Topic: I need Calibration help.

Hey all, I know it's been covered so if someone could just point me in the right direction I'd appreciate it.

My extruder lifts/tilts backwards at certain points along the x axis. It seems to only happen when it's towards the back of the printer. Just right of the back left corner is most noticeable. It almost seems like its the wires that press against the chassis but when I mess with them they don't seem to move it as freely so, I'm thinking that may not be it. 

I'm open to suggestions. Any input is appreciated. Thanks in advance.

I read something similar to this before, I think this might be a poke in the right direction:

Re: I need Calibration help.

I adapted this thing to solve that problem for me.

By spring loading the carriage, it takes more force to make it rock and things print much smoother in the back of the print bed.

Re: I need Calibration help.

Thanks a bunch guys. I do think you sent me in the right direction. It would seem that it is the wires that are pushing the head. I'll post an update when I have the issue resolved.
