I am new to both lightburn and laser engravers
I am using MacBook (Intel Chip) with Lighburn firmware V2.3 driver (COMGO Z1 Laser Engraver.lbdev)
Running ls /dev/usb I get the output: /dev/cu.usbserial-1440 /dev/tty.usbserial-1440
In the laser tab, I have devices cu.usbserial-1420 COMGO Z1 Laser
In device settings I have:
S-value max 1000,
Baud Rate: 230,400 (In have also tried 155,200 and 19,200)
On the ComGrow I have the red power light (solid on) and green light (flashing)
The command window says: “Port failed to open - already in use?” followed by waiting for connection.
Hi,
Thanks for your assistance.
I have tried all the baud rate settings. Nothing affects the waiting status.
I have used chmod 777 on usbserial in case it was a Mac auth issue. My user account is an admin one.
Suggest you follow @MikeyH advise of using 115,200 for a baud rate.
You should check your device list for your machine to ensure the laser is being seen by the os.
Lightburn will attempt to connect and right-click on the device button will cause it to retry.
If some other machine is using the target port, it will not be able to connect. If you have multiple devices via usb, might want to turn them off until this is resolved or at least when you’re working with it.
Sometimes just not plugging it in until the Mac is up and running will cure some of these… this is why I’m not a usb fan
Another are is some of the Macs are using USB 3.0 and don’t function plugged into a USB 2.0 type. Don’t remember the fix, it was an adapter that forced the machine to use USB 2.0 protocol.
I have tried 115,200. This was the 1st one I tried following the comment by @MikeyH .
I have run the command ls /dev/usb based on a search of issues getting lightburn to work on a Mac. This returns /dev/cu.usbserial-1410 /dev/tty.usbserial-1410. I think this suggests the Mac can see COMGROW Z1.
I have 4 USB ports; three of them are 3.1 ones, and the other is thunderbolt USB4. I am using a mac type A to type C converter on the end of the USB cable that came with the laser so I can plug it into the Mac. I will have a search for a USB 2.0 converter.
I also have a FusionB Windows pad. Would it be better to try Lightburn on this instead of the Mac?
Hi I have tried using a hub that has a USB 2.0 connection and also with a Windows tablet. Neither is able to connect to the laser with the same message in the console.
Command sudo find /Library/Extensions/ -iname “usbserial” returns an empty line
Command ~/Library/Extensions/ -iname “usbserial” returns No such file or directory
So the Apply apply one is used
2) Check computer and laser connected ls /dev/*usb* returns /dev/cu.usbserial-240 /dev/tty.usbserial-240
Lightburn devices row has cu.usbserial-240. grbl COMGO Z1 Laser Engraver
Console says waiting for connection
I have downloaded the APP and the cutter works to engrave but the iOS app does not have a cut option. The issue is therefore linked to the connection from MacBook to the laser.
