And specially for Xav-83 just make a new plugin for Grbl card...

Thanks

Hi Xav-83,

Thank for the info...
I understand for $$, but for $# what is the command for changing a parameter like [G58:0.000,0.000,0.000]...
I need to know the syntax...

edit: can you confirm that you can upload file with the new plugin... I am not really sure...

[Xav-83]

Hi,
for change parameter of $# it seems to me that it is with the G10 command.
I never had occasion to use it

G10 Programmable data input --> Modifies the value of work coordinate and tool offsets.

Wiki grbl

G54-G59 work coordinates can be changed via the G10 L2 Px or G10 L20 Px command defined by the NIST gcode standard and the EMC2 (linuxcnc.org) standard. G28/G30 pre-defined positions can be changed via the G28.1 and the G30.1 commands, respectively.

When $# is called, Grbl will respond with the stored offsets from machine coordinates for each system as follows. TLO denotes tool length offset, and PRB denotes the coordinates of the last probing cycle.

When I upload a file, I can't see the toolpath in freecad. I can not confirm to you whether it is the correct file.
However,
1 I charge one of my files.
2  I made a "Home"
3  I put my tool in origin parts
4  G91 X0 Y0 Z0;
5  I run machining
6  the truck from too far out of range of the machine.

Hi,

G54-G59 work coordinates can be changed via the G10 L2 Px or G10 L20 Px command

Ok i need to send GCode command... and I need to learn because I am a beginner...
But It's a good way to learn ...

When I upload a file, I can't see the toolpath in freecad

I have not integrated the "toolpath" in the Grbl Plugin because I don't know the format of the positions received from Grbl while uploading...
Whith TinyG2 it look like: "posx:12.086,posy:0.453,posz:0.000,feed:300.00,vel:300.00"
But IMO, if we want to integrate this feature, need some help because what I do is just crap (but just to see that it was possible ...)
I hope someone will hear us...

I can not confirm to you whether it is the correct file.

Ok, I just remake file upload. Now I hope it's more reliable...
And have integrated the $$ command... You can test and say...

As per my experience with these things if you are going to attempt a Controller Workbench for 3/4 axis control, you must take the interface along the lines of GRBL Controller.
Also this kind of interface within a FreeCAD module and able to work hand in hand with Path, would be a great well rounded package Path / Controller.
It might have to remain separate from FreeCAD due to the license, (GPL3), though I can never keep those things straight, what's compatible, what is not.

Hi HughTufano
Your first post, welcome to FreeCAD.

due to the license, (GPL3),

yes, it complicates matters.

Hi HughTufano,

Welcome to FreeCAD Forum...

if you are going to attempt a Controller Workbench for 3/4 axis control, you must take the interface along the lines of GRBL Controller

it would be better to start from scratch, if we want to manage other card than Grbl like TinyG2...
it would be good to have a generic core and make a plugin for each card (Grbl, TinyG2...)

I have to work on that, any help is welcome

Hi,

I have just installed FreeCad and I would like to control my Arduino using this amazing program. However, I currently have an Arduino Due, and i'm having this error.

Running the Python command 'Usb_Start' failed:

Thank you
