The alarm you received means that while homing itself, your laser lost it’s position. It needs to be homed before it can continue. Do you know if your laser has limit switches? If it doesn’t, you will need to manually home the machine. GRBL Configuration - LightBurn Documentation
I would also encourage you to learn more about the different ‘start from’ positions in LightBurn: https://www.youtube.com/watch?v=aphiLTUWcjE
Tks for feedback. I have an Atomstack 30x with ( i believe ) limit switch ( front left ). I did manual homing, as you said, I reloaded the lightburn SW, I switched all out and on,… It does not work. I show you pictures
1 ) before starting
I am trying many things, without really knowing, what I do and I am running crazy. I need to lazer a board until coming weekend for my grandchildren. Please help me!!!
Kind regards, Peer
It sounds like you have ‘auto home on startup’ enabled. In your device settings, make sure you have that option disabled.
“when I push 3xright it goes right left left or right left right…”
Inspect your wiring for damage, if the laser isn’t responding to your jog commands, the first thing to check would be damage to the wiring, especially if it’s only working intermittently.
Hi and many thanks for your support. With the auto home buttom and wiring plugging out and in, the lazer works now, which is great, but there is now another issue: after lazering an image the dimensions are 82x69 mm instead of 133x110mm. What shall I do?
Thanks in advance!!! Peer
Hi, to even better illustrate, what I meant above is shown in below fotos: in lightburn I have a 100x100 mm box , after lazer it was 63x67 mm ( x Y )
Thank you for the photos, it would appear that you need to calibrate your axis! Here’s how:
Before calibrating your axis, double check that you haven’t accidentally altered your x/y/z steps. 80-100 is the expected range. What does your laser report for $100 $101 $102 if you type $$ in your console?
Hi,
-1) first thank you for your Axis calibration hints, it worked out and the dimensions are perfekt!!
2) Your last comment i did not understand what $100 … is for , but I typed $$ into my console with enter without any reaction see foto
3) I have a further issue, hopefully the last, : the lazer stopped after approx 30 min, while just 1/3 of the job was done ( see photo ), the console said that the connection was interrupted, but I did not touch the lazer or labtop… what shall I do.
Thank you so much, I really appreciate the dialogue with you :))))

Hi, As complementary information to above I like to add that I restarted the job at 33:11 min at the "tv screen - prediction ) where I could tick the box under “start from here”.
see the photos.
Tks for your advise:)

… I forgot to mention that the lazer is connected with the Mack book via Cable and I did not change anything in the environmential electricity - did not switch the light off/on …
thanks for your help, one lazer job worked perfectly, the second lazer job was again stopped, while the computer was not in sleeping modus. See the photos…
What can I do ?
It really looks like you have an unstable USB connection. First, exchange the USB cable with a new one. Then, try different ports on the PC. If you only have USB-C ports, try different USB hubs, do not use a USB-C-USB-A cable.
The connection was interrupted, make sure the cable isn’t being shifted by the laser, then I would invest in a better cable. USB extenders can cause interruptions too. Make sure the USB cable has a ferrite at each end and is also shielded. The power supply cable and the usb usually enter the machine right next to each other, so any interference gets a good chance of messing up the data over the usb.
Thank you,
Info : I have 2 USB C plugs on my MacBook, I tried both, I tried in total 3 different cables ( a new one with ferrit is ordered, expected for tomorrow ), nothing touches the cable. → no success.
Interesstingly, in the past it worked ( the photo shows the cables I use )
Now there is something additional and strange: after job start the lazer is a bit vibrating, continues and vibrates again, after it stopped quickly.
Console Info see photo
short, before I wrote to you first time I had uploaded a S/W update
Thank you for your help,
Peer
Please type $$ into your console, while the laser is connected, and paste what it copies to your clipboard in a reply back.
Vibrating is not good and points to a loose or broken cable. Can you tell where the vibrating is coming from? I would inspect the cables for whichever motor it may be.
This is not a good way of doing it. Add a USB hub. This has helped tons of Mac users. Do not use any adaptors from USB-C to USB-A.
Sorry to step in.
AS @misken wrote a cheap USB2.0 hub.
Hi,
I did, what you told me:
I types $$ ( see photo )
I bought a cable 2.0 high quality and a usb hub ( see photos )
I checked loose cables , none
The whole frame with the motor is vibrating soon after start, just for seconds, vibration stopps and after it restarts again , after the lazer stopps and goes to startposition.
The vibration is nes since I wrote it to you, never before…
What shall I do?
Tks, Peer
