Hi,
nice work! Axis move smooth.

Thanks

Not yet tested thoroughly!
In addition, sometimes for some unknown reason the response from the controller to the request is delayed for a noticeable time (up to 1-2 seconds). This is rare and only affects the display of the current position. It does not affect to the code execution.
Therefore, improvements are required.

Several times had gcode terminated before end, but now seems its ok.

Several times had gcode execution before end

What do you mean?

[klembaris]

Before finished cut, gcode was terminated.

[robomechs]

could you send G-code example and GRBL settings?

[klembaris]

Before i used another control soft, and maybe its was control software problem.

Ok, thanks! Please, report me if the error will be repeated.

[klembaris]

Sure!

Hello,
@yaroslavVl
thank you for this work on the 4th axis.

@klembaris
thank for the file 'aspkr.nc'.
Here is a representation of the path of the tool and the axis of rotation 'A' : with 'Mega2560' and 'grblQ'

I will try to do it with the version 'Stm32F103' ...

Have a good day

Hey guys, might be a stupid question but I can't find the branch or any configuration for the 4th and 5th axis in 7e3308b. Where is the code for the 4th and 5th axis?

Thanks
