@M60A3Driver Your threads/posts are, as always, very detailed.

When my drive shaft returned from an external repair shop in Warsaw after being repaired, I didn't receive any repair report, only a photo of the machine's screen used to check the shaft.
Interestingly, the software on this machine seems to be in Russian, so perhaps the work is being done by a Ukrainian – we have many Ukrainians in Poland these days.

Does this screenshot tell you anything?
