This is new behavior. I’ve been using LB for over a month, without issue, to control my grbl laser. I did some CNC work and then switched back to laser configuration. Now, when LB tries to connect, I get a message in the console window: “port opened waiting for response”, but it never connects. When this happens, the laser fires and the table starts to move, but with a grinding sound, not the normal smooth motion. The only way to stop it is to kill the power and unplug the USB cable.
It has happened once or twice using laserGRBL, but it is consistently failing with LB. If it does connect, it correctly reports my grbl version as 1.1f and then works fine. But it fails more often than not. Tried 6 times this morning and always failed with LB but laserGRBL connected. I’m running 0.9.04 version of LB.
Any advice would be appreciated.
