I found a strange bug in 4.03 which is not present in the older versions. When loading a svg file in the laser program it will not preview the end file. It starts at 5.0 procent and stays there. I waited a long time but it is completely frozen. Tried loading a png or jpg file in 4.03 and it runs smoothly. Also older version of Luban i have do work good with the same svg files. So it looks like there is a slight problem with the transparant svg files, as the transparant png files do work well.
Upload your file here and share your OS version.
Did you try to edit with inkscape and save it a bit different?
I don’t use inkscape. I always use adobe illustrator to make vector images. And as mentioned it works in any version but 4.03 so there must besomething in that software version that is malfunctioning.
