When I open a snap3dp file it shows an asterisk immediately while opening, indicating that changes are made to the file. As I did not do anything at this time, I am asking myself (and the folks here) what changes are made? I don’t see any.
When I close Luban, it asks me if I want to save the changes. I did this and compared the original and the newly saved file and they are different. This does not happen for snapcnc and snaplzr files.
Has anyone seen this as well and maybe found out what is changed?
This happens to me randomly with .stl and .obj files too. It’s been going on for a while. I do most of my work on MacOS, if that matters.
It seems to happen more to files I download from the internet than files I create. I know MacOS tracks metadata about downloaded files, so it can warn about things like executables being run for the first time. I assumed it was related to this, but I never bothered to verify.
Cura sometimes does it to, so it’s not just Luban.
OK. I forgot to mention that this is on a windows version. I tried win10 and win 11 on two different PC’s with the same result.
…and it was a new file from the same Luban Version 4.14.0.
Here is what I just did again:
Create a simple object (A Box with Sketchup) and export .stl.
Open Luban, click on 3D Printing and place this object on the table (Folder symbol on the left).
In the right window click on normal print.
Save this as a .snap3dp file and close Luban.
Make a copy of this file.
Start Luban again and load the just created file.
Click on the close cross top right and Luban asks you if you want to save the changes.
Click on Save.
Compare the copy from Step 5 with the just saved file and see they are different in size and content.
I repeated this 3 times and on every try the file was different to the previous one. This means Luban is changing the snap3dp file every time you just open it, but I did not find out, what was changed.
I also tried stl files from different sources, but as expected I had the same result.
Maybe I find some time in the afternoon to try it on earlier versions of Luban. I will keep you updated.
