After the printer finishes a Large Print or a tall print. the bed will be all the way down. When I start a new print with bed leveling, the bed will go down slightly and i think it crashes into the bottom. There is a loud motor noise. It could be a normal sound, but not sure
Yep this is a know issue. You have to manually raise the bed say 10-20mm before starting another print to avoid this at the moment. Thats the only work around i know
