Compensate for ImprovementsI don't want to say my Ubis hotend was bad but I usually had to have the hotend set at 200˚ or I would get pretty consistent clogs and failures. When I first got the Printrbot I was able to print around 190˚ and when it got cranky I'd had to print at 220˚. I usually had to set my flow to around 85% on the Ubis to get good measurements at 200˚ but that needs adjustment as well. With your new hotend you'll want to dial in your settings again. Find the perfect settings.
For me I was able to transition down to 185˚ for most prints with a little tweaking for the first layer to get optimal bed adhesion. I'm still working things out, but the temperatures I want for optimal printing will be a little easier to hone in on.
You can also speed up your print quite a bit. Of course the final speed you'll want to use will depend on how complicated your print is and how your filament reacts at certain temperatures, but I moved my minimum print speed to 60mm/s without issue.
