Have fun with GrblGru

Hi, GrblGru!
Thanks for new version!
Can I distribute my machine model to other GrblGru users, using the .tco file from the folder ..\ProgramData\GrblGru\Models?
Regards, Alex.

Yes, of course!!! I would be happy if you would do that. :)

I must apologize to you. I wanted to add your great model to the program much earlier. I wanted to simplify it a bit before. And unfortunately I didn't have time for that.
Thank you very much for your support.

I want to apologize for not reporting on the implementation of your "Posts: 207 Joined: Sat Nov 01, 2014 5:44 pm" instruction. Unfortunately I did not succeed- shame on me.
That are the instructions and their results:
1. start the homing process
Done.
2. press the macro button "parameters" and note the positions.
(see screenshot #1)
Probably the grbl-controller after performing the "homing cycle" resets the machine coordinates
3. touch your part as described with the knobs.
Done.
4. press the macro button "parameters" and note the positions.
(see screenshot #2)
Nothing changed
It is explainable - the machine does not have encoders and the grbl controller did not notice the change in coordinates.
5. press the "Origin" button.
Done.
But still no changes
6. press the macro button "parameters" and note the positions.
(see screenshot #3)
7. start the homing process
Done.
8. press the macro button "parameters" and note the positions.
(see screenshot #4)
Perhaps that problem (with manual moving with the knobs) has no solution.
Therefore, I will focus on finding the precision remote control, so the GRBL controller will always know the current position of the tool after performing the “homing cycle”.

About model of machine CNC1310 for the GrblGru program.
I'm not sure that you should include my model in the release of new versions of the GrblGru program. It has several times larger size than other models. It would be nice to have a public repository (like as GitHub) for program users to download the models they need. However, I simplified the model (eliminated spiral surfaces) that improved the situation twice. But still .tco file has a 2.9MB. Here is the new model: https://www.dropbox.com/s/r36scg7wagd6n ... u.zip?dl=0

I've simplified your model once again. Now it's a compromise between good performance and good representation.
It's not so nice anymore, but I hope you still like it and you can work with it. :)

On my Dropbox you can find under https://bit.ly/2xCD7Nd_GrblGru_Beta the new version V3.34.1 containing CNC1310.
Please let me know if something is not ok.

You have to answer the question during the installation with 'Yes' to overwrite the old files. Make a backup copy first.

I expected different results for the positions of the axes. Give me a little time. I have to think about it again.

Wow! Thank you very much!
It's amazing!
But I have a question about the homing position.
It’s written in the GRBL manual: "By default, Grbl's homing cycle moves the Z-axis positive first to clear the workspace and then moves both the X and Y-axes at the same time in the positive direction. ”
Positive direction of the X axis - to the right.
Positive direction of the Y axis - spindle forward (table - backward).
Please watch the short video (36 sec) to understand what I mean :)
Also, after the origin command and loading G-code, the trajectory is drawn below the table level.

I'm not sure I understand your question right.

The program cannot know where you mounted your limit switches. Therefore you can enter the position of your machine after the homing in the machine manager.
The attached picture below e.g. shows the position from your video with Yr = 90mm.

Please also note. If you press the 'Origin' key, the Z-axis is positioned so that the tip of the tool touches the top of your workpiece. The inputs 'V-Offset' and 'Thickness' from the group box 'Stock' are taken into account. In reality this corresponds to the situation when you touch your workpiece with the tool.

I hope this helps you. Please let me know if I didn't understand you correctly.
