Prusa XL Crashes If Stopped Mid Print & Then Tool Parked that is Not Tool 1.  

Prusa XL Crashes If Stopped Mid Print & Then Tool Parked that is Not Tool 1.

• Prusa XL 5 Head
• Firmware =6.2.5+8912 (latest available as of April 28, 2025)
• PETG filament is loaded in tool #1 and tool #5

Steps to recreate the bug:

1. Start a print job.
2. Stop the print job in mid-print when tool #5 is actively being used
3. At this point the printer moves tool #5 to the rear left, in front of tool #1.
4. On the printer Control screen, instruct the printer to park the current tool.
5. At this point the printer starts a homing sequence and one of the first things it does is move the Y axis towards the rear of the printer.  Since tool #5 is still in the tool changer, tool #5 crashes into tool #1, which is parked.

This is reproducible 100% of the time.

Also note, one time when tool #5 crashed into tool #1, the printer operating system completely crashed and my printer lost its entire configuration, forcing me to go through the entire printer re-calibration (~1 hour).

The suggested fix is, if a print is stopped mid-print, either don't move the print head so close to tool #1, or park the current tool before moving the tool changer in front of tool #1.  If the tool changer doesn't have a tool attached to it, then it won't crash into tool #1.
