[Parts knocked over]

PLA and PETG. It does it with both materials. I releveled the plate and it still does it at different points of the part.

Thanks for your response, Klaus

[Parts knocked over]

All my parts that I print on my Ultimaker S5 are being knock over. I tried different material and both print heads. At the same time the print nozzle's spit out small pieces of material onto the plate. This started about a month ago. Possibly after I installed Ulitmaker 6.1.1.    Any suggestions?   Thank you,  Klaus
