After print finishes pressing [+] on bed moves it up instead of down.
First time I stopped the print and wanted to lower the bed so I could remove unfinished print. Pressing [+] moved the bed up resulting in hot end smashing into the print, deforming bed and finally getting free when I managed to move the head to the side. This deformed rods a bit, but luckily seems that it did not affect the printing quality.
