Project is burned/cut as a mirror image

LightBurn Software Questions
1

I was following the lightburn beginner video 1. The project looked fine on the screen, but when two things happened:

  1. when I used frame the dimensions were about 30x bigger than what I set them at
  2. the project was burned as a mirror image to what I created on the screen.

Any suggestions would be welcome.

Are you saying that the final burned dimensions are 30x bigger than the designed dimensions within LightBurn? If so, you can calibrate your axes in Edit->Machine Settings->Calibrate Axis

This is typically caused by a misconfigured Origin setting in Edit->Device Settings. Your machine is likely meant to be set to front-left.

You are using mm and outputting inches, make sure all setting are consistant in either mm or inches. The mirror image is usually from incorrectly set origin.

Thank you - I did check and everything is in MM. I remeasured my area and made sure the work space was the correct size and the offset as well. I am new at this and very confused.

5

Thank you - checked what you suggested
I tried to calibrate the axes - but the window asks for a requested distance and an actual distance - I am not sure what to put in here…
they both read 200 currently

6

Requested distance refers to the size as designed. Actual distance refers to the size actually burned.

Can you do one thing? Run this command in Console and return the full text output here please?

I was curious about this setting. If set to 1 the controller will report in inches. That’s not the case here so you should be good to go in that regard.

These define the number of steps per mm of travel for X, Y, and Z respectively. Typically X and Y are the same assuming you have the same stepper driver and motor. Are you getting twice as much travel on X as Y?

9

Yes the X is moving 2x as much as the y
So I should change it to???

10

The easiest way to go about this is to use Edit->Machine Settings->Calibrate Axis.

However, if X is moving exactly 2x Y and Y is otherwise cutting to the correct dimensions then just change it directly.

Enter this in Console:

$100=250
