I have a question. Is it possible to change the coordinate system of the lathe from "X-Y" to "X-Z" in GrblGru? My lathe understands only two coordinates "X-Z". And the coordinate "Z" is the axis of rotation of the spindle while "X" is the feed of the tool.

Can anyone advise why I can't run the simulator on following file:
https://drive.google.com/file/d/1ArQ...ew?usp=sharing
Using GrblGru V3.28.1
I'm getting a lot of unhandled exceptions.

[GrblGru]

@gryzel
Right now, I'm in the process of changing the lathe coordinate system.
Give me a little more time, please. I hope to finish it this week.

@swisscheese
I read your file and for me everything looks very good. The simulation is running and I don't get any error messages either.
It would be very helpful for me if you would open the two controller windows and run the simulation in single step mode. (Toolbar button "Single")
Can you please send me screenshots of the error messages and the display in the controller window ? So I can see which command causes an error.

Please also take a screenshot of your self-defined tool "187 EM". What is the diameter of the cutter?
Do you only have this problems with this file, or do you have the errors with every file?

[swisscheese]

187 tool: Milling, Endmill, 6,35, 0, 10, 2, 2, Yes

I never got anything to work - just learning it.

As soon as I open the project file I get:

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

@swisscheese

That's strange.
Can you please select another milling cutter in all 3 jobs for testing (e.g. "end mill 3.175")

If this doesn't work either, please load the DXF example "MotorPlate.dxf" and create a simple job (e.g. "Slot Plywood") for the layer "center milling".
Make sure that you have selected "Controller" = "Simulation". Press the "Origin" button.
Select "High speed simulation" and press the green start button.
Is the simulation now running without errors?

[swisscheese]

With your suggestion I found the problem. I had my tool setup wrong. I had number of flutes at 0 and width at 2 - should be 2 flutes and 0 width. Suggest to improve defensive code / error reporting.

[swisscheese]

Now I have another problem. Grbl Panel stops in the middle of the GrblGru program for no reason. I found that if I delete exclamation marks (!) in comments that GrblGru generates it resolves the problem but doing that is cumbersome. Please advise.

Also, please allow to toggle items on and off during multiple selection - this is standard UI. Otherwise it is very difficult.

[GrblGru]

@gryzel
I've uploaded a new beta version V3.28.6. bit.ly/2xCD7Nd_GrblGru_Beta
This contains the new standardized XZ coordinate system for the lathe.
If you want, you can try it now.
I'll try to make some documentation, but this will take a time.
Please note that you must first enter the diameter on which you start in the new entry "Start diameter".
Then after loading a DXF file you can add a job for the toolpath in you drawing.
Everything now works in exactly the same way as when milling.

@swisscheese
Thank you for your feedback. Even if it doesn't run 100% yet, I'm glad that the first error was found.
Sorry, can you please explain again what you mean by "toggle items on and off during multiple selection". I don't understand.
And can you send the file that causes the error with the "!". I'm sure we'll find that, too.

Hi GrblGru,

Saw your posts that you have been working on the X/Z lathe system and uploaded a beta version.

That's really cool news and I'll try to play with it in the next few days to run my son's Unimat Lathe.

Thanks for all your hard work and sharing your talents with all of us !

[swisscheese]

@GrblGru
Go into Windows file manager; hold down the Ctrl key; click on various files - some more than once. That is how mutiple selection is supposed to work.

Also, why is the U notch in the upper right part not fully machined in this file:
https://drive.google.com/file/d/1FqD...ew?usp=sharing

[gryzel]

@GrblGru
Thank you for beta. Still buggy, but usable. Hope you polish your program. If you need bug reports I will provide you with some. Let me know.

[GrblGru]

@swisscheese

Thank you for your explanation on the subject of 'multiple selection'.
I assume you are talking about selecting a toolpath from the drawings list. You're right. It's a standard interface, but it's work, that has to be done.
I'll do my best. In the meantime I would like to point out the possibility to select the paths directly in the graphic window. I think this is more comfortable.
You can select one or more paths with a window (left mouse button) or one path with ALT + left mouse button.
A click with the right mouse button opens a context menu with which you can also hide or delete paths. Here you can also create a job directly.

I checked your file and can't find any errors.
Also the PreView looks good to me. See attached pics. Can you please describe once again what's not okay ?



@gryzel

Yes, of course. Bug reports are welcome.

[swisscheese]

Thanks - now I see multiple selection on the drawing works correctly - that will work for me.
I figured out the toolpath problem - I had my 3/16 EM with diam 6.35mm which is 1/4"! My bad.
My biggest remaining gripe is having to manually remove "!" characters after every g-code export.

[GrblGru]

That '!' is the stop command for Grbl, but it is written in a comment and "Grbl Panel" is not allowed to stop there.
However. I have uploaded to you a new beta version V3.28.9. I found one place in it and removed the '!'.
If you find a text with '!' at other places, you can find in the directory C:\ProgramData\GrblGru your language file
where you can change the text. (For English text = Language_English.txt)

Finally, the note that you can also use GrblGru to transfer the GCode.
All you have to do is select your controller and your Com port in the "Configuration" group box and press the Start button.
You can then check the transmission in the two controller windows. See attached pic.
Another advantage is that GrblGru then uses Grbl's feedback to animate the 3D model of your machine. So the 3D model moves synchronously to your 'real' machine.

If you use "Grbl Panel" because it has a function that GrblGru does not have, please let me know.

[swisscheese]

I found some "!" in the language file but mostly in comments - did not seem like removing them would help. Is there a particular line?
Where do I get V3.28.9 ?
As for using GrblGru intead of GrblPanel, the later has jog increment settings, GRBL settings, special goto positions, pause, resume, manual G commands (MDI) - that's what I use.

[GrblGru]

You can always find the current beta version at bit.ly/2xCD7Nd_GrblGru_Beta.
and the last released Version at bit.ly/2xF1KJ8_GrblGru_Release

If you still have problems with the '!' please send me the GCode file so I can see what's going on.

I hope I don't talk like a salesman, but:

- jog mode ist available, also with remote control
https://youtu.be/HSsUbzgWuzo

- GRBL settings can edit in the controller window

- Special goto positions and functions can be realised with simple macros
(The macro toolbar must be enabled on the settings page)
https://youtu.be/5UIVro7R7AU


But GrblPanel is certainly a very good program and I prefer to use programs I know well.

[The_Dream_shed]

Any hope of adding the g20/g21 (Inch/Metric) functionality? That seems to really be the only thing missing here!

[swisscheese]

@GrblGru

Decided to try using GrblGru instead of GrblPanel but jogging gives error "Grbl error 15 ... Jog target exceeds machine travel".

[GrblGru]

@The_Dream_shed
Thanks. Of course I have it on my todo list.
But right now, I just can't find the time. But I promise I won't forget it.


@swisscheese
It works for me without errors and I have not yet received any negative feedback from other users.
Error 15 is an error message from GRBL. Are you sure you have GRBL version V1.1 ?
Does the error appear every time the button is pressed or only sometimes?

I'll make you a video tomorrow to show how it should work.

[GrblGru]

Release notes V3.29

A new version V3.29 is available for free download on my dropbox. -> bit.ly/2xF1KJ8_GrblGru_Release
Most of the changes concern the lathe operation. The coordinate system has been adapted to the standardized XZ system.
Creating jobs now works in the same way as when milling. Now also templates for turning chamfers and radii have been added.
Suggestions for other useful templates are welcome.

When milling, internal geometry data can now also be exported as SVG and G-Code can be imported as data.
I also started to include OpenSCAD.

Have fun with GrblGru
