I am getting very disappointed by the UM2+ performance after the Cura Upgrade.
While it was working well with the last version (3.1) + firmware on my MAC, since the 'upgrade' the system has been misbehaving badly.
Apart from the pimple at completion, I can now only get fairly decent prints with a feedrates of 200-250%(!).
Have tried almost everything: factory reset, new PLA, new nozzle etc. It just isn't the nice (but expensive) machine I bought and used over the past 2 months.
I won't buy this machine ever again if this does not get fixed.......
