3D Printing Gophers with Go
summary
Uses Go to do four concrete things: a sdfx STL generator creates a gopher model saved as an STL, a Raspberry Pi opens a serial port and sends serial G-code to Marlin to home and move axes, M155 reports are parsed and pushed as M155 temperature polling every 2s into InfluxDB for live charts, and a Telegraf external plugin for OctoPrint polls layer progress and filament then feeds Influx. The 6‑hour FDM gopher prints successfully and the pipeline proves end‑to‑end.
