problems with Universal Gcode Sender

Hi
As I'm building a cnc router I have an Arduino Uno with a GRBL shield controller on top of it. I've set up the GRBL and got it connected to my desktop computer and its communicating with Coms 3.

I uploaded the Universal Gcode Sender to the GRBL folder in the Arduino but when I click on the jar file nothing happens. I've already installed Java and its working, but the gcode sender doesn't materialize and I don't know why.

I can't think of anything else to do so I'm here looking for some help. Perhaps I've uploaded it to the wrong folder, I don't know.

Any help here would be great.

Michael.

I use the start-windows.bat file to run it.

The GCode sender is a PC program - not an Arduino program. Why would you put it in any Arduino directory?

Have you the Java JVM installed on your PC?
Do you know how to run a Java program?

Hello Brian
Thanks for answering my question. I was led to believe that the Gcode Sender was suppose to go in the GRBL folder.

I got this from NYC CNC Youtube video (DIY Arduino CNC Machine with GRBL Shield - Setup Tutorial! - YouTube).

I have installed Java from Sun before I started setting up the GRBL shield.

You must think I'm a right idiot Robin, Sorry about that. My broadband has been down for 4 days and when I sent the post it was two minutes to 6 pm and the news was on. I was in a rush.

Yes to the first question and no to the second.

I'm relatively new to cnc and its a bit of a learning curve at 70. I started this because I was bored and wanted a hobby. Perhaps I should have bought a train set instead.

I bought all the parts of this cnc router and am slowly putting it together, but the electronics are proving a little harder than I first thought.

I would appreciate any help you can offer.

Michael.

I am not an expert of Java - I have dabbled in it once or twice.

The instructions here say

To run simply unzip the .zip file and double click the .jar file. On some platforms you will need to run an included start script.

Note for MAC users: For version 1.0.8 and earlier you may need to create a "/var/lock" directory on OSX to fix a bug in the serial library. To do this open the Terminal application and run the following two commands:
sudo mkdir /var/lock
sudo chmod 777 /var/lock

Have you tried that?

In my experience Java programs work from any directory.

You can check your Java installation by typing java -version in a command window. If that does not work it means Java is not properly installed.

What PC operating system are you using.

Hello Robin

I'm using Windows 7 (64bit)

I've managed to open G code Sender 1.0.8 (I started out with 1.0.9, don't know why that wont work and 8 does)

These are the settings on the g code sender, there the same on the GRBL shield.

Port 3

Baud 9600

Firmware GRBL

But as soon as I press 'open' I get this (see Attachment)

Now this is strange. I went to switch everything off after I sent you my reply and as I turned off the serial monitor window the lights on the GRBL board flickered momentarily, so I pressed the open button on the Gcode sender and it came alive and I was able to make Y stepper motor go forwards and backwards by pressing its button.

I only attached one stepper motor to the GRBL board, if one works, they will all work.

Have you heard of that before.

Michael.

The readme file says this:

Run the stand-alone distribution from the command line using:
java -jar -Xmx256m UniversalGcodeSender.jar

If your are using GRBL v0.9 then the default baud rate is 115200, v0.8 and earlier was 9600.

I tried that and it worked at first, but it disapeared after my last visit.

Anyway thanks to all for your help as the Gcode sender is up and working now.

Cheers

Michael.

I think you (accidentally or otherwise) uploaded a different image or a different copy of the same image and broke the link.

It would actually have been better if, in the first instance, you had posted the message as text rather than an image.

I used universal gcode sender v 1.0.8 & it worked fine.when i open my pc next day to complete rest of work on cnc it already stopped working.i tried reinstalling java & ugs software it doesn't work.i also tried batch file still hard luck.the batch file shows unable to locate "resources/massage bundle_en.properties"

I never understand why people tag questions onto the end of an existing Thread without carefully reading all of the Thread first. In this Thread Reply #12 clearly says NOT to post text as a picture.

Also, from your picture it seems you are using Windows. The rest of this Thread is about problems on a MAC,

And, sorry, I know neither Windows nor Mac - I use Linux.

Still a relevant topic....

I just encountered the EXACT same issue.

Once I went back and downloaded Universal G Code Sender version 1.0.8 it worked

2018... Me too...

EXACT the same issue.

It was working great and from one moment to other, just didn't open anymore.
I'm using Universal G Code Sender version 1.0.8 on windows 8.1.

I did reintal java, download again gcode sender and nothing...

Someone can give us a direction tu run?

Just a funny thing,

First I double clicked UniversalGcodeSender.jar (Version 1.0.8) and not appears in screen.
After read this post, I downloaded UniversalGcodeSender-v2.0.0-stable, unziped it and double clicked UniversalGcodeSender.jar (Version 2.0.0 stable) and it is working (appears in the screen at least).
Now I'm trying to delete Version 1.0.8 folder and it says it's not possible because the UniversalGcodeSender.jar is oppened on Java(TM) Platform SE binary.

Interesting and threatfull for me.
