Every Job Ends in Error 9 GCode Locked

Hello All,
First time poster, first time visitor.

I am just now getting my feet wet with the Lightburn software. I am mainly using it to send jobs to my Ortur Laser Master 3. I have not tried designing in it much.

I have been toying around with burning DXF files i have drawn. Everytime the project completes, i get the errors “Error:9 G-code locked out during alarm or jog state” and I am stuck. The only way around it is to shut the LM3 down and start it back up again.

This is the info from the console:

I’m not super familiar with the Ortur Laser Master 3. Does it home when you turn the machine on?

If not, are you manually homing by putting the laser head at the front-left before starting the machine?

If the machine does not home and you are not manually homing, suggest you do so and retrying. It’s possible that the laser controller believes it’s going out of bounds when it’s actually not.

It homes when turn on. I can drive it around using Move in LB before starting a project.

Somehow you’re exceeding the bounds of the machine. Can you try placing a single small object in the middle of the workspace and try burning that? Do you get the same issue?

If so, then likely something in the design itself.

Post a full screenshot of Lightburn with the design loaded or upload the .lbrn file here if you’d like it reviewed.

Mine always shows the error at startup. I turn on the laser and then the software. The Sculpfun does go to the home position and everything works properly. To me, it is just a useless alarm that doesn’t affect the operation of the machine. But LightBurn does need to look into this issue

This is not a LightBurn message. It’s generated by the controller.

In your particular case it’s likely caused by a particular sequence of events combined with how your firmware has been configured. At the end of the day since you’re able to home successfully after that it’s a non-issue but there’s likely something that’s causing the message but one that just doesn’t amount to anything.

In the case of the original poster I’m more concerned with the ALARM:2 which is really the source of potential issues in the burn, not the later error:9.

I winged it when connecting LB to my engraver. Perhaps it is setup wrong causing all the issues?

If you can confirm that it works on a simple object in the middle of your workspace I think you can rule out any major configuration issue. Likely more design related.
