Help needed, modified gctrl g-code sender

in Integration and Hardware • 10 months ago

Hello friends, I needed your help to modified the gctrl (g-code sender for CNC Machine that use Arduino)

Yesterday, I found very useful and interesting g-code sender that build on Processing, develop by damellis (David A. Mellis)
I already test the gctrl g-code sender on my CNC Machine, it's run smoothly.
I found it here: https://github.com/damellis/gctrl

I made a decision to make little modification, by adding GUI on the gctrl g-code sender.
this is what its looks like:

but, I have these problems, I hope members can help me how to make it done:

1. How to show file name on the Processing, the location is after "File name:" as shown on the picture above.
2. I have run the g-code sender and the running g-code is shown on the Processing text area. Is it possible to show the running g-code on the interface, the location is on the box below the "File name:" box as shown on the picture above.

The edited gctrl code: http://www.mediafire.com/?4k450e0kxn7phgo

Pre-compiled gctrl (windows-32bit): http://www.mediafire.com/?ailgsxcwxy282dj
Pre-compiled gctrl (macosx-32bit): http://www.mediafire.com/?epu2qcbhamwpp6t
Pre-compiled gctrl (linux): http://www.mediafire.com/?cd5y2gyyh7uxfbt
* I'm sorry I only have Windows OS, its run smoothly on Windows. I hope members can help me try on other platform.

I hope forum members can help me on solving these problems.
I'm sorry still learning tough.

Thank You and Regards,
ariffinastute.

The questions are a bit unclear, I am not sure the code can be useful for those without CNC machine, and I don't click on a "mystery" link (and I have no time to download and unzip some archive; even less adding some one-time-use library).
It is often better to show a simplified version of your sketch, possibly stripping out additional libraries and such.
Now, some people are more patient / have more free time, so you might get somebody curious enough to help more.

Let's see your questions.

1. How to show file name on the Processing, the location is after "File name:" as shown on the picture above.
2. I have run the g-code sender and the running g-code is shown on the Processing text area. Is it possible to show the running g-code on the interface, the location is on the box below the "File name:" box as shown on the picture above.

1. What file name? Can't you just use text()?
2. Not sure what is the "Processing text area". I suppose you mean the console below the code. It is displayed via println(). You need to collect the information printed this way in a single string, and use text() (probably with bound parameters) to display it at the proper place.

Hi PhiLho, thank you for your concern

. I'm sorry for my unclear question.
I'm sorry I still learn Processing, moreover I never learn C/C++. I just get through Processing because it is easy for me to learn this Processing language.

1. I'm referring my first question based on picture below. As we can see on the picture below, on the File transfer box, its show the selected file, which is "/Users/Me/Dropbox/grbl/script/Hello_World_ShapeOko.txt". I'm so sorry, that what I mean for how to show file name on the Processing. Is it possible to show file name on Processing? I already use text(), but it only appear once, just like blink than it disappear.

This is the code to select file:

void mousePressed()
{
//Open File
if (!streaming)
{
    if (mouseX > 380 && mouseX < 404)
    {
      if (mouseY > 55 && mouseY < 79)
      {
        gcode = null; i = 0;
        String file = selectInput();
        if (file == null) return;
        gcode = loadStrings(file);
      }
    }
}
}

2. I'm so sorry for "Processing text area", I read on Processing wiki it show the console as text area. second question also I referring to picture below. As we can see below, it has "console" tab. Is it possible to bring the console below the code onto the GUI, or there is another option to show it. I also already use text(), it also has same problem with question 1. It appear once, just like blink than disappear.

This the code for println() the gcode on the console:

void stream()
{
if (!streaming) return;

while (true) {
    if (i == gcode.length) {
      streaming = false;
      return;
    }

    if (gcode[i].trim().length() == 0) i++;
    else break;
}

println(gcode[i]);
text(gcode[i], 40, 250);
port.write(gcode[i] + '\n');
i++;

}

This is the full code:

import javax.swing.JOptionPane;
import processing.serial.*;

Serial port = null;

// select and modify the appropriate line for your operating system
// leave as null to use interactive port (press 'p' in the program)
//String portname = null;

I think reading the Technical FAQ can be useful for you. Particularly the Sequencing and timing questions / articles.
The text appearing in a blink indicates you just show it outside of draw(), so it is erased the next time draw() is called.
Typically, you have a global variable, eg. named fileName, initialized at "" (empty string), so it displays nothing initially.
This variable is always displayed in draw() (but by default, it then shows nothing).
You use this variable instead of a local variable in the snippet you show.

void mousePressed()
{
//Open File
if (!streaming)
{
if (mouseX > 380 && mouseX < 404)
{
if (mouseY > 55 && mouseY < 79)
{
gcode = null; i = 0;
fileName = selectInput(); // The global variable!
if (fileName == null) { fileName = ""; return; } // Keep showing nothing
gcode = loadStrings(fileName );
}
}
}
}

Thus, the information about the file name isn't lost.
Similar strategy for the console text.

Hi PhiLho, thank you very much. i just got the Idea from your reply. First, I didn't understand what actually the code doing, because I've tried it and it done nothing. I keep Google and found this code:

import processing.serial.*;
Serial myPort;
String portnum;
String outString = "";
String inString = "";
int receivedLines = 0;
int bufferedLines = 8;

void setup()
{
size(400, 300);
PFont myFont = createFont(PFont.list()[3], 14);
textFont(myFont);
println(Serial.list());
portnum = Serial.list()[3];
myPort = new Serial(this, portnum, 9600);
}

void draw()
{
background(0);
text("Serial port: " + portnum, 10, 20);
text("typed: " + outString, 10, 40);
text("received: " + inString, 10, 80);
}

void keyPressed()
{
switch (key)
{
    case '\n':
    myPort.write(outString + "\r");
    outString = "";
    break;

    case 8:
    outString = outString.substring(0, outString.length() -1);
    break;

    case 65535:
    break;

    case '+':
    myPort.write(key);
    outString += key;
    break;

    default:
    outString += key;
    break;

}
if (outString == "+++")
{
    delay(2000);
    outString = "/n";
}
}

void serialEvent(Serial myPort)
{
// inString = "Serial Event Recieved!";
// delay(2000);
int inByte = myPort.read();
inString += char(inByte);
if (inByte == '\r')
{
   inString += '\n';
    receivedLines ++;
    if (receivedLines > bufferedLines)
    {
      deleteFirstLine();
    }
}
}

void deleteFirstLine()
{
int firstChar = inString.indexOf('\n');
inString = inString.substring(firstChar + 1);
}

So, than I understand what do you mean, by looking at coding above and your coding, then I understand the meaning of The global variable!. I put String FileName outside void setup() and void draw(), and follow your code. It's done with flying colours. The filename showed up as shown in picture below:

but the FileName showed was extend, as shown on picture above, how to reduce the extended FileName?

Thank You

String fullPath = "/this/is/some/fine/salad";
String[] splitPath = split(fullPath,'/');
String fileName = (splitPath[splitPath.length-1]);

Use the split() function to extract the last part of the path.

Hi thomashollier, thank you for your reply. I'm really sorry, after 40 minutes I tried and error using your coding. It seems not change. I put the code outside the void setup() and void draw().

and this what happen:

1. the default shown on picture below "salad", If i change from code:

String fullPath = "/this/is/some/fine/salad";

to code:

String fullPath = "/this/is/some/fine/null";

then it will show "null"

2. the FileName not do the split as the coding, it is also keep showing fullpath, as the picture on my previous post.

can you show me where to put the code at the exact line in coding.

Thank You.

The windows directory is "\" instead of "/" so the split wasn't working for you. I think the following will show the filename the way you want it.

Re: Help needed, modified gctrl g-code sender

Hi thomashollier, I'm sorry, I just wake up from sleep.
Thank you very much, its working very nicely.

it shows right name of the file, very beautiful. I'm exciting.

This what happen:

Thank You very much, I appreciate it. I really love it.

Thomashollier, is it possible to put processing console on the processing GUI?

I'm sorry I not mean the whole console will be in the GUI.

this code are reading the gcode:

void serialEvent(Serial p)
{
String s = p.readStringUntil('\n');
println(s.trim());
if (s.trim().startsWith("ok")) stream();
if (s.trim().startsWith("error")) stream(); // XXX: really?
}

and the run gcode will be shown on the console, like this:

G01 X-6.2568 Y39.1225
ok

G01 X-6.1981 Y39.3031
ok

G01 X-6.1119 Y39.4723
ok

G01 X-6.0003 Y39.6260
ok

G01 X-5.8660 Y39.7603
ok

and it keep running until the last gcode line has been sent to the Arduino.

its println() and showed up in the console, I already use text() for this code and it appear once and disappear.
I want to make 8 or 15 line or something like that, that showed up in the GUI:

G01 X-6.2568 Y39.1225 ----> First line
ok                                -----> Second line
G01 X-6.1981 Y39.3031 -----> Third line
ok                                -----> Fourth line
G01 X-6.1119 Y39.4723 -----> Fifth line
ok                               -----> Sixth line
G01 X-6.0003 Y39.6260 -----> Eighth line
ok                               -----> Nineth line
G01 X-5.8660 Y39.7603 -----> Tenth Line

and then, when Eleventh line coming, the First line will not be shown.
ok                               -----> Eleventh line

and it will be shown like this.

ok                                -----> First line
G01 X-6.1981 Y39.3031 -----> Second line
ok                                -----> Third line
G01 X-6.1119 Y39.4723 -----> Fourth line
ok                               -----> Fifth line
G01 X-6.0003 Y39.6260 -----> Sixth line
ok                               -----> Eighth line
G01 X-5.8660 Y3 9.7603 -----> Nineth Line
ok                               -----> Tenth line

It will be like this, this just illustration

Even though there is 500 lines of gcode, the GUI will only show 10 running lines for them to showed up.

Thank You very much
