I used your attached file and did the "generate an elephant foot calibration test and save it" but it does not raise any error to me. File was saved and reloaded fine. Are you sure you have the correct file attached? |
|
Thank you for testing - I will doublecheck my file once I’m back home, tomorrow at the latest. |
|
Yes I've doublechecked, issue remains. So to be precise:
I will now check on Windows 10 and the newest UV Tools version there. |
|
I cannot reproduce the issue on Windows 10: good to know that it works well there. Will reinstall on macOS Monterey and also try macOS Sequioa on another machine. |
|
Fresh install on macOS Sequioa on different machine (iMac18,3): same issue Reinstall on Mac Pro detailed above: same issue Will try my third machine: macOS Sequoia, arm64 |
|
macOS Sequoia arm64 is a non-starter for me...

The problem is with lychee slicer not setting a MachineName on file, resulting somehow on a
Windows and macOS have no difference in file format logic, there are no IF regarding OSes.
Never manual install UVtools on macOS, always use the auto-installer script, stated on readme page. |
|
I used the same file in Windows, downloaded from the link above here.
I see... I assumed the zip files on the releases page could be used as-is. Installing with the script on arm64 works but issue remains. Same for reinstalling on macOS x64. I will bring this issue to the attention of the Lychee team. By the way, I had missed that the current Lychee version is 7.2.2, but this issue is present there also. |
