I have a Creality Laser Falcon 10W laser and Lightburn v1.4.00 running on Windows 10 Pro 64-bit with all of the latest updates.
After a home, frequently LB just sits there like the first screenshot below until I restart the program, at which time I see the message in the second screenshot. Occasionally just restarting the program doesn’t fix it until I reboot the PC. Even though the status returns to “ready”, LB is not able to communicate with the laser at all until I reboot. When this is the case, I see this message in the console, repeated over 100 times:
Waiting for connection…
o: gpio_isr_handler_remove(480): GPIO isr service is not install, call gpio_install_isr_service() firste[0m
e[0;31mE (25565096), call gpio_install_isr_service() firste[0m
e[0;31mE (25565096), call gpio_install_isr_service() firste[0m
e[0;31mE (25565096), call gpio_install_isr_service() firste[0m
…
More often though, LB is able to communicate again if I let it sit for a while with the software closed before I relaunch it…and, sometimes, unpredictably, it homes without any issues.
This is a bit frustrating, because after restarting LB, the laser needs to homed again because the bounce-back from the limit switches is +3 on both axes and it believes that starting position is zero in the absence of a successful home. The net effect of all this is that sometimes, I need to restart and home several times before being able to cut following a successful home.
This has made me avoid homing very often, which means that the limit switches are always compressed between cuts, without homing (because it returns to 0.0 after every cut). I’m not sure of the long-term consequences of the switch compression, but I’d like to avoid it if I can.
This only happens with homing. I can send dozens of click to move, or jog commands, or repeatedly send cuts without a problem - until I home.
Does anyone have any suggestions?
Thanks in advance,
