Explore 3D printing concepts and tools for creating your own Gopher figurines using Go programming language. Learn how to manage and monitor 3D printers, understand GCODE, and use Go to send commands and gather data. Discover techniques for transforming 3D objects, slicing models, and monitoring print progress. Gain insights into using tools like Telegraf, OctoPrint, and InfluxDB for data collection and visualization. Follow along with practical examples and demonstrations to enhance your understanding of 3D printing processes and how Go can be utilized in this creative hobby.

3D printing? Definition: Construction of a 3D object from a digital 3D model
The FDM Gopher Maker Diagram
The SLA Gopher Maker Diagram
The 3D printer's firmware • Link between software and hardware • Marlin: popular open-source firmware for 3D printers • Takes GCODE as input
What is GCODE? GCode is the programming language used by 3D-printers
Example Movement GCODE . G28
Use Go to send GCODE • Microcontroller has a serial port • Use Go to connect to the 3D printer • Use Go to send GCODE
Define configuration with Termios
Gathering temperature report
