    Re: GrblGru: Free CAM and 3D-Simulation for mills and lathes

    Ok, now I've finally got it Thank you for convincing me

    The paths are calculated from the center of the tool, not from the tip. If the infeed is smaller than the radius, the green paths appear below the start line.
    And you are right, this is of course a bug that I need to fix.
    But please give me time. I have a lot to do at the moment and the error is not that serious. It won't break anything, it just needs time.

    Thanks for your help to improve GrblGru

    Hello everyone,

    I finally got around to finishing the last part of the little series about the foam cutter.

    Have fun with it

    Hallo , How I can change Z and X order of machine ? Spindle moved on X platform and X driven by Z axis. Y is table axis

    You can map all axes in the MachineManager.
    To do this, simply enter the desired letters in the right column. After that, do not forget to press the ‘Accept data’ button.
    Note that the designations are only changed in the communication with the controller. The displays in the GrblGru window remain unchanged.

    From the new version v6.0, GrblGru now also offers the option of creating simple geometry objects such as circles, arcs, rectangles and polylines.
    In the video I briefly introduce the various functions.

    Re: GrblGru: Free CAM and 3D-Simulation for mills and lathes

    Hi GRBLGRU

    I just finished my mini lathe.
    I use DCMT insert with 0.2mm radius.
    I realized the diameters are undersized.

    When I change the Corner radius to 0.2 in the tool tab, the contur goes under the real dimension.
    No issue above 0.2mm.

    Your help is very appriciated.

    Awesome tool!

    I've been making more videos in German again recently.
    Perhaps this one is also more generally understandable and interesting for some people.

    Re: GrblGru Troubleshooting

    Another video in German, which also illustrates without text how to machine turned parts on the milling machine.
    It also shows how you can use your milling machine as a lathe.

    Should this update also fix the bug from post #761 or is that a separate issue? I just tested 1.3 and still see the same result.

    @54baseball

    Sorry, I don't understand you. There is no bug described in #761. Are you talking about the milling or lathe program?
    Can you please describe your problem in detail again ?

    Re: GrblGru: Free CAM and 3D-Simulation for mills and lathes

    Thank you - sorry for not being more clear. Here is the comment that I was referencing. I am seeing the same behavior in lathe beta v1.3.

    Sorry, I must have forgotten that. Thanks for reminding me.
    I just uploaded a new beta V1.5.
    Please check if everything is correct now.

    Re: GrblGru: Free CAM and 3D-Simulation for mills and lathes

    As a supplement to my last, more theoretical video, today I would like to show you milling turning in practice. I have chosen a chess piece as a test object, which is intended to represent a possible area of application. Based on the experience gained in the tests, I had to make significant changes to the entire process. (V6.10)

    Although milling turning is certainly no real competition for turning on a lathe, I am pleasantly surprised by how well it works. There are a lot of small turned parts, such as game pieces, handles, furniture knobs, etc., that can be produced very well with this method.

    In addition to the familiar possibilities of a turning axis, milling turning thus offers another convincing argument for sensibly expanding the range of applications of a conventional 3-axis milling machine.

    Unfortunately, the video is only available with German subtitles. I would be very happy if someone would try out milling turning and perhaps even make a video of it.
    Maybe even in English.


    Have fun with GrblGru

    Re: Thread macro for GRBLGRU

    Update: I have created an interactive routine to generate a g33 program for any standard thread (UNC,UNF,UNEF,Metric,NPT) with prompts for depth of cut and thread length (except DOC only for NPT).
    This resides on an inexpensive ESP32C3 mini module, and is accessed via a Terminal program (such as Arduino Serial Monitor, PUTTY or??). The resulting code can be copied and pasted into a
    text file (typically 3x56_5.gco) for a 5mm long 3x56 thread. I'll be making a programmed ESP32 available for a "reasonable" price, and will provide a test prototype unit for postage cost, to the first 5 responders to markotime@gmail.com. Comments?

    Re: GrblGru: Free CAM and 3D-Simulation for mills and lathes

    Double-sided machining of workpieces

    Recently, I had a few small projects where workpieces had to be machined from two sides. Until now, I had always solved this problem using the familiar method with dowel pins.
    However, since there were several fairly small parts that could not be milled on a common plate, I decided to use a different manufacturing method.
    This requires a centering vise, which has the great feature that the center between the clamping jaws always remains in the same position.
    So if you can set the reference point in the Y direction to this position, all you need is a stop in the X direction. This will determine the center of the component.

    I don't know if everyone is already familiar with this method. That's why I would like to briefly introduce it in the video
    Unfortunately, I forgot to mention a possible correction to the Y position of the reference point in the video.
    If a constant offset is always visible on the finished workpiece, the Y axis can be moved in the correct direction by this amount and the reference point can be reapplied.

    I used a new system to create this video. It should be possible to select the language of the subtitles. Please let me know if this does not work.
