[BUG] Loaded XL carriage crashes into parked tool #4259

Printer model

XL

Firmware version

6.2.0-alpha2

Upgrades and modifications

None

Printing from...

PrusaLink

Describe the bug

I cancelled a print after it had done its first layer, because I wasn't happy with the bed adhesion. The carriage (loaded with Tool 1) stopped at the back/right, just in front of Tool 5, when the print got cancelled.

I then selected "Park Tool" from the menu, which caused the carriage to ram tool 1 into tool 5 before recovering and parking the loaded tool 1.

How to reproduce

I don't dare attempting to reproduce it, it looks like my tool 5 got damaged by this.

Expected behavior

Never ram into another tool. The printer must have known the current X/Y position of the carriage and should prevent this.

Sounds similar/related to #4154 and maybe #4235.

I experienced the same on the first print I tried with this version although it crashed into tool 5 right off the bat, before printing the first layer. Tried rehoming to no avail. It keeps crashing into tool 5. I gave up on the second attempt as it's so violent I fear I've already caused damage.

I updated directly from 6.1.3 to 6.2.0-alpha2

Hey, thanks for the reports. We have identified some motion-related issues in our 6.2.0 and they should hopefully be fixed in the next candidate firmware.
