hi there, have some DXF import issue again.
I tried to import the cutting file from https://www.instructables.com/Laser-Cut-Firemans-Phone-Stand/ (https://content.instructables.com/ORIG/F6M/092I/I27GRXGF/F6M092II27GRXGF.dxf) and this is the result:
Using 0.9.19 Linux version. Maybe some dxf library linked to LightBurn binary?
this is the list of libraries “out of LB tree”:

Desn’t seem there’s some DXF reading library from the system… anyway, I didn’t find any string “dxf” in all libraries names. So I can’t imagine, why you say that dxf import in your 0.9.19 version is different to mine 
tloudev@stodolar /usr/local $ grep -ri dxf LightBurn/* |grep -v lang
Binary file LightBurn/AppRun matches
Binary file LightBurn/LightBurn matches
Binary file LightBurn/lib/libicudata.so.56 matches
But this library comes with LightBurn, so it should use the same behavior, shouldn’t it?
So, I downloaded and installed 0.9.20 right now, and teh result is still the same
hmmm… so something wrong with my linux Mint Please be so kind and export it for me to lbrn, I swear this is the (first and) last time… thanks.
LightBurn doesn’t use external libraries for file importing - I wrote all the importers from scratch.
That said, this file comes in very small, so my suspicion is that you have the DXF Auto-Close setting too high, and it’s merging vertices that shouldn’t be.
What do you have this set to?
HA! That’s it! I have 1.000mm tolerance. After decreasing to 0.001 the image is OK. THANK YOU BOTH guys.
1mm is huge for that setting. I usually default it to 0.01mm, maybe 0.05mm. Personally I have my own set to zero, so things have to be exact to be joined.
