Hi
I have had exactly the same issue and it isnt the board from my experience. The following would happen
- Start a job and it would suddenly freeze for no apparent reason at no specific time on any job. Sometimes it could complete a job.
- The counter on the progress bar would still be counting but the bar not moving.
- Unable to home or go to origin or move the laser head at all.
- The only way to get things working again was to disconnect the control board power and usb to computer and start again.
I tried 2 laptops and 1 desktop computers.
-
The 1st laptop had Windows 8.1 and is 9 years old. I reinstalled the OS and only had Lightburn running on it. I ensured that all power saving features such as USB power sleep mode and screen savers were disabled and switched off wi-fi. I also disabled any non essential processes that run in the background such as antivirus etc. Unfortunately this didnt resolve the issue
-
Tried a PC running windows 10 again an old machine (10 years ) and I duplicated the process as on the laptop above still no luck.
-
The second laptop worked running windows 10 and now 11. This is a much newer machine only two years old and I didnt have to do the configuration changes as I did to the other two machines.Its not a high spec model.
What I did find is if your running the Lightburn files across a network or off a local usb the drop out did happen even off the windows 11 machine.
I would try some of the configuration setting I did. Hope this helps I know how frustrating it is
