The laser stops firing in the meddle of the job but the head doesn’t stops. When that happens, the head eventually stops, moves back and tries to keep engraving where it stops. The problem with that is that when that happens it never restart in the same position, making a really noticeable line along the path. That line is just shifted from the “original path” that the laser was supposed to follow. It does that no matter if the engraving is vector or raster. Please help!
Sounds like a temporary loss of connection to the laser, so the head keeps moving until the connection is remade and then it continues. While you didn’t state what laser or anything of your setup, I would suggest trying a different USB cable if you’re tethered directly to Lightburn. Maybe a higher quality one with ferrites. Also make sure you’re not maxing out your PC resources causing lag.
Thanks for the quick response. It seems like a connection type of problem, yes or even buffering. Is it possible to get around that without a new cable? I’m in the middle of nowhere and it’ll take me hours (literally) to go get a new cable from the nearest town. What about buffer settings? is there any way to change them? (I just downloaded light burn today, still pretty new)
Using buffered is usually better, as it keeps the command buffer full. However, if the cable is losing instructions without the ‘ok’ response, synchronous might help. While if it misses an instruction, it should only be one vs however many got lost during the disconnect. It’s usually slower when sending things with a lot of tiny movements, but for just text, you should be good to try it.
I’ve been looking everywhere for the Synchronous dropdown menu and it’s not there, probably I have a different machine type. It’s supposed to be in the device settings but it’s not there.
Oh, are you connecting to your machine over wifi? Dropped packets would definitely cause problems. I don’t have any machines I can run over wifi with lightburn, so I have no experience with that.
No is not WiFi, is cable (USB-B to USB-A)
If possible, a LAN connection is always to prefer. (But I’m not sure it’s your problem with those lines)
It’ll probably just work itself out before you get to Exodus.
Hello! I have the exact same problem with my Gweike Cloud CO2 50W.
I have tried both with LAN-cable, USB-cable and also unplugging all cables after sending the file to the machine. Someone has any other idea how to continue the problem solving? Or is it still the file transfering process which may cause this problem? My computer is rather old (8 years on its neck).
I’m happy to provide any pictures / videos or files you need in order to help me resolve this issue.
Thanks in advance!
