gcoder

Overview

The gcoder Go package can be used to generate g-code for the Snapmaker A350 device. This is all part of a project to make operations on that device fully scriptable. Using this package, one can make g-code files runnable on the device, either through the Snapmaker official software, or a tool like snappy.

Example

The examples directory contains an example of using this zappem.net/pub/io/gcoder package. When run as follows,

$ go run examples/stripes.go
2025/07/05 22:08:25 generated "stripes.nc" and "stripes.nc.png"

it generates a stripes.nc g-code file for use with the Snapmaker, and a PNG image file:

This is the image of what is rastered by the 1.6W Snapmaker A350 laser device when running the generated stripes.nc g-code file. Note: the small red/black X mark(s) in the bottom left of that image refer to the expected work origin position. The red mark (obscured by the black one in this case) marks the work origin at the start of running the job, and the black one is the work origin at the end of the job. For jobs that change the work origin, these two marks will differ in location.

Plans

Only bug fixes as needed.
