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

[jcorona]

@jcorona - One suggestion, this is it, here:
Nesting
--> Just a suggestion!

Exactly!, this is the concept, though I'm thinking a simpler version for easy implementation sake . Thanks for the suggestion!

Please have a look at the new beta version V4.0.1 on my website. With this it should be possible to create the desired duplicates.
Let me know if something does not work

Hello. Thank you so much for your project. I'm trying to join you. Finishing the machine with FoamCutter but with an additional y-axis between the towers. I have questions about how to control the axes. Sometimes I need to use the machine as a simple foam cutter with y = z and x = u axes. sometimes the axes must move separately for complex cuts. In milling mode, the axes should only move together so as not to break the y portal. Each axis has its own engine and its own limit switch. how to organize calibration? In the Marlin firmware, this possibility is provided, and in GBRL I found only a mention of the possibility of cloning axes, but I could not do it.
In the early posts of the forum there is a mention of a video on how to set your model of the machine model, but the links are no longer relevant.
Thanks again for your hard work.

Unfortunately, I have not yet understood exactly how your machine works. Can you provide some pictures so that I can better understand what exactly you want to do?
If you have a 3D model of your machine, you can integrate it into GrblGru. The manual on my website describes how to do this. I am also happy to help you with this.

On lathe mode Can we change the origin x0 y0 point in the middle of the cylinder (part) when origin point is outside the part it brings more mistakes after changng tool for CNC which have manual tool changer.Can you do that ? And your program needs to support .STEP file too its most common 3d share for jobs i know you have made it for hobby but you are going perfect in this
Thanks!

Sorry for my fault in the post processor i have seen the mach3 coordinate system but it doesnt work with the full diameter like this :

Hello, here's a simplified model of my machine. The coordinate axes of my program do not match, but I adjusted them to fit your program. I import STL files into a new machine and first of all they do not match with each other and do not move as I need. When I launch FoamCutter, I can't create even a simple program, let alone a 4-axis one. I create a macro with a code and the program moves only along 3 axes, U = 0.

@Yvzylmz
You can always select only one of the two options. You must not select both together.
As a result you get a file with the changed values, which you must then load on your controller.

Sorry, I will not be able to load STEP files. That is much too complicated.
You would have to buy a software library, and I don't want that.




@botowbot
Thanks for the files. I will check it. Please give me time for it.

Great!, will try and let you know!

It seems to be working fine with one exception: entry point is not getting copied.

Hello GrblGru
From version 4.0.0 to current version 4.1.0

Postprocessor does not work!
Extras ---> Postprocessor

Thanks for every help. Now in the version 4.0.2 there is a fault of importing dxf files it says database error ? and closing the program ...

You have made the X diameter double clearly in the post processor can you change its origin in the middle of the part then double 2 things in 1 post processor

[Armando]

I forgot to mention that in my configuration is.
Machine ---> Cobra
Only the Postprocessor works.
In version 3.50.9 and 3.50.10

Hi everyone. I got a problem when importing a DXF file for 2D processing, I only display a part of the vectors. The bil file was created in the Rinoceros program. The files themselves are in the attachment.

[GrblGru]

@jcorona
Please download new version V4.1.1

@Armando
Please download new version V4.1.1

@Yvzylmz
- Can you please provide me the file that causes the error ?
- Can you explain the problem with the postprocessor again in detail. I have not yet understood what you need. Screenshot, pictures etc would be very helpful.

@mordhard
I'm sorry but the file uses splines that I can't handle yet. Splines are quite complex and there are a lot of variants.
Of course not a real solution, but maybe a workaround:
With many programs you can set how the export as DXF should be done.
Often there is the option "Save curves and surfaces as polylines".
It may also be that there is an extra command to change the type.

Good day. Thanks to the emergence of new links to other forums, while studying them, I managed to correctly integrate the milling part of my machine into the program. It turned out that such a mechanic already exists, called Lowrider. As far as I understand, to work in the mechanics of the foamcuter I will have to create a different kinematics. The question is that it is not working properly. However, the eggbot kinematics also work incorrectly.
Is it possible to get a link to a program of an old version, something like 3.20.7 or the latest version where eggbot is running. I understand that the problem is related to a huge number of very necessary program fixes. Somewhere in the comments under the video, I saw perhaps your entry that this kinematics is no longer interesting and therefore is no longer supported. I really want to be wrong. Because of your program and thanks to it, I finally forced myself to make such a machine.
If I understood everything correctly, then perhaps there is a version of the program where the foamcutter exactly works.
For storage space, I recommend using the https://www.dubox.com/ server there is a very large free space. But you have to try a server with limitations.
My main question remains how to switch between kinematics with the least difficulty. You can reflash the arduino every time, it's even worse to re-solder it manually. The most comfortable option is to add a button to the "remove y-axis" configuration of the machine. I don’t know how difficult it is to implement.

@botowbot

I can understand your wish to control both applications (Milling machine and FoamCutter) with one program if possible.
However, this is very difficult to realize because you have to make many different switches in the controller as well as in the GrblGru.

My suggestion would therefore be a simple hardware solution with 2 controllers.
For the milling operation (3 axes) an Arduino UNO for less than 10 dollars is enough. For the FoamCutter ( 4 axes) you take the controller you have now.
Depending on what you want to do, plug the USB cable into one or the other processor.
Do the same with the pulse and direction signals. (if possible over one connector)

In the attachment you find the files "botowbot.tco" and "botowFoamCutter.tco", which you can copy into the directory "C:\ProgramData\GrblGru\Models".
The file "Machine.dat" must be copied into the directory "C:\ProgramData\GrblGru".
I have also added the corresponding STL files just for your information.

With this, both models should be working. With the FoamCutter the heating wire is not yet positioned correctly. I will do that in the next program version.
Then I will integrate both models permanently in GrblGru.

Finally, a note about the EggBot. I developed the project some time ago. But there was no interest from users in it.
The kinematics are quite complex and so at some point I decided not to make any more changes to it.
I have a lot of work to do at the moment, but when I find some time I will have another look at it.

Has the 'Smart Saw' function been removed from the program? It is not available in the Extras menu in V4.1.0.

[Yvzylmz]

@GrblGru You have coded X as diameter choice on the postprocessor thanks for it. But Can you change this selection's origin like mach 3 coordinate system? Because its very hard to set Zero point to the outside of the steel. Origin 0 0 point must be the middle of the steel

[Armando]

@GrblGru
I attached a GRU project file, to be analyzed and studied.
My config is Cobra.
This example it detects the mesh but "does not pierce the mesh".

If I apply "Job STL -> 3D Finishing Waterline17mm" it punctures the mesh.
