To whom it may concern,
It is “common” (for me) when start working for a project with Lightburn, having Laser off (Sculpfun S30), at the moment starting laser ON and choosing correct COMM Port X, software crashes by not responding.
It has to be hard closed, so all project updates could be missed.
There is any chance to make USB port selection process more robust, like a “timeout connection message” or similar?
Thank yoou in advance!!!
Sometimes using a ferrite core USB cable solves many communication problems.
Are you using a cable identical to this?:
I have the same setup as you. Occasionally but rarely, the software will go stupid on the COM port. Like you say, total restart is needed.
Unfortunately, this is not a Lightburn or laser thing. It is Windows, which has total control of USB devices, messing with port assignments.
I never has a software “crash”. Can you provide more detail?
Hi Mike! Yes, I agree but some software have a “Failure recover” procedure to avoid “crash”.
“crash” meaning when a program/software never stops performing ie: falls in a bucle with no response to inputs. It could continue forever. Until it is “terminated” by operating system or machine hard reset (turned off).
I appreciate your comments, hopefully LB could get fail safe features.
Regards
You mean you want Lightburn to magically know when Windows screws up? Even Windows does not know when it screws up.
Excellent!
Is there a possibility that the connectors are worn out and making poor contact?
Are you able (are you aware) of how to see in Windows (control panel) which port Windows detects when connecting and disconnecting the cable?
It is important to understand whether Windows is doing its part. If don’t, the lightburn can’t do it’s own
Is as @MikeyH said:
