When I CtrlC and then CtrlV to copy and paste a piece of design, I have noticed that LightBurn will often (usually) go over the same cuts twice.
This didn’t use to happen.
I am using the latest LB on a Linux machine and then transferring the results to a Windows 10 machine, that is downstairs and runs the lasers.
I have one red and black laser, and one China Blue. They both use Ruida controllers.
Does anybody have any insight as to why this is happening?
You might have inadvertently pasted a second copy of the design directly on top of the old one, select and move to see if there are 2, if so delete 1. I’ve done this a few times.
I thought of that Terry, and I did try removing any extra copies. It isn’t that.
Thanks for your reply
I have selected that option, and now that I think of it, this only started happening recently after I did make that selection.
So, why would the removal of overlapping lines cause a double burn? It seems entirely non-intuitive.
I made a mistake. I did NOT have “remove overlapping lines” turned on after all. Maybe I should?
Post a file that’s doing this here so we can have a look (or email it to support@lightburnsoftware.com if you’re not comfortable posting it in public).
There are a number of ways this could happen - duplicate shapes is the obvious one, but you might also have your layer set to make multiple passes.
Oz found the problem.
I had inadvertently set the number of pass counts (under cuts/layers tab) to four.
I have no idea how I did this and I was not aware that the setting even existed.
So - my stupidity. The software is much cleverer than me.
