Atomstack A5 pro+ not connectable to LightBurn

I have an Atomstack A5 pro+ on a Windows 10 PC. The laser is recognised with LaserGRBL without any problems - but unfortunately Lightburn does not recognise it. What could be the reason for this?

Many thanks in advance

If that’s the case then use “Create Manually” to setup the device manually. Auto-detection does not always work.


  1. GRBL
  2. Serial/USB
  3. Pick your own name
  4. 410x400mm
  5. origin front-left
  6. Disable auto-home if your machine does not have limit switches. If it does, then leave auto-home enabled.
