Layer shift at colour change due to the nozzle wiper

Having some issues today on two A1 printers, not sure if there was a change in the new Bambu Studio, but I am getting layer shifts on one A1 and it looks like it’s after purging it catches on the wiper somehow, goes to purge block and immediately is off about 1mm to the right.

I have another print running on another A1 and at the same point after purging it looks to be catching, except this one is recovering, moving the nozzle up before getting to the wipe tower.

Update: the one currently still running is actually colliding with the wiper worse, it does the purge, flicks off and as it tries to go to the purge block it whacks part of the wiper and rehomes

Anyone else having this happen since the updated software?

Update: 2 Known issue according to Wiki with 1.9.7.50 upgraded to 1.9.7.52 and testing.

Seems ok with 1.9.7.52 in case anyone else has this. I did not get a notification about a new version so may be people still on the bugged version.

There was an update that had something to do with an issue like this. Have you updated Studio?

Hi, yes updated Studio and it’s fixed the issue.

Luckily some prints survived even with the bug.
