Printer model

MK4

Firmware version

6.2.0-alpha1

Upgrades and modifications

None

Printing from...

USB drive via Prusa Link

Describe the bug

At the end of each print, the print bed moves forward, the heaters turnoff, and the print head parks. Prior to this alpha update, the Y-axis stepper motor deenergized immediate after moving forward. With this update the motor stays energized for several minutes.

Not sure if this was intentionally, but it certainly doesn't seem necessary.

How to reproduce

print any object. This behaviour it is very persistant

Expected behavior

The print bed should freely move after a print.

Confirmed, this is really happening in 6.2.0-alpha1 and not happening in 6.1.3

Created internal ticket for investigation.
