Help with Maker Select Mini prints

I have been printing on the maker select mini for about a month and a half now, and ever since it jammed one night it has been inconsistent with prints. Often in the middle of a print it will have trouble continously extruding, and I will get prints that look like these. Any idea of how to fix it? I have tried playing around with temperature and retraction, but no luck. Also yes these are parts for the Liberator which is perfectly legal to do where I live. http://ift.tt/2aS2Xfm

clicking noise from y-axis MP maker ultimate 3D

First of all, sorry my first post is asking for help. I’ve been interested in 3D printing for a while, and finally bought the new monoprice maker ultimate 3D. (rebranded wanhao duplicate 6 from what I hear.) anyways, I’ve been happily printing on it, but now I get this clicking noise from the y-axis whenever the extruder is anywhere near the middle of the bed. It is louder than it sounds in the video, and I think it’s getting worse!https://youtu.be/22B-m2vV8gQ http://ift.tt/2aKQGOL
