I have a Yorahome 6550 and had Lightburn working fine on my computer when I was running Windows. I switched my control PC to Linux (Pop-OS which is based on Ubuntu) and downloaded the Lightburn Linux version and installed it. The software runs fine, except that it doesn’t recognize my laser. I contacted Yorahome to see if I needed a driver or something, and their response was they don’t support Linux - even though their website says you need a computer running Windows, Mac or Linux. Their suggestion was to contract Lightburn. Can anyone give me guidance on how I can connect Lightburn to the GRBL control on my laser?
You would normally not need to do a driver install. Are you well-versed in Linux systems?
Can you confirm that the device is being detected. Can you run this in a terminal?
dmesg | grep ch34
lsmod | grep ch34
ls /dev/ttyUSB*
It’s also very possible that “Find my laser” will not auto-detect your laser. You may need to create the laser manually. If the commands above show positive results I suggest you try creating manually.
I’m somewhat well-versed in Linux. Lots of work with Raspberry Pis, but not so much with x86 machines. I’m getting ready for a Zoom Call right now so I will try this later. I can say that if I run lsusb, the laser controller does show up. I have tried creating the device manually, but when I try to issue a command like “Frame” it reports that it doesn’t appear that my laser is connected.
OK, so I ran the first set of commands and got this:
ed@pop-os:~$ sudo dmesg | grep ch34
[ 20.882329] usbcore: registered new interface driver ch341
[ 20.882344] usbserial: USB Serial support registered for ch341-uart
[ 20.882358] ch341 1-1:1.0: ch341-uart converter detected
[ 20.882841] usb 1-1: ch341-uart converter now attached to ttyUSB0
[ 23.783438] usb 1-1: usbfs: interface 0 claimed by ch341 while ‘brltty’ sets config #1
[ 23.784075] ch341-uart ttyUSB0: ch341-uart converter now disconnected from ttyUSB0
[ 23.784100] ch341 1-1:1.0: device disconnected
YES - fantastic. That was it. I commented out the line and it is working fine now.
One other question though - I don’t see a Fire button in the Linux version for aligning the laser to the workpiece - is it there someplace that I am missing?
