edge and infill issues after fixing x motor

[kwatts 0]

Hey,

So I have been printing pretty good for a few weeks.

The other night I found during a 2 hour print that I could hear a clicking and grinding sound. Yay.

The grinding was coming from the xmotor its band was rubbing on the wood frame when the head traveled from left to right. I realigned the drive gear on the motor and the one on the x rod. Then I relised that the y back rod was causing the clicking. It was traveling 1~1.5mm from left to right on fast moves.

Im not sure how I fixed this, but it has stopped.

Now I get some prints with gaps between the border and the infin as well as really crappy bottom layers.

What do i start to look at to fix this?

Im using cura rc4 and i have not modifed any of the settings between the prints.
