Hello Andras, I’m glad that you are aware about mvl files and lack of softwares using them. I tried the raw image guess extension it’s really hard to get it right. I don’t know whether my source is right or not, can you check my file if it can be used with the extension and converted to stl or another filetype for use in meshmixer etc?

And the second question is once I determine the exact values of header size, xyz positions, spacings etc, does same values work for every mlv file obtained from the same samsung machine or I have to retune the values again for every render?

Thanks in advance, I read every post of yours about mvl files, apreciate your efforts to help people
