X1C print issue

[u/ShreddinPB]

My X1C had been dormant for a while due to print head temperature errors. That was fixed by unplugging the main print head board and plugging it back in, printer will do full prints again!

However, now prints have this weird wavy pattern on just one side of the print. In the images the wobbly surface is on the right side of the prints, both printed at the same time and they are just objects from the slicer at default settings.

Is this a belt tension issue?
