This topic has been discussed and at least one user has had success with the Pre Release for solving this issue (or it hasn’t occured for them yet) It did not solve the problem for me, as I encountered it with the Pre Release.
I am using a Cloudray EC 30 co2 Galvo, not sure of the chip used.
While engraving using the rotary, I will often hit “Pause”, “Stop”, and then “Go to zero”, if I want to change a setting to get a more desirable outcome or if I notice something off, make my change and start again.
More often then it should (which should be never) any buttons that directly control the laser, ie. Jog, start, stop, pause, go to zero, show center, don’t work. I can exit the rotary window no issue.
I can then design, edit and use the UI as nothing is wrong, until I try and start engraving again. Now the main laser window control functions do not respond, ie. frame, pause, stop, start.
The status of the laser is “framing” which it is not, I have to exit out of lightburn for it to reconnect. This is frustrating as I lose zero and have to spend a lot of time TRYING to re-zero, not always successfull.
