Hi again GG, please excuse me for pestering you with many post but I am facing some problems that would like to comment (there are two more posts before this one, please do not miss them).

- I cannot see the checking boxes in the 2D menus nor select any of them.
- I cannot open the "NC (G-Code) Creator" menu.
- I cannot see the menu on the right of the screen that I saw in some of your videos.

When i import a DXF file, the software generates the 3D model rotating the curve. Then I can see the 3D representation and also the curves present in the DXF file but placed with an offset between them... (???)

I am attaching a couple of screen shot to show you what I am seeing.

Thanks in advance for your help and guidance!

Thanks for your suggestions

- To the problems
I have at some point adapted the lathe operation to the milling operation. This means that the operation is now the same or at least similar in both operating modes.
That's why you may have seen older videos. I just made a short video for someone else. Have a look here: https://www.dropbox.com/s/fah20myheoq9v ... e.mp4?dl=0
The video shows a machine with the Z-slide in the back. Don't let it get you wrong. After loading the DXF file everything is normal again.

If you want to test something, choose the tool 'parameter tool'. This is a tool from a rectangular bar, which can be ground manually. Height and width parameters determine the cross-section. The remaining parameters describe the cutting edge position. I calculate the red tool and display it.

- Spanish translation
That's a good idea. If you provide me with the texts, I will be very happy to include them in the program.

- Inside turning
If I have to turn an inner profile, I simply turn the turning tool by 180°. Then you can use the same program as for external turning. See attached pic

- to carbide inserts
I could imagine working with two things.
- The shaft is loaded as a simple STL object.
- The insert is determined by parameters like the 'parameter tool'. (Which parameters do we need for that ? )

Thank you very much for your answers.

It seems to me that I have not the last version of GG.
I cannot see those options for the lathe configuration in the settings menu,

I will be back on the carbide inserts soon.

Best regards,
Leonardo

You can always download my current beta version at https://bit.ly/2xCD7Nd_GrblGru_Beta
download. But you don't need the new settings parameters. They are only for the special machine.

Thank you again.
I download the beta version but I still have the same problems:
- I cannot see the checking boxes in the 2D menus nor select any of them.
- I cannot open the "NC (G-Code) Creator" menu.
- I cannot see the menu on the right of the screen that I saw in some of your videos.

When i import a DXF file, the software generates the 3D model rotating the curve. Then I can see the 3D representation and also the curves present in the DXF file but placed with an offset between them... (???)

Anyway, I will continuing trying options.

Regarding the CARBIDE INSERTS.
There are a zillion of inserts! Also they are quite expensive so it is impossible for a hobbyist or a small company to have many of them.
I chose five of them but specially one that is very small so it is not so expensive. Because of this I always look for tool holders that let me do different operations but all of them use the same insert. I am talking about the little CCMT 0602x0x.

I really love the inserts. They are indexable, what means that you can rotate the insert to a new position and have a new and sharp tool without moving anything. You can stop the machine, rotate the insert or even change it by a new one, and continue with the job as nothing happened. There are indexabe inserts that have 2, 3, 4, or 5 positions. There are also no indexable inserts and reversible inserts. Once that cut CW and others that cut CCW... and so on. As you can imagine this is a very wide and deep sub-world!

AS for the parameters, I would say that we may only need the external contour (the first letter, "C" in this case) and the radius of the working tip of the insert.

I am attaching some images for you down here that will explain some concepts clearly.

Have a nice weekend!

I am attaching a couple more images of another type of insert that I use.

Also, folowing this link you will find a LOT of info... and this is only one brand! http://www.iscar.com/eCatalog/Applications.aspx?mapp=IS

I am appreciative that you would set aside such a great amount of opportunity to enable me to out. With the data you gave, I ought to probably make the links.

@Leonardo
I'd like to know why the program doesn't work for you. So here are the necessary steps again. Please tell me at which step it doesn't work.

1. loading a DXF file e.g. ChessPawn.dxf
2. input of the 'start diameter' in the 3D view. => 35mm
3. press the 'Origin' button to accept the start diameter
4. in 2D view -> press right mouse button in TreeControl on branch 'Drawings'
5. in the opened context menu select 'Create jobs for all layers' and then 'rough + finish'
6. The window for entering the process values should open.

For the CARBIDE INSERTS please give me some more time. I will prepare something there.

Release notes V3.35

On my Dropbox a new version is available for download. bit.ly/2xF1KJ8_GrblGru_Release

The pocket milling functions were reworked and completed with a StepOver input. Also the production of chamfers is now possible with V-Cutter as well as limited with normal EndMill.
I will try to make a video about this soon.

I am especially pleased about the provision of Spanish texts by user DANTRON. He also contributed 2 very nice 3D-models of his self-constructed milling machines. Thanks again for that. :)

Have fun with GrblGru

Hi GG, thank you very much for the directions. I followed your instructions and did the example perfectly.
I am still having problems with my own part. I will investigate more...

Regarding the Carbide Inserts, please, do not develop this just for me. I know that you are making a great effort although you say that it is a hobby and you like it very much.
The maths to work with the carbide insert will be not easy, you must to thing in compensating the insert tips radius at the time of moving the tool. This means that you will need to develop a look-ahead routine... really a huge amount of work!

As for the new Spanish translation, I downloaded your last release to see how it looks. Although it is way much better than the previous one, there still are some things to review because there are many text without translation. I also realize entering in debug mode to see the variables, that you have not provided access to some text that will need translation to have not a merge of languages. I am attaching a screen shot in which I marked those areas.

There are also some little mistakes derived, I think, from the English because they are not exactly named.
Most confusions are in the Carriage what is the bigger one that holds all the other parts. What is currently called "holder" in the software actually is the "Tool Post".
Here in Argentina we call "Carro" to the "Carriage", "Charriot" (what is 'little carriage' in french) to the "Compound Slide or Compound Rest" and "Torre" to the "Tool Post". I've stolen an image from Internet that shows the proper English names of a lathe parts.

Hope this helps to improve even more the translations.
