steps below.Ĭonnect to your Pi once again and run the following commands to launch Adafruit's setup wizard: cd ~ If your touchscreen came with configuration instructions, use those instructions to get things working. If your touchscreen connects via GPIO, you'll need to tell your Raspberry Pi to a) output video to the touchscreen instead of HDMI, and b) use touchscreen input as a mouse.
If you're using the Adafruit 3.5" PiTFT display and want a freestanding touchscreen mount, I recommend checking out this great design by brothers Pedro and Noe Ruiz, the official Adafruit 3D print crew (who, coincidentally, I went to high school with!) If you're using the Raspberry Pi 4 for OctoPrint, be sure to print this remix as well.ĭo you have an Ender 3? I also wrote a full guide to adding a touchscreen to the Ender 3 just for you. You can download the Ender 3 touchscreen model on Thingiverse. It mounts directly to the printer for maximum awesomeness and also houses the Raspberry Pi. My choice for the Ender 3įor my Ender 3, I'm using an excellent model made by designer Tronnic.
Search Thingiverse for touchscreen models to find one that fits your needs. The exact housing you choose will depend on the size of your touchscreen, the screen manufacturer (in some cases), your printer, and how you want to attach it to your printer.
