I posted in November that after setting the steps/mm I was getting perfect circles from LightBurn.
I’ve not changed my machine in any way and have also checked it over a few times.
Now whenever I try to burn a circle, either from a file created elsewhere or by using the circle drawing tool in LightBurn I’m not getting a proper burn all the way round.
In the image below are 4 seperate burns of the same file, all made with different speed and power settings.
If you look at the top left and bottom right sections of the circles of each one the burn is fine.
When it gets to burning the top right and bottom left it’s a bit of a mess.
I have no idea why and would really appreciate any ideas anyone may have.
