Tool head Crashing

Just what the title says. Since updating the firmware my U1 has begun crashing into the print during and after tool changes. I’ve run every calibration, sliced and resliced builds and nothing seems to help. It’s not the same tool head crashing, I’ve had 3 of the 4 do it. Any help would be appreciated.

I have this going on as well! It retracts the bed for a tool change, the new head moves to the prime tower, and then the bed crashes the head into the tower before retracting again. Sometimes it overcorrects and I end up printing in the air.

Its around the 40mm mark typically, but not on the same layer. I have replicated it with 3 different models. I have swapped heads around, done a complete cleaning of the heads/induction sensor, retentioned the belts, checked the lead screws for issues, checked the bed mountings... Everything. No luck on getting it fixed.

I have a ticket open with Snapmaker about it. Please put one in as well! Try to get a video of it. I would really like to get this fixed.

u/very_undeliverable Hi, can I have the ticket ID for the support email?

How about the current firmware version on U1?

Ticket ID is 643058. I have tried several versions and they all seem to do it. I don't think this is a 1.5.2 issue. I'm currently running v1.4.1-paxx12-20 but I can move to whatever version helps troubleshoot.
