The obvious question would be have you done a PID tune of the heaters yet. Do you see any noticeable swings in temps? Even though the temp is set the same the actual temp at the nozzle could vary significantly due to different drafts or positioning of the cooling fans.
There is very little straight forward about DIY 3D printing. That's what I love about it.

I have not done a PID test, tho' now I know that is something else to go on my list of things to do and I did not notice any temp swings. I have, however, found the root of most of the problem: loose as a goose Y belt. Not sure how it loosened up, but the sucker is tighty tight now!
