    It's time again for some news in the lathe mode of GrblGru.
    The new version V3.9.0 provides a solution for copying pieces without any expensive 'Lathe Copy Attachments'.

    The piece, you like to duplicate, will be scanned by a simple DIY touch probe. After that the scan points will be used to create an DXF.
    The DXF can be loaded into GrblGru to create a milling job.
    The little video shows how to duplicate a screwdriver tool knob, from scanning until milling.

    Have fun with GrblGru

    Release note GrblGru V3.10

    Recently Grbl has released the great new version V1.1. It provides a lot of new features.
    In GrblGru V3.10. I've made the needed adaptations now.
    In the attached video I've tried to document step by step the way to use GrblGru as free G-Code-Sender for grbl v1.1
    This includes all necessary steps from upload the Grbl-hex-file to the Arduino board until activating the new single step mode in GrblGru.

    I hope this will give especially folks, who start working with CNC, a quick overview about this interesting topic.

    Have fun with GrblGru

    Release note GrblGru V3.11

    I'm loving the new override feature in Grbl V1.1.
    Now it's possible to change the feed rate 'on the fly' while a job is running.
    So you are able to optimize the feed rate by hearing the noise and feeling the vibration of your machine.

    For GUIs, like GrblGru, also the jogging mode is much easier to realize.

    The attached video shows how to use the new features in the GrblGru G-Code-Mode.

    Have fun with GrblGru

    Release notes V3.12

    Last week I tried to drill some holes manually. The result was really disappointing.
    So I've added a new drilling mode into GrblGru. I hope this is useful, also if you need it only to create centerings.
    The short video shows also how to use it in case of drilling 'deep holes'.

    As well as I've added a new 3D model from the little cnc engraving machine 'Link Sprite'. Please note that the dimensions are not correct.
    It's only an example for machines, that have this special axes arrangement.

    Last not least I've fixed zum bugs in the TinyG modul.

    Release notes V3.13

    In the version V3.13 you will find two new templates for drilling.

    1. The first template, called 'Bolt Hole Circle Calculator' evenly distributes a given number of holes on the bolt circle diameter. The position of every hole can be saved in DXF file.

    2. If you like to create a greater passage (e.g. a hole for a motor), which is too deep for milling,
    the template 'Multi Drill Circle' can help you to calculate how many drill holes are necessary to machine the hole.

    In the attached video you can see in which way you can use this both templates.

    When I go to: https://goo.gl/quFpdZ
    the file it wants me to download is named
    GrblGru.7z
    What do I do with a ".7Z" extension file?

    GrblGru.7z is a compressed archive like *.zip files.
    Just download the program '7-Zip' for unzipping. It's free.
    After unzipping you will find the file GrblGru-installerVx.x.x.exe.
    Start this file and follow the instructions. See also for details
    Have fun

    Release notes V3.14

    In one of the last versions I've already shown how to cut styrofoam in the XZ-plane with the milling machine.
    Now I've also added a new mode and a special template for doing that.
    Furthermore the GrblGru machine park has a new member. It's the 3D model from the huge wooden CNC machine of my friend 'Wodin'.
    He needs to cut styrofoam in the YZ-plane for building his pool !

    If you are interested to know how your milling machine can help building a pool, just watch the little video.

    Have fun with GrblGru

    I am very impressed with GrblGru. I am a computer programmer with 35 years of experience, and a CNC Mill user with 15 years of experience. I am considering replacing my Mach3 + Taig Mill setup with GrblGru + TinyG.

    I have one suggestion and one problem, with version 3.14.0

    The suggestion is that the ESC key should activate the Stop function. When something is going wrong, you often do not have time to use the mouse.

    The problem is that the "Show PreView" button is not active after a GCode file is loaded. One of your videos says that GrblGru can preview external GCode files, but I cannot see how to do that with V13.14.0. PreView works with DXF, but not with Gcode.

    Thank you for any help you can offer.

    A GrblGru model file for a Taig CNC Micro Mill is attached. It is fairly accurate as it is derived (simplified) from an extraordinarily-complete 3D model of the Taig mill that I found in a Taig forum.

    Here are the machine.dat settings.

    [Taig]
    xplus=300.0000000000
    yplus=140.0000000000

    vToolPosx=0.0000000000
    vToolPosy=0.0000000000
    vToolPosz=169.0000000000

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

    I tried using GrblGru to stream GCode to a grbl1.1e laser engrave. It was unreliable. The grbl controller would report different errors (sometimes 24, sometimes 33) after a variable number of lines. I think that the sender is overflowing grbl's buffer causing grbl to misinterpret commands.Very infrequently it would work, getting to the end of a 752 line GCode program, but usually it would fail.

    I tried several other grbl sender programs with that same GCode file and the same hardware, and they all worked correctly every time.

    I used the "dummy" machine definition. I tried with both verbose and non-verbose output in the controller window, and with the controller windows hidden. I also tried turning off all the displays. Nothing helped.

    @wmb

    first of all, apologies for the delay in responding. I don't know why, but I did not receive a notification for your message. Saw just today your message on youtube

    I'm also very impressed about your 3D model 'Taig'. Great work. If you allow I would like to add it to my program for common use.

    I'll do my very best to fix the error, that you get with grbl V1.1e. Therefore I've sent you a PM with my email address.
    Maybe you can send me some details (like screenshots from the error messages)
    I'm working with Grbl V1.1f without any problems. So I'm sure, together we will found the reason for this problem.

    Release notes V3.15

    Are you looking for a remote control for your milling machine ?
    Again 'TennesseePIlot' has a good idea for this, and I've tried to realize it.
    See in the 5 minutes video how to get a remote control keypad for less than 20 dollar.

    Have fun with GrblGru

    Release notes V3.16

    The new GrblGru Version is ready for downloading at https://goo.gl/quFpdZ
    The main focus is set again on the 4th axis. From now this axis is part of the 3D model and can be designed by the user.
    As example for this type of machines we have 2 new models in GrblGru.
    The first one is used only for demonstration. It's a ShapeOko3 with a 4th axis, placed in a square cut-out of the wasteboard, which allows machining of bigger workpieces.
    The second model I've got from a GrblGru-friend, who has designed a pretty cool engraving machine only with X, Z and A axis. It can be used for engraving a cylinder.

    Have fun GrblGru

    Release notes V3.17

    in the new version at https://goo.gl/quFpdZ I've looked at the language selection.
    Again I've created a short video that describes how to add a new language to GrblGru.
    Maybe you can use it to correct my bad english.

    It would be great if someone would create a text file with a language, that is not yet available in GG and would share it with all users.
    I would include these from the next version with in the installation.

    Have fun with GrblGru

    I'm very glad that I can now also provide GrblGru with Spanish language. See https://goo.gl/quFpdZ for free program download
    Many thanks to 'VCB' and 'EL PATRON 809' for the translation and the permission to share it with all users.

    again I can proudly report a GrblGru version with another language.
    From today I can provide also the Hungarian language. Many thanks to my friend Jozef for his great work.
