Raspberry pi with touchscreen and octoprint
I found an old el-cheapo LCD for Raspberry Pi with resitive touch, something like this. Lacking something else to do, with -10°C outside, using a pi with OctoPrint with a touchscreen seems like a decent thing to do. For something close to production, you'll probably want capacitive touch and perhaps something larger than this, but hell, I'm bored.
Stuff needed
- A raspberry pi model 2 or higher. The old 700MHz model 1 has too little CPU and memory - the others will do. As always, you'll need a power supply giving you 5V and at least 2A, preferably closer to 3A.
- A Micro SD card, 4GB or larger - preferably 16-32GB since you'll probably use it to hold some gcode files as well.
- A chassis for the pi and the touchscreen. If using the mentioned screen, something like this should do. All you need is access to a 3d printer, filament and some time.
- Access to a PC and a SD Micro card reader.
- A USB cable to be connected between the pi and the 3d printer. With my Ender 3, it's USB A <-> USB mini, but it may vary.
