G-code motion target exceeds machine travel?

LightBurn Software Questions
1

This is the error I get.

It started occuring after an engraving I last did got messed up. The cable got in the way of the laser at the edge of the work surface causing it to get hung up for a second.

G-code motion target exceeds machine travel. Machine position safely retained. Alarm may be unlocked. (Right-click the ‘Devices’ button to reset the connection)

Does your machine home normally at startup?

Can you run these commands in Console immediately after homing and return results?

This is what I get on start up and it does home auto in the front left or closest to me.

I don’t see anything unusual with the output. What are you using as the selection for “Start From” in Laser window?

7

User Origin.

The issue seems to have started after the laser got hung up in the upper left corner on the last job.

8

From what I can see in the output I don’t think that’s causing this particular issue.

Can you switch to Absolute Coords and then using the Map pin looking tool (set laser position) confirm that you can move to all corners of machine.

If so, you’ll likely just need to redefine your user origin. Is there a particular reason you’re using user origin and are you familiar with the nuances in using it?

9

The laser was able to travel to all corners no problem. Here is the read out:

I am not familiar with the details of user defined origins

In that case I suggest you stick with Absolute Coords as that is the most intuitive coordinate model.

I believe your machine should be functioning correctly. Continue to test.

You can learn more about the different Start From modes in this video:

Interesting, it seems to work fine using Absolute Coordinates.

Thank you!
