3d-printer-controller

Control your printer remotely with a Raspberry Pi!

Caution

• Using the app makes your printer use relative mode (G91). This means a "Move to x" order will be interpreted as "Move by x". For example, "G0 X10" will "MOVE BY 10", NOT "MOVE TO 10"
• For safety, make sure you've enabled EMERGENCY_PARSER in your printer's configuration! Otherwise, "STOP" won't work. You can still use every other feature though.
• Hitting endstops WILL NOT stop the printer!
• This is a largely untested prototype, I do not take responsibility for any damage your printer might take. Use at your own risk!

Installation

There are 2 components of this app:

• A server you run on a Raspberry Pi and connect to your printer
• GUI app you interact with

So, things you'll need:

• FDM 3D printer
• Linux-based Raspberry Pi (for ex. 4B)
• PC (Windows works, Linux should work, no idea about Mac)
• A local network, which manages the RPI and PC (Directly connecting through an Ethernet cable should also work).
• Any USB cable that can connect your RPI to your 3D printer

Raspberry Pi Installation

• Connect your RPI to your 3D printer via USB.
• On the RPI, install Flask (run pip install flask).
• Copy print_server.py to your RPI.
• Navigate your terminal to that directory.
• Run export FLASK_APP=print_server.
• Run flask run --host=0.0.0.0.

GUI app installation

• switch back to your PC
• get curl
• Everything inside desktop-app is a raw Qt creator project. Import it there.
• Put your RPI's local IP inside put_your_local_ip_here.txt.
• Build and run your project!

You should be able to send commands now!
