Hello, I bought my UM3 around a year ago. For the last 2-3 months a am facing the same problem over and over again.
At the beginning everything was perfect. But as i said around 2-3 months ago the PVA(I use the ultimaker's one in BB core and PLA in core AA). It's like the PVA isn't sticking to the PLA.
Is there any fix or?
Best regards,
Bogdan
