Every DXF and SVG must work. Can you upload your file here, that I can check it ?

Release notes V3.22

I would like to introduce you again a new version of my program. This time I was engaged with the production of balustrades for historical ship modeling.
The extremely small dimensions (e.g., 4x4x12mm) and nature of these tiny wooden posts necessitate special machining.

In the video I've tried to describe the process of machining the balusters with a little circular saw.

Have fun with GrblGru

Release notes V3.23

Are you still looking for some gift for Xmas ?
If so, maybe I can add an idea for a suitable packaging.
I've created a new Dxf template for a 'Puzzle Gift Box'. There are 6 puzzle pieces that can be put together to a box.
GG provides a Dxf file from all this pieces. So you can import it also to other systems like CamBam, Easel etc.

I've attached some example dxf file. If you are interested to know more, please have a look to the video.

Have fun with GrblGru

Release notes V3.24

the new version, availlable at https://goo.gl/quFpdZ, provides a new 3D model of a very nice lathe.
It's a near 60 years old UNIMAT lathe, updated to a CNC machine by a friend from Austria.
In the attached video I've documented how to create the toolpath and the G-code from an DXF or SVG drawing.

Release notes V3.25

The new version V3.25.0 can now be downloaded from my dropbox at https://goo.gl/7BGkkO
This time I tried to provide a 'trial version' for GrblGru starters.
For this purpose, a menu appears at the start of the program in which you can select the basic purpose.
In addition to the full version, a simple 3D simulation and a G-code sender are available.
So if you want to try GrblGru, I especially recommend the 3D simulation mode, which allows with little effort to simulate existing G-codes files.

I also added new 3D models again. Among other things, a laser. Next time I will report separately about it.

Because I've been often asked to describe what GrblGru actually is, I've created also a document, which attempt to fulfill this request.
Download from my dropbox:

Release notes V3.26

Easter is just around the corner,
and after I added the virtual 3D model of an EggBot to the program some time ago, I now want to provide a real model.
It was important for me to use the normal GRBL with 3 motors. The well-known variant with the servo for pen lifting was therefore eliminated.

Another important point was to keep costs as low as possible. The practical execution is certainly not a mechanical engineering masterpiece.
Expectations of speed and precision must therefore not be set too high. It's more about the principle.
However, the model is hopefully still suitable for teaching important knowledge of CNC technology in a playful way.
(And you can also paint eggs with it)

Reproduction of the model is not only possible with GrblGru, but with any other control system.
If necessary, you can also saw out the plywood parts with a fretsaw. The actual operation of the model is currently only tailored to GrblGru.
But maybe someone can change the construction so that a servo takes over the pen lift again.
This would also make it possible to control the whole thing with InkScape.
Suggestions for improvement are welcome.

Here are the costs for material and software:
----------------------------------------------------
Arduino UNO + CNC Shield 12 Euro
Stepper motors 3 x 2 Euro 6 Euro
Plywood 4mm 2 Euro
GRBL Software 0 Euro
GrblGru Software 0 Euro

I forgot to mention in my last post that the two attached DXf files were saved with metric units.
This means that they are 25.4 times larger than in imperial units.
That's why I saved both drawings again with the factor 1/25.4.
I am not sure that the accuracy will be maintained. Please let me know if it doesn't work.

Release notes V3.27.0

At https://goo.gl/quFpdZ you can download my new GrblGru version V3.27.0 for free, if you like.

This time I have dealt with the Grbl Laser mode. Unfortunately I have to admit that I don't own a laser yet, but I will buy one as soon as possible, because the application possibilities are already great. Because I do not yet have any practical experience myself, a friend helped me to work out the necessary program adaptations for the operation of a laser.
As always, I tried to briefly describe the essentials in the attached video.
Since my friend use his laser to make cosplay costumes, the main focus is on the steps involved in cutting materials.

A short request at the end.
Even a small weak laser can cause irreparable damage to the eyes. Be sure to get laser safety glasses and be aware of the necessary safety regulations.

I have been waiting for a laser version for a long time.
Now I am waiting for the engraving tab with lines.
I've tried to use pocket zigzags before milling with a mill cutter modification in a very small diameter, but it did not always work properly.
