D1 extensions arrive today

My D1 extensions are scheduled to arrive today. I’m looking for the instructions on how to change the work area in lightburn.

Don’t know if an official update procedure has been published from xTool as yet but you may want to read through this earlier Topic:

You can go into the device menu in the bottom right select your laser and click next till you get to where it asks for your work area then adjust accordingly and continue to click next and save. You can also set up your machine a second time in the device menu as the extended version to maintain the original setup as well.

Thank you for your response
