Hi Guys,
I have the following problem: When doing circles they are not getting parallel. I have a file, which contains 8 circles. I created 4 circles, then made 8 of them with the offset tool and used an offset of 0.5mm. Lightburn makes the laser move some circles clockwise some counter clockwise. When the laser moves clockwise for both close lines they are parallel. When the laser moves one line clockwise and the other counter clockwise they are not parallel. You can see this at the pictures attached (hope you can understand what I am trying to explain )
Here is video to show what Iām meaning: Video
This problem always happens at the same position of the circles. It also does not matter where Iā positioning the material inside the frame.
I have two separate laser machines and both are showing the exact same behaviour. Because of that I am pretty sure that itās not caused from a mechanical problem.
This behaviour also happens when using offset fill. I attached a picture of this too.
Any help is very much appreciated. I have tried everything and really have not any ideas left.
PS: For me it would also absolutely be ok, if there was an option to tell Lightburn to do circles only in one direction. But I was not able to find a possibility to do this.
Click the icon highlighted on the left and your circle. Then hold down shift and click on the arrow and it will change direction and make the laser go the other way.
Mike thank you very much! This quite helps a lot if using the ālineā mode.
Unfortunately it has no impact when using offset fill - the laser is still going both direction for every circle.
Ya, could be one way to do it.
But only if you create the graphic on your own in LB. If you import a vector file into LB and want to choose offset fill the problem still exists.
Hi John,
Iām comparing two lasers of the same model. Both lasers are a Sculpfun S10. I have ordered an additional S10, because I wasnāt able to fix the problem with the first one. But then I noticed that the second S10 also has the same problem.
The used speeds for the fill and also the line was 2400 mm/min. I have not activated lead-in in the layer settings.
Did you check the mechanics carefully? Sometimes, the grub screws holding the pulleys on the motors are not fastened enough. This could lead to some backlash if the laser changes direction.
Here is a guide to go through: Guide to mechanical adjustments and maintenance
Make sure the linear rail is running fine and the y-axis wheels and belts are tightened correctly.
Thatās true, but on the other hand, if both are produced the same way and set up the same way, it might happen. So for example, if you tighten the belts too much, you might did it on both. Not saying that you did. But to me, it looks like a mechanical problem. I would be very surprised if a software setting can cause this.
For sure, you are right. But I really checked everything a lot of times. For example, I tried tighten the belts very strong and then checked the result. Then I tried tighten the belts very soft and checked the result. Same with the wheels and the eccentric nut. And no matter what I have done, the result was always the same.
Oh that would be awesome. I did not have the possibility to compare to a S10 from another user yet. Thank you very much.

Iād say mine looks ok. I didnāt change the settings from the file. The laser used the same pattern as in your video - the outer circles were done in two directions each.
