Trying to do a basic print with my UM3E after the update to the latest firmware 5.2 I believe. Not sure if it is a coincidence, but every time I print the nozzle is virtually scraping the plate. I have tried autoleveling a few times with no errors and get the same result. I have manually leveled with the same result. I even tried manually leveling and purposefully putting the nozzle high (over a mm) and it still scrapes. Is that a software issue? Potentially a sensor issue?
