I have had my prusia i3 since the summer and I am just now getting it tuned in but my prints are taller on the z axis than they are supposed to be. I printed a 5mm test print and each square is supposed to be 5mm x 5mm but it’s roughly 5mmx5mmx7mm and it seems to be getting worse as the print gets taller. Also I have a wavy ripples one the side of my prints. Any help or ideas would be greatly appreciated.

What temps and speeds?

It look overextruded and could be to hot. Also see if belts or pulleys and loose.

Check your firmware or reload it. You might have the z steps per mm set incorrectly.

I fixed the z axis problem by adjusting the z axis steps. My extruder is set at 240° and the bed is at 70° I am using matchbox abs but it does the samething with pla. Even if I adjust my temp the wavy pattern persist.
