@Athena show how to read the lines of a gcode file in javascript in synthiam arc. Because no example of a gcode file was given, here is a 3d printer gcode file. I removed the details about the extruder so it'll merely be cartesian coordinates.

Because gcode files store what ever you want (ie several dimensions), you'd have to define what goes into it. It's up to you to determine what goes in and that determines how to parse it.

; This is a comment in the G-code file
; G-code example for a 3D printer

G21 ; Set units to millimeters
G90 ; Use absolute positioning

; Home all axes
G28

; Start of print
G1 Z0.2 F1200 ; Move nozzle to start height
G1 X10 Y10 F3000 ; Move to the start point
G1 X100 Y10 F1500 ; Draw a straight line
G1 X100 Y100 ; Move in Y direction
G1 X10 Y100 ; Move in reverse X direction
G1 X10 Y10 ; Complete the square

; End of print
G28 X0 Y0 ; Home X and Y axes

; End of file

After thinking about it for a minute Javascript is already in plain text format. ARC is very good at getting axis to locations. It would be nice to download a Gcode tell which axis is which and have it work. I know that can get a 4axis driver to do it but then I'd have to reconfigure the wiring off the arduinos and onto the drivers. This would allow me to do not just 4 axis but up to 128 axis at a time(which is very unlikely) but it just shows the new ability it could have.

I was also thinking: You could use the Inverse Kinematics robot skill to move the end effector to the Cartesian coordinates in the Javascript that parses the file.

To achieve this, you can create a JavaScript script in ARC that reads a G-code file, parses it into a multidimensional array, and then uses the Inverse Kinematics robot skill to move the robot arm to the specified Cartesian coordinates. Here's a step-by-step guide on how you can do this:

Step 1: Read the G-code File

First, you'll need to read the G-code file and store its contents in a variable. You can use the File.readAllText() function to read the file.

var gcodeContent = File.readAllText("path/to/your/gcodefile.gcode");

Step 2: Parse the G-code into a Multidimensional Array

Next, you'll parse the G-code content into a multidimensional array. Each line of the G-code will be split into its components (e.g., G1, X10, Y10) and stored in the array.

var gcodeLines = gcodeContent.split("\n");
var gcodeArray = [];

for (var i = 0; i < gcodeLines.length; i++) {
    var line = gcodeLines[i].trim();
    if (line && !line.startsWith(";")) { // Ignore comments
        var parts = line.split(" ");
        gcodeArray.push(parts);
    }
}

Step 3: Process the G-code Commands

Now, you'll iterate over the gcodeArray and process each command. For this example, we'll focus on moving the robot arm to the specified X, Y, and Z coordinates.

for (var i = 0; i < gcodeArray.length; i++) {
    var command = gcodeArray[i];
    if (command[0] === "G1") { // Check if it's a move command
        var x = null, y = null, z = null;
        
        for (var j = 1; j < command.length; j++) {
            if (command[j].startsWith("X")) {
                x = parseFloat(command[j].substring(1));
            } else if (command[j].startsWith("Y")) {
                y = parseFloat(command[j].substring(1));
            } else if (command[j].startsWith("Z")) {
                z = parseFloat(command[j].substring(1));
            }
        }
        
        // Use the Inverse Kinematics  robot skill to move to the position
        if (x !== null && y !== null && z !== null) {
            ControlCommand("Inverse Kinematics Arm", "MoveTo", x, y, z);
        }
    }
}

Step 4: Execute the Script in ARC

Finally, execute this script in ARC to read the G-code file, parse it, and move the robot arm according to the G-code commands.

Notes:

• Make sure to replace "path/to/your/gcodefile.gcode" with the actual path to your G-code file.
• Adjust the parsing logic if your G-code file has different formatting or additional commands.
• Ensure that the Inverse Kinematics robot skill is properly configured to match your robot arm's setup.

This script provides a basic framework for parsing G-code and controlling a robot arm using ARC. You can expand upon it to handle additional G-code commands or integrate it with other robot skills as needed. If you have any questions or need further assistance, feel free to ask!

@athena now create the script that will print out the values rather than sending them to the inverse kinematics robot skill

Certainly! Here's a script that reads a G-code file, parses it into a multidimensional array, and prints out the X, Y, and Z values instead of sending them to the Inverse Kinematics robot skill. This will help you verify that the parsing is working correctly.

// Read the G-code file
var gcodeContent = File.readAllText("path/to/your/gcodefile.gcode");

// Split the content into lines
var gcodeLines = gcodeContent.split("\n");

// Initialize an array to store the parsed G-code commands
var gcodeArray = [];

// Parse each line of the G-code
for (var i = 0; i < gcodeLines.length; i++) {
    var line = gcodeLines[i].trim();
    if (line && !line.startsWith(";")) { // Ignore comments
        var parts = line.split(" ");
        gcodeArray.push(parts);
    }
}

// Process the G-code commands and print the values
for (var i = 0; i < gcodeArray.length; i++) {
    var command = gcodeArray[i];
    if (command[0] === "G1") { // Check if it's a move command
        var x = null, y = null, z = null;
        for (var j = 1; j < command.length; j++) {
            if (command[j].startsWith("X")) {
                x = parseFloat(command[j].substring(1));
            } else if (command[j].startsWith("Y")) {
                y = parseFloat(command[j].substring(1));
            } else if (command[j].startsWith("Z")) {
                z = parseFloat(command[j].substring(1));
            }
        }
        // Print the X, Y, and Z values
        if (x !== null || y !== null || z !== null) {
            print("Move to: X=" + (x !== null ? x : "N/A") + ", Y=" + (y !== null ? y : "N/A") + ", Z=" + (z !== null ? z : "N/A"));
        }
    }
}

Explanation:

• Reading the File: The script reads the G-code file using File.readAllText().
• Parsing the Lines: It splits the file content into lines and then parses each line into its components, ignoring comments.
• Processing Commands: For each G1 command, it extracts the X, Y, and Z values and prints them.
• Printing Values: The script prints the X, Y, and Z values for each move command, showing "N/A" if a coordinate is not specified.

Notes:

• Replace "path/to/your/gcodefile.gcode" with the actual path to your G-code file.
• This script is designed to handle basic G-code commands. You may need to adjust it for more complex G-code files or additional commands.

@Athena, give me the list of commands that gcode uses. G1 is goto? What else is there for commands in a gcode file.

G-code is a language used to control CNC machines,3D printers,and other automated tools.It consists of a series of commands that instruct the machine on how to move and operate.Here are some of the most common G-code commands you might encounter:

Common G-code Commands

• G0: Rapid positioning. Moves the machine quickly to a specified position without regard to the path taken.
• G1: Linear interpolation. Moves the machine in a straight line to a specified position at a controlled speed.
• G2: Circular interpolation, clockwise. Moves the machine in a clockwise ARC to a specified position.
• G3: Circular interpolation, counterclockwise. Moves the machine in a counterclockwise ARC to a specified position.
• G4: Dwell. Pauses the machine for a specified amount of time.
• G17: Select XY plane for circular interpolation.
• G18: Select XZ plane for circular interpolation.
• G19: Select YZ plane for circular interpolation.
• G20: Set units to inches.
• G21: Set units to millimeters.
• G28: Return to home position.
• G90: Absolute positioning. Positions are specified relative to the origin.
• G91: Incremental positioning. Positions are specified relative to the current position.
• G92: Set position. Sets the current position to specified coordinates without moving the machine.

M-code Commands

M-codes are used to control machine functions that are not related to movement:

• M0: Program stop. Pauses the machine until the operator resumes it.
• M1: Optional stop. Similar to M0, but only pauses if the optional stop is enabled.
• M2: Program end. Ends the program.
• M3: Spindle on, clockwise.
• M4: Spindle on, counterclockwise.
• M5: Spindle stop.
• M6: Tool change.
• M7: Mist coolant on.
• M8: Flood coolant on.
• M9: Coolant off.
• M30: Program end and rewind.

Parameters

G-code commands often include parameters that specify positions, speeds, and other settings:

• X, Y, Z: Coordinates for movement.
• I, J, K: Offsets for circular interpolation.
• F: Feed rate (speed of movement).
• S: Spindle speed.
• T: Tool number for tool changes.

These are some of the most common G-code and M-code commands. The exact commands and their meanings can vary depending on the machine and its firmware, so it's always a good idea to consult the documentation for your specific machine or software.
