I purchased but have not yet received a TT-5.5 Laser Engraver.
The specifications list Windows only, but also say that LightBurn is a supported software.
My only available computer is an old Mac Mini, which I am on now.
I installed LightBurn successfully, but Two Trees is not an option to select from the Device List.
How do I use Light Burn with my Two Trees hardware from a Mac?
In the Laser window in LightBurn, What options are available when you click the middle button in the bottom row? Sometimes it’s just a matter of finding which communication port was assigned.
Open the Console window. You should see a welcome or wake-up message from the engraver once the communication is established for your Mac Mini.
If it helps, I’m hitting the same issue. There doesn’t seem to be a usbmodem or usbserial port established, but the Mac does see the USB connection in System Profiler:
USB Serial:
Product ID: 0x7523
Vendor ID: 0x1a86
Version: 81.31
Speed: Up to 12 Mb/s
Location ID: 0x00100000 / 1
Current Available (mA): 500
Current Required (mA): 98
Extra Operating Current (mA): 0
I’m pretty sure I’ve coached the C340 driver install at least a dozen times by now… It feels like about 50 times though.
For the driver, I send folks to this Instructables link (step 5). I like the ample leading and trailing context including chip identification if you want to pry into it and understand more.
If you can expose and see the control board you may see the chip responsible for USB communication and make a very informed decision about the driver.
