Hi
My lightburn software is really slow at saving RD files, especially after tinkering with a file like break apart then grouping again after - I get to about about 80% the it freezes, then about 10 minutes later it goes to files so I can save it - anybody else have this issue - is it worth re-installing the software?
That is hard to determine based on what you have provided, we are going to need a bit more to track this issue down:
What kind of artwork and what cut process are you after? Show the file and the settings so we can try and reproduce here.
- What version (provide the number, please) of LightBurn?
- What OS are you using?
- Are you trying to save to Networked or Remote/removable storage or local device?
You say RD file and nothing more about your setup. Please update your profile so we don’t have to ask.
80% is the start of the optimization phase, which includes overlapping line removal and path ordering. If you have a very complicated file and have "Remove Overlapping Lines’ enabled in the Optimizations this can take a long time, so I don’t recommend turning that on unless you actually need it.
More info about the kind of file you’re trying to run and the options you’re using would help us give you better advice.
Since you mentioned it, “Break Apart” is effectively shattering your shapes into the smallest possible pieces - A square becomes four lines. This can put a huge strain on the path optimizer, because instead of having a handful of closed loops that the laser follows, it has to check each and every single line or segment in the shape as a possible “next” thing to do, and rate them all by score. If a path is connected as a closed loop, the software runs the whole loop then looks for the next one.
As an example, if you create 10 octagons, since they’re closed loops the software will scan the 10 of them to find the closest one, then scan the remaining 9, then the remaining 8, and so on. This means 10+9+8+7 … it ends up being 55 things to check.
If you used “break apart” on those shapes, you’d now have 80 distinct shapes, instead of 10 shapes made of 8 lines each. Path planning would scan all 80, then 79, 78, 77, 76 … or 3240 checks to do. Remember, this is just 10 octagons. If your file is more complicated, these numbers explode really fast.
If you do use Break Apart, make sure you use ‘Auto Join’ when you’re done to put things back together into loops - grouping them doesn’t re-assemble them, it just throws them all into a bucket, but doesn’t influence job planning.
