Rub it in why don't ya!!! I'd rather be boating than shoveling.

LOL that was kind of my thought as well - except not exactly shoveling here... supposed to be in the 40's for the next week or so

I may try that print later - have to go cut grass now.  A lot of you are shoveling snow - we're cutting grass - it's 72 here and its not noon yet!

Bearings seem OK.  Visually, everything looks OK. Just recently re-lubed all the shafts with a rag dampened with 3 in 1, same stuff I've used for 2 years. 

Back after a few.

I wonder if I let it go, how far it would have rotated?  smile

I agree with wardjr as well.

As an added note, by looking at your first pic and your signature, you have linear bearings and are over extruding. In the first image, the is not only a shift with blobbing, but there also seems to be a twisting pattern when viewed from the top.
You may want to confirm your bearings have not popped out of place (looks to be) on one side. This is easy to confirm, and fairly easy to fix.

or something is snagging carriage while printing like filament on fan or something or lube is drying out/dirty after lots of use.

Looks like some heavy over extrusion.  Probably should recalibrate for that roll.

Even the same color form the same vendor will be different and requires you to calibrate each roll change..

Side view.  The whole works is twisting CCW
In the front view, everything appears square... WTF has gone out of whack now?
