Tower is a custom apparatus designed and built by Junhee Won, an undergraduate scientist and engineer at KAIST. Tower Dashboard is supporting service of Tower, providing control of extruder/fiber motors and heater via web service.
Tower Dashboard is developed for Raspberry Pi with Docker.
The updated Software -specifically everything related to the server/User interface has been written by 2JS, an undergraduate software engineer and developer at KAIST. Full Acknowledgements to his contributions are due.

This project is created as a replacement of tower-server worked by EOMMINHO. The need of replacement is introduced to change the server from a PC to Raspberry Pi, since using a PC solely for this very light service is wasting too much hardware resource.
At first, we tried to port the original tower-server for Raspberry Pi (which is arm64 based), but some nodejs dependencies failed on Pi. So we rewriten entire server in python. (Of course, not exact translation)
We brought arduino-side code and communication protocol unchanged, which may differ in future.
Currently, device mapping is not located automatically, and hardcoded in .env by hand. We'll resolve this by implementing identification step in communication protocol so that arduino tells which it is.
Master would be able to change the limit range of device value(speed or temperature) in future. Currently they're hardcoded.
Arduino connection goes randomly unresponsive only if their speed is 0. If they're not, it seems staying responsive. Resetting arduino temporarily resolves the issue.
