Plotter Controller - Web Interface for 6-Axis Plotter

We have an existing 6-axis driver for our plotter. We need to build a simple web interface where users can upload pictures for the plotter to draw. The system uses stepper motors with encoders and limit switches for XYZ axis.

Key Requirements:
- Web interface for image upload
- Image-to-G-code conversion pipeline
- Plotter communication and control
- Support for stepper motors with encoders and limit switches
- Testing and final tuning

Skills Required: Python, Embedded Linux, C#, Firmware Development

This is an ongoing project, estimated 1-3 months.
