GrblGru = Free 3D-Simulation for ShapeOko2

[Alexmoon]

@Alexmoon
Your 3D model must have a probe (green probe), which you have to save under t++.stl.

Hi, GrblGru!
I am sure that 99% of users of three-dimensional cnc machine, use a spindle with a milling cutter or engraver as a probe. For example, for accurate measurement of Z-origin. Especially PCB-developers, like me
In addition, modern probes have the form like as cutters and are installed in the spindle cartridge
So there is no need to display a separate probe on the machine model.
Could I ask to include the following cases to the backlog of my favorite program GrbleGru? (maybe far future)
1. Separate origin setting for horizontal plane and Z-axis (after measuring with probe)
2. Correction of a loaded G-code data with data from a height map, obtained using the scan function.
The fact is that milling of PCB is performed at a depth around 0.05mm. Because of this, the unevenness of the board is very critical for quality.
Some programs have such functions
Thanks!
Regards, Alex.

Hi Alexmoon,

Could you tell me how type of spindle motor are you using, please?

Also, what is the measure of the collar in which you are attaching the motor?

Thank you!

Hi, Leonardo!
I am using Windward S4225-B24 spindle (24000 rpm)
But my choise was due to the features of my machine.
The collar pictured on the photo https://cnc1310.ru/Picture/GetPicture/132,
has a diameter of 42mm and a height of 30 mm.
Are you a cnc1310 machine owner?
If you are - I can send you a solid model.
Otherwise you will not need it

Hi again Alex!
No, I am not a cnc1310 owner.

I was curious to know if you are using a Europe standard collar (43 mm) or any other. Makita, Bosch, Isel, Kress etc. use 43 mm collar but they are not suitable for PWM control.

Thank you for your answer and offer.

Alexmoon,
your suggestion sounds very interesting. Most of the required functions are already included in the current GrblGru version.
But the projection of a GCode program on the height map I still have to create.
It would be helpful if you could provide me with a GCode example file.

Example of G-code for PSB:

Let me know what examples you need.

Thanks for the fast delivery

Release V3.37

Most of the changes in the new version concern the lathe mode again.
Because Carbide inserts are used more and more often on hobby lathes, I have now added this type of tool to my program.
In addition, I have revised the complete turning handling once again and I hope that the operation has now become even easier.

Many thanks to my friend Leonardo, who helped me a lot with his suggestions and good ideas on this topic.

Have fun with GrblGru

You are very welcome GrblGru!

Congratulations on the new release and the helpful video!

All the best!
Leonardo.

Release notes V3.38

In my new program version V3.38 I once again worked with the function G38.2 for milling.
This good and at the same time easy to use function makes it possible to scan uneven surfaces, e.g. to engrave them afterwards.
The same applies to the production of PCBs, where any unevenness must be compensated.
GrblGru also offers the possibility to scan STL objects in simulation mode.

Download, as usual from my website at http://GrblGru.com
