    I apologize to the administrators for having posted the message a second time, the fact for fear of having posted in the wrong place

    Good morning
    I wanted to ask if it was possible to implement a keyboard function key (for example X axis in SX, CTRL + ) for buttons then allowing the use through a JOYTOKEY program of a JOYSTICK, this could greatly simplify the use of the machine in Manual

    @maximassi

    That's a good idea.
    Please give me some time. I will create a new beta version. Because I don't have a joystick, I would ask you to check it out.

    To your question with the lathe I ask you to create a project file and send it to me. (File\Save project ...) With this I can reproduce the problem.

    Thank you for the availability this is the link x download the file https://drive.google.com/file/d/1UrP...ew?usp=sharing
    I await the version with the changes to take the test

    The reason for the lathe problem is that the workpiece is very small.
    GrblGru works with a grid in order to be able to calculate the GCode as quickly as possible.
    This grid can be set in the settings under 'Delta profile'. The default value of 1mm is too big for your component.
    Set it once to 0.1. If you make the grid even smaller, the result will be more accurate, but then the calculation will take longer.

    In the new beta version V3.42.3 on my website I have now added the Ctrl sequences for your joystick. But they only work if you have activated the focus button before. (see pic)

    I will also send you a private message (PM) with my email address.

    Hello all,

    Hope this is the right place to ask this.
    I started working with GrblGru a few weeks ago, and have got everything (servo's, configuring, limit switches) working with the help off all the info I found.
    One problem I have been trying to solve all day, is that the Resume/Cycle start button doesn't work. The Abort and Feed Hold both work.
    So when typing up a string of G-code and executing it (e.g. 'g1 g90 f100 x1000') and then pressing feed hold it will display the message 'movement has stopped' with the continue and exit buttons. Pressing the Resume button doesn't seem to do anything, forcing me to use the mouse, which isn't desired.

    All switches are wired the same way, and a quick check with a mulitmeter indicates that they're all working as intended.
    I checked the cpu_map.h file to insure that the pin numbers are correct, and they are.

    The switches are wired as following:
    Resume/Cycle start: A10 to GND
    Feed Hold: A9 to GND
    Reset/Abort: A8 to GND

    The switches are all NO type, and are connected to a Arduino Mega 2560.
    Since the other switches are working just fine, I'm suspecting a software bug, but have been unable to pinpoint the issue.

    Any help is much appreciated!

    Edit: Also tried re-soldering the switches, and changing them to see if it was a faulty switch. No luck so far

    Hello GrblGru,

    I'm a bug hunter!
    Today I installed the new version 3.42.8 and found a bug.
    The GrblGru.ini file did not load correctly.
    View screen capture.

    @Bartavus
    Yes, you are right here to ask questions or report bugs to GrblGru.

    This is a problem I haven't had yet because I've never used the hardware switches before.
    If you press one of the hardware switches this information goes directly to the processor software (Grbl, Mega-5X, TinyG etc).
    GrblGru does not get this information ! I can therefore imagine that the running protocol between processor and GrblGru gets confused in this case.
    But first I have to investigate this in detail and ask you to give me time for it. As soon as I have found something I will contact you here.


    @Armando (Bug hunter)
    Thanks for letting me know right away. In the last version a bug crept in.
    I just uploaded a new version V3.42.9.

    @GrblGru
    Alright thanks!

    I started working more with the G-code side of Grbl, and it works fantastic!
    I saw a question about the 'NC (G-code) creator' button in the 3D workspace not working, what was the fix for that? I tried searching the forum but couldn't find anything.

    I'm getting more and more amazed with how complete and well-working the software is, you did an outstanding job on this.

    Hope to get the homing working today and get one step closer to a running lathe :P

    Sorry for double posting, cant seem to edit my previous one.

    Homing works!
    Since I'm using the lathe, I had to change the homing axis sequence in the config.h, so it would start with the X-axis.
    Also played around with the soft and hard limits, and learning about WCS and MCS (I feel like I've just scratched the surface of CNCing).

    A possible bug I noticed (or me misusing the function), when soft limits are enabled the jog buttons in GrbrGru don't work and give an Error 15: "Travel exceeded","Jog target exceeds machine travel. Jog command has been ignored."
    Giving Grbl g-code commands via the terminal still works, and soft limits work as I would expect (moves normally within the limits, as you try to exceed the limits it ignores the command and gives and error).

    Tschüss!

    Congratulations. It looks like you're making very rapid progress.

    Unfortunately, I don't have a quick solution to this problem either. I need to look at it in detail.
    I have not connected any limit switches to my lathe and do not use the reference run.
    The reason for this is that the reference run is no longer valid after changing the tool or the chuck. Or you change the position of the tailstock or ...
    Instead I turn 3-4mm on the workpiece by hand and then measure the diameter with a caliper. Then I know exactly the value for the infeed.

    Have a lot of fun with your CNC lathe.

    Release notes V3.43

    it can happen that you are confronted with tasks that are a little off the main stream and cannot be solved satisfactorily by any of the standard programs.
    In this case you always have the possibility to create the GCode by hand.
    The GCode language is very simple and you can often do a lot with just a few commands.
    This simple structure becomes a disadvantage if you have to program e.g. several runs or more complex things.
    Loops, conditional jumps and parameters are not supported by the standard GCode as it is used by GRBL, TinyG, Mega-5X, G2core etc..

    The new GrblGru version V3.43 now provides an 'Advanced GCode' with the mentioned features.
    The 'Advanced GCode' is translated by the Macro Compiler into the normal GCode. This GCode can then be used normally.

    The video shows some examples.

    Have fun with GrblGru
