I have just bought a COMGROW Z1 10W laser engraver. I’ve been trying to connect it to my Macbook Pro and it won’t work. It says the Laser is disconnected in the laser section, but for the (connect) option there is cu.usbserial-1420 as my option. There are no COM options. I plugged the same exact cord and laser engraver into my PC, and it connected and worked just fine. I’m not sure what to do. I’ve downloaded the specific driver that my laser engraver needs, but it’s still not working. Essentially I’ve done both the same exact things to my PC as my Macbook Pro, but the laptop isn’t working. In the Console log, it’ll say
"Waiting for connection…
Port failed to open - already in use? "
I managed to connect one to a MacBook Pro.
I used a Thunderbolt USB adapter. I’m starting to see this as fairly important. The simple adapter cables don’t seem to connect as readily or as reliably.
I used this driver.
I didn’t click OK when it asked for a password or admin access to make changes. There was one pop-up in the Mac OS that was counter to what I was trying to do.
After selecting the correct port with the letters wch in the name, if LightBurn didn’t connect, I closed LightBurn and restarted it. After that it connected on startup without issue.
It’s a weird step but it seemed to be the fix.
