GcodeInterpreter 0.1.0

G-code Interpreter

Simple .NET G-code interpreter

The G-code interpreter will read a G-code file and produce a GcodeProgram from it.

Setup

Install the GcodeInterpreter package from NuGet.

Install-Package GcodeInterpreter

Add services to DI

services.AddGcodeInterpreter();

Using the interpreter

Inject IGcodeInterpreter into a class and use it to produce a GcodeProgram

public class Class1
{
    private readonly IGcodeInterpreter _interpreter;

    public Class1(IGcodeInterpreter interpreter)
    {
        _interpreter = interpreter;
    }

    public async Task<GcodeProgram> Build(string path)
    {
        return await _interpreter.ParseAsync(path);
    }
}

A produced GcodeProgram contains a Lines property that contains the parsed lines of the G-code file. Each Line contains a Command and Parameters property. A Command is of type Field and the Parameters is of type List<Field>. A Field contains a FieldLetter and Code property that represents a G-code command or parameter.

// Loop through the G-code lines while printing each
// lines command
foreach (var line in program.Lines)
{
    Console.WriteLine(line.Command.ToString());
}

// Print a line as it was in the G-code file
var line = program.Lines[0].ToString();
//M190 S60.000000

// Run the program somehow
foreach (var line in program.Lines)
{
    switch (line.Command.FieldLetter.Letter)
    {
        case 'G':
            DoSomething(line.Command.Code, line.Parameters);
            break;
        case 'M':
            DoSomething(line.Command.Code, line.Parameters);
            break;
    }
}
