I get random “Connection Lost” error during engraving, and after several days of the tests, I assume it is Lightburn issue. So will be glad for any help.
I have Smoothieware CNC on MKS Sbase with Endurance Laser on cheap chineese frame (I used GRBL and Arduino based controller before). It works under old laptop control on latest Windows 10.
So during engraving I got Connection Lost error. I thought it may be because of compressor for air assist or power relay work, but I excluded this, it appear without any connection to equipment actions. Also, the board stay active, it don’t halt or reboot, it saves previous laser head position and can be controlled after this error without any issues.
Yesterday I did more tests and now I am sure, that something wrong with LB, because:
I did successful 3 hours engraving from SD card, without connection to the PC (I have LCD to run commands)
I did successful 3 hours engraving from GCODE file (the same gcode) in LB, with USB connection
and today I run it again, directly from LB, and got an error after 12 minutes. Sometimes I get the error after 3 minutes and sometimes after 45 minutes (or no error at all but the chance is near 25% for this, as I had 4 failed jobs per 1 successful).
Right now I am waiting for another test, all the same, just to be sure, that it will repeat again.
So I will be glad for any ideas.
