Hi!
I’m not sure what firmware version you are using, but there has recently been a semi-large firmware controversy. Version 1.08.00 seems to be messing up some people’s printers. This is fixable though.
Assuming you are using 1.08.00, I recommend downgrading to 1.07.00.
(The source post is linked, as is a video link on how to downgrade)
In this video, he only downgrades one version, but everything else I see says to downgrade to 1.07.00.
