Either Candle 2 or Grbl board not response or not stable feedrate high said > 2500 about candle2 HOT 9 CLOSED

Hello,
which version of grbl are you using?
Can you post your $$ settings?
Can you attach a gcode file where this behaviour occurs?

Hi,

I had tested with https://github.com/thomast777 - F46 verion,
if not mistaken your version of Grbl-Advanced also having the
same problem with stm32F407ZGt.

The attach file's feedrate I had modified to F5000 for testing.
Buddha.zip
This is one of them sample files.

Here my setting tested on yesterday.

ok

from candle2.

just noticed always stop at line 1375 and ERROR: Axis command conflict.

from candle2.

I will look into this

Any progress ?

from candle2.

Kind of... I did several tests on my ubuntu machine. Had no problems at all, everything ran perfectly.
But you should reduce your decimal precision. 3 digits after the point are enough. It will increase performance. By now grbl spends almost all of its time parsing the gcode, since it contains too much digits.

from candle2.

Understand, It could be OS issue also.

Btw im using I7 HQ 4700 2.4Ghz 8G, NVidia 750M, Win7 Ultimate, it shld be enough process
to handle the Gcode parser.

I noticed the app spends much of time handle the update the GUI, like updating the status and control button. Not sure how Qt handle the GUI, I do had bad experience with C# handle multi-threaded GUI.
