Hi Zhekka77! I got the same problem with my Adventurer 4 printer. Unfortunately I have no Idea about the Issue and no solution eather. The only thing I imagine was, the failure happens after printing models one after the other. Maybe it will help to move the Bed and the Nozzle back to Home Position after each Print Job. Do you or the community have other experiences or solutions ? Please let me/us know. I`m using Autodesk Fusion 360 for modeling and FlashPrint 5 to slice and send to the Printer via WiFi. All the software is up to date!Greatings from Bavaria( hoping my English is god enough )
