I have an Atomstack A30 Pro. I keep getting In LightBurn the Message is: “err:limit Check ALARM:1 Hard limit triggered. Machine position is likely lost due to sudden and immediate halt. Re-homing is highly recommended.” message and will not run. How or what do I need to do to get this corrected??
You need to tell us what you are doing that causes this alarm.
The message is very plain, your design was too close to the edge of the machine travel limits and you hit a switch. This often shows up when you are doing an image and the Overscan in the Cuts/Layers window is set too high.
When I turn on the laser it beeps once normally. It doesn’t home like it normally does (lower left corner of the bed). When I open Lightburn it beeps twice and gives the error message “ALARM 1: Hard limit triggered. Machine position is likely lost due to sudden and immediate halt. Re-homing is highly recommended”.
When I select the Home button or any other button it gives the message again. I have done everything from unplugging the laser and even uninstalling Lightburn and reinstalling the program itself. I am at a total loss of what to do.
I haven’t been able to start a project in order to get the machine to go out of bounds.
This suggests you have a stuck limit switch, or a short in the wiring.
Power everything up just like you described. In the Console window, enter ? And copy-paste the line after it into your Reply.
This should tell us which switch is bad.

<Idle|MPos:-120.000,9.230,-5.990|FS:0,0|Pn:XYZ|Ov:100,100,100|APP:33|USB:0>
ok
Pn:XYZ
This says all 3 switches are closed. Is this a new wiring job or switch installation?
not a new wiring job or anything. I checked all the connections and made sure they were seated properly. everything looks to be good. Now for some reason when I select the “move” option and check the movement, everything is reversed. I went into options setting and made sure the X&Y wasn’t reversed. ……anyone want to buy an Atomstack??? ugh
This can be a Origin setting issue. Sometines it get changed by accident. If that is correct, this and the next line may be related.
Switches: Unplug all of them from the controller board and run the ? query again. Put the “<Idle|MPos:” line in your reply.
