It looks I found the problem.
The variants settings work wrong. I have 3 variants of settings and in my definition file I set the printer "has_variants" as true. Also, 3 variants of file configuration in Variants folder. Also, the default variant was set in printer defination.
But when I add my printer, all my extruders are empty, without nozzles. And I cant change it. In this case the quality settings are not available.
If I set "has_variants" in false, the quality settings are available, but not all (I dont understend why). I have 4 quality settings, but only 3 are avaliable.
Why its happend? In bug report for version 4.4.1 shown that this problem was solved. What I made wrong?
