This software acts as a mediator between the frontend and Ender 3 Pro using Printrun module. It listens to below key shortcuts and OSC messages to issue print instructions to the 3D printer. Started development as the final project for MAT594X Computational Fabrication @ UC Santa Barbara.
| Key | Description |
|---|---|
esc |
Shuts down |
t |
Set temperature to 200/50 |
r |
Auto Home and move to first layer |
e |
Clear material from nozzlehead (extrudes on the side) |
| Identifier | Parameters | Description |
|---|---|---|
/move/extrude |
XYZF | Moves the nozzle head to XYZ (mm) with F rate (mm/min) while extruding material |
/move |
XYZF | Moves the nozzle head to XYZ (mm) with F rate (mm/min) |
/extrude |
- | Extrudes some filament in-place and hop down |
/retract |
- | Retracts some filament and hop up a little |
/req/nozzle_pos |
- | Echoes nozzle position back on (/PY/n_pos XYZ) |
TODO |
- | Echoes nozzle temperatures back on (/PY/temp BBNN -- bed_current, bed_target, ...) |
TODO |
- | Echoes printer connection status (/PY/connected T) |

> pip install python-osc # osc library
# on windows
> python .\main.py --serial=COM#
# on macos
$ python main.py --serial=/dev/ttyUSB## arguments: ip and port number of OSC server, listen port, and printer serial port
> python .\main.py --ip=127.0.0.1 --port=12000 --listenport=5876 --serial=COM4- Note: You can find the serial port in your system settings.
- Note 2: MacOS users might need to allow Python in accesibility settings to be able to use keybindings.
Tested on:
-
Windows 10 with Python 3.7
-
Ubuntu 18.04 (in WSL) with Python 3.7
-
Ender 3 Pro
