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

Parse with regular expression

Send temp to Influxdatabase Line Protocol

Use Go to create a 3D model?!?

Transforming 3D objects Use a 4x4 transformation matrix and 3D vectors • func Translate3d(v V3) M44
