Lines go outside of my test squares

Hello!

When I try printing LightBurn’s Material Test on a white tile (with the Titanium Dioxide method), there are several lines which are coming out from my squares printed (see the image below). Any ideas what could cause this? I’m using an AtomStack X7 Pro with LightBurn. Thank you!

Check for Lead-in/Lead-out settings under Advanced in your Cut Settings.

Thanks for your reply. Unfortunately I don’t have lead-in lead-out setting in the Advanced tab:

Any other ideas?

Can you confirm that the pattern was created in LightBurn Material Test Generator? If so, can you push “Edit Material Setting” there?

I’m assuming you have 2 sublayers defined, one for line and one for fill. Check the line sublayer in Advanced tab for a lead in/lead-out.

If you cannot find anything like that then push “Save gcode” in the Material Test Generator, save to a file with .txt extension and then upload that file here please.

It is generated with the LightBurn’s Material Test Generator.

I don’t have sublayers in the “Edit Material” settings, only one with the “Fill”.

Here is my test file in .gc and .txt formats:

ps.: if I change the mode from “Fill” to “Line”, I have the Lead-in & Lead-out setting, but I need the test with fill of course…

I don’t see anything like this in the gcode. This likely isolates the issue to something on the hardware or configuration side.

Are you having this issue anywhere else or just on this job?

Can you run this command in Console and return the output?

I have only on white tile (NWT method).

About the console stuff (sorry if I mistaken something), it didn’t return anything:

I’m wondering if the process is just very sensitive and your laser is turning off slowly.

That’s odd. Can you reconnect and try again? If nothing is returned that indicates a different problem. In that case, I’d recommend a reflash of the firmware.

This is what the $$ returned after reconnecting:

ok

I don’t see anything there that would potentially cause this.

In that case it’s likely a firmware issue or a hardware malfunction. Seems like your laser is either firing early or staying on longer than it should. The latter seems more plausible. You can determine this by checking if the artifact is occurring at the start or end of the burn.

If I had to guess I’d think that the issue would be in the laser module. However, the issue could still be in the controller or even power supply.

Thank you for your help and quick replies! :blush:
