Most likely, the timing of this issue beginning after you updated LightBurn is purely coincidental.
Do you see any error messages in your Console window when your laser stops, or a ‘start up’ message that tells you your laser’s firmware version and some other information? If so, please copy and paste the output you’re seeing here.
Your laser may be losing connection due to a loose USB connection, a USB port sleeping, static discharge causing the controller to reset, or insufficient power supply leading to a brown out condition.
Here are some resources to help you troubleshoot these issues:
I also had to upgrade the firmware on my Sculpfun after the last update.
Probably found the source of the problem. When USB is connected to Sculpfun, but the power switch is OFF, the computer still communicates with Sculpfun PCB. Execute the program without moving motors or activating the laser. What is interesting also at this time comes strange symbols in the Lightburn console(
<Idle|MPos:-23.388,-1�r���b�r����M�0,0|WCO).Was trying to make earth bonding, soldered extra mass from the USB to the laser frame, and changed the USB cable. The problem was stopping for some time to reappear again. Probably the key problem is temperature. When is hot in the room all works ok, when the temperature is low -problems start. Today morning problems appear from begin, warmed up the main PCB for a few seconds with the hairdryer and all start to work perfectly. Waited 15 minutes and problems appear again. The temperature in the room is now around 12 Celsisus deg. Again warmed to around 20 Celsius deg and again working OK.
