I own a JAurora A5 and have your astroprint software installed on my raspberry pi. I have been using it for about 1 week and it has been excellent.
The only problems I’m currently having is during levelling my printer it would sometimes freeze in midair while astroprint is connected and it works just fine disconnected.
My second issue is that on my PC I can not login on the Password Screen but when test on Mobile it works just fine on the Web Interface not the Cloud.
