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

@Daggersuk
I am not aware that GG does not run under Win32. If I understand you correctly, the program can be started without errors.
Can you explain exactly what happens when you press the button? Some screenshots would be very helpful.


@jpascher
Which GRBL version do you use ?
There are many great features in V1.1 and the communication via USB is different than in V0.9.
That's why GrblGru no longer supports GRBL V0.9. It needs V1.1
If you are already using V1.1, it looks like an error in my program.
Can you send me a sample file so I can see exactly what it is ?
Which controller do you use ?

[Daggersuk]

Thanks for the reply.I am using a MKS DLC V1.0 controller board, grbl V1.1 I am away from workshop until Thursday but the details that I can recall are as follows:-Program loads and starts without errors. I can load dxf,stl and gcodes without errors. I have loaded a sample gcode nc file and run on both software simulation and the actual machine. I can create a STL file from a dxf but the create N.C button remains greyed out. The only other problem I have had so far found is that the Z axis is reversed. I have also created a new machine and run simulations using this without problems.

Thanks for reply!
i use V1.1 on NANO
attached stimmstock.nc -renamed to stimmstock.txt
Within Fusion360 a post processor is installed form: https://github.com/Strooom/GRBL-Post-Processor/wiki

@Daggersuk
What you're saying doesn't sound bad to me.
Because I don't have a decent manual yet, I assume there is a misunderstanding how to use the NC-Creator.
That's why I made you a little video showing you how it should work.

Please check it out, and contact me if it doesn't work for you

@jpascher
I hope I could fixed the bug and it will work for you now. From my dropbox https://goo.gl/7BGkkO you can download a new beta version V3.26.12
The error only occurred under certain conditions with larger files and has therefore not yet been detected. Thank you for your feedback.
May I ask what you need the G-code for? The simulation of the path looks, let's say, "very strange".

@vicstransam
I finally managed to check the diogonal keys to see if they leave the range of travel.

Hi
The flow as shown in your video has been working fine on my system, the only problem is that my Z axis on my machine is reversed. But the work flow I could not get to work is the DXF to STL to N.C. I can create a STL using the “create STL button” but the “create N.C.” green arrowed button seems not to function on my setup. Thanks for all your efforts.

@Daggersuk

I'm not sure I understand you correctly. But in case you want to have the G-code directly from the STL object, I have to disappoint you.
I can't calculate that at the moment. There is only one slicer in GrblGru, with which you can cut the STl into slices, from which you can calculate the 2D G-Code.
Sorry, my goal for the future is to be able to calculate G-code for a 5-axis machine. But I'm not ready yet.

For the error with the Z-axis, please take a look at the required coordinate system when creating the 3D model.

It works!
.
I have a question about G28 homing code. The simulator seems to think that G28 is to return to part zero instead of machine home reference point.
Also, is there a MDI function available? I was thinking I could type directly into the gcode window and it act as manual data input.
Forgive me if this has been covered in a video as I haven't yet seen them all.

Thanks again for your substantial contribution to hobby CNC.

@vicstransam
I put a short video on my dropbox. It shows how to access GRBL directly from the command line.

Very nice! Thank you!

[sacramento]

First of all thank you for your excellent software and congratulations for it.
I plan to use it with my lathe wich works with Mach 3. As someone said before axes in your software are not standard but that is not an issue as we can edit g code and easely change it.

I have one doubt. I have some parts that are turned on the outside (with that I have no problem) and on the inside, and that's where I don't know how to do it.
Cab you please explain if that is possible and how to di it.

Thanks

@Sacramento

Unfortunately I don't have an extra function for turning inside.
Until now I have always turned the tool by 180°.
See pic. Top=normal position for inside turning, bottom+right= tool 180° turned
This allows me to use the same routine as for turning outsides.

For small special contours I like to use the macro bar on the right side of the screen.
This allows you to quickly write a small Gcode routine.

If that doesn't help you, please tell me exactly what you want to do.
I will then try to find a solution.

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.

Have fun with GrblGru

has anyone gotten GrblGru to run on linux using wine ?

[junior2016]

I got GrblGru running on Linux Mint with the following procedure:

• start up PlayOnLinux (POL)
• start the wizards to Install an Unsupported Application
• use wine version 3.7
• install corefonts
• install the dotnet45 library (this took some time and I a lot of fiddling but is the key step as GrblGru does not run on the default mono dot net libraries)
• download and extract the GrblGru exe and select it as the app to install on POL
• create the shortcuts and run

[GrblGru]

That's fantastic !!! I have had some requests from Linus users so far. But no one's ever done it before. Congratulations!

[junior2016]

How do you specify the stepover for pocketing operations ?

[GrblGru]

@Junior2016

Sorry about my late response. I was on vacation last week.

Until now I have no separate input for stepover. A constant stepover of 0.5 mm is used.
But a new input with a percentage of the tool diameter would be a good idea for the next version.

I am very interested in your Linux version of GrblGru. Please let me know if there's anything else I can do.

Hi

It will be a good improvement if one can create latthe tools as I could find only 2 tools and could not adapt them.

Sacramento

You can create your own lathe tools.
Please watch my YouTube video. "GrblGru: Unimat lathe turning dxf files"
Chapter 2: "Available lathe tools" describes how it works.

Thanks for your reply. When do you expect to have carbide inserts usable?
NeverthelessI could not find them as shown in your video. You say tey are on to do list but my list is empty.

And on database Tool I only can find ISO cnmg120408.

Can you explain how to proceed

Thanks
