image being flipped upside down and backwards when filling

LightBurn Software Questions

After not using my XTOOL D1 pro (grbl) for a few months, I had to reinstall the Lightburn software now…

If use “line” to engrave a .svg, and the origin is set to the upper left corner, the machine moves correctly +x +y. If I set the same vector to “fill” (same origin) the machine moves to the lower left corner and moves -x -y . some how the coordinate is being flipped when I change to fill.

I have confirmed this behavior by creating a simple rectangle in grieving it as a line and then engraving as a filled vector and when I fill the object the machine moves in the wrong direction.

I am using the latest version of lightburn. I also rolled back to the previous approved version and the behavior did not change.

I have been using lightburn for over a year and did not have this problem until this week. I cannot understand what may have changed.

Thank you.

Post 2 project files (.lbrn2) one as line and one as fill.

In line mode the laser moves correctly and engraves the material, origin upper left corner.

fill_mode
fill_mode780×321 13.9 KB

In fill mode the laser makes a rapid move down past the material and then moves slowly to the left until hitting the machine limit switch.

Problem does not occur in software version 1.4.05

What Lightburn version and D1 Pro firmware?
I recall reading something about XTool changes in latest firmware.

I can’t tell you what the Xtool version firmware is right now, but it has not been updated since I bought it and that was over a year ago.

Problem exists with lightburn software versions 1.6 and 1.5. there is no problem when running version 1.4

Save 2 .gc files:

  1. As line click Save GCode
  2. As fill click Save GCode
    Post here the resulting files for us to check.

So now that I have software that works and a functioning laser that I can actually use, you want me to uninstall software that works and then load software that I know does not work to save these files for you to diagnose?

Unfortunately, given the number of things in preferences that can affect the output, that’s the simplest way to do it.

The installation process is fast, and it should just be a matter of you loading that simple rectangle project in both versions and hitting “Save GCode”. Then you can just re-run the installer for the one you know works.

OK, now I don’t know what to say. I re-installed version 1.6.03 and everything works!

There was a warning that something needed to be closed to be updated. The dialog could not close the item so I selected continue anyway. Is there an install log so we can find out what I did?

So sorry and thank you,

Larry

The only way to know what changed would be to compare your settings from the current install the the previous one.
