Connect a GRBL engraver

Use Machines → Set up my laser… to create a profile and check that LaserStudio and the controller agree on the machine settings.

Choose and save the profile

1. Choose the preset that matches your machine, or use Other GRBL laser and enter the manufacturer’s bed dimensions and serial settings.
2. Connect the USB data cable and select the COM port shown for your engraver in Windows Device Manager. If another app has the port open, close its connection.
3. Save the reviewed profile. If you use Find my laser, review the detected port before saving.

Connect and read the controller status

Choose Connect on the Laser or Move tab. The panel reports the connection and qualification state. Compare the controller’s reported travel and maximum S with the profile. Resolve any mismatch before requesting motion.

Choose the right connection panel

Use the Laser or Move tab for the positioning connection. Use Machine → Machine control for the read-only diagnostic checks and diagnostic summary. See GRBL connection and status errors if the port opens but qualification or status checks fail.
