I will double check the firmware and make sure I am up to date (I know Cura is the latest version). I do not have any issues with the other colors I have, just the blue, so I am not sure I have a feeder issue on the printer.
I have played around with different temp settings and speeds with no success. I followed the troubleshooting guide on the site for under extrusion. I do not have this issue with the other colors I have (all from Ultimaker), just the blue.
I am looking to order some more PLA and try some ABS, but I want to figure this out first. I know there are a lot of variances in diameter with plastic from different providers, and want to make sure I can find a good quality plastic I don't have to reconfigure the machine for if I want to use.
