I’m experiencing a few issues with LightBurn and my Atomstack A40 Pro V2, and I could use some help troubleshooting. Here are the main problems I’m facing:
First, the homing function isn’t working properly. When I try to home the machine, it makes a loud grinding sound and beeps a few times, and it doesn’t seem to recognize the limit switches.
Second, I’m unable to use the alignment tools in LightBurn. Even when the shape is selected and the bounding box appears, the alignment tools remain greyed out. This happens even after restarting the software and ensuring the shape is fully selected.
I’ve tried checking the limit switches, resetting the homing settings, and reinstalling LightBurn, but the issues persist. Any advice or suggestions would be greatly appreciated. Also, I am working off a laptop Windows 10.
Thank you in advance!
Codes I am getting:

Is this a new machine or a new problem that just occured?
You need to get the device homing properly before worrying about anything else. Does it move in the correct direction toward the limit switches? Which corner is that?
If it moves toward the limit switches, but they don’t stop the machine you need to check their function. With the laser at the opposite corner of the switches, click home, then activate the switches with your fingers. Be careful you don’t get your fingers pinched. The movement should stop in each direction as the corresponding switch is pressed. If both switches stop laser movement then one or both switches need to be adjusted. If one or both switches fail to stop the movement then you have either faulty switches, faulty wiring / connection or a controller issue.
It is a new machine and I’m a first timer. When home is clicked it just beeps. It doesn’t move at all. When going to frame it does move and outline but clearly something isn’t communicating. The air also was working but now it is not. I know this is newbie user error, but I can’t figure it out. Thank you for your advice in advance.
OK, let’s get some basic info. Post a picture of your machine from above showing the limit switches. In the Console window in Lightburn type $$ then press enter. Copy and paste all the output. Post a screenshot (not a cell phone pic) of your entire Lightburn screen with your project loaded and the Cuts/Layers Panel and Laser Panel visible. Also post a screenshot of the Settings Window (Gears icon) with the Units and Grids tab visible and post a screenshot of the Device Settings Window (Wrench and Screwdriver icon).
One thing I just noticed in your screenshot above. You are set as GRBL-LPC, that should be just GRBL. Click on Devices button and edit your machine, changing it to GRBL.
First, I don’t see any limit switches on your system. If there are please show them to me and disregard the following paragraph.
Without limit switches you need to manually home the machine every time you start it up. Disable Auto Home on Startup in device settings. In the console window type $22=0 then enter. Turn off the laser and manually move the laser head to the Left Front position, then turn it on. Lightburn will recognize this as your 0,0 home position.
Second, turn off Beginner Mode in Editor Settings, you will thank me. Almost every tutorial is working with Beginner Mode off and you won’t understrand why your interface is different.
While you’re in settings, in Units and Grids, change to mm/min.
If you work in user origin, don’t move the laser by hand, use the arrow keys in the move window and be sure to set an origin point in the move window. If you move the laser by hand lightburn doesn’t know where it is.
If you use current position you can move it by hand, but I personally don’t recommend doing so.
I recommend using absolute coordinates the majority of the time. This makes the Lightburn work area a direct representation of your laser work area. Again, don’t move the laser by hand.
