Hot End BB pops fan door open on first layer during lift switch operation

Ultimaker 3_ SN  BPP-017174-060274

When the printer changes from AA extruder to BB extruder it causes a crash and jump on the hot bed.

The extruder/fan door pops open and seems to be too low on the bed.


I have downloaded the latest firmware.

Removed and reinstalled the extruders, cleaned the rods and feeders.

Cleaned the nozzles.

Done active and manual bed leveling over and over.

Reset printer.

XY Offset done
