Makeblock rotary - not recognized by LightBurn

Your Makeblock engraver is probably the MKS-DLC32. It’s a GRBL device.
You’re in the right section, but the xTool above should be in a different channel.

The quick way to get unstuck is to set up a GRBL device manually.

Set the work area at 10mm x 10mm and select the origin front Left.

Once you’re communicating with the engraver, you can pull the information out of the engraver into LightBurn. Click Edit, then click Machine Settings, then the Read button on the right hand side of that pop-up window.

Once connected, you can get several reports out of the engraver.
In the Console window in LightBurn please request these reports by typing:
$i
$$
$#
?
Pressing enter after each one.
Please copy and paste the reports into a reply here so we can see how your engraver should be set up.
