I have a Atomstack x7 pro with lightburn software. I’m getting this error no matter where I start the laser head.
Would appreciate it if anyone could assist.

You’re using an iLaser device type. Your laser is a GRBL device type. Go to Devices in Laser window. Then edit your laser and change device type to GRBL. Assuming other choices are correct you can leave those.

Thank you so much Berainlb. It’s working now. #newby
