First build, need help tweaking settings

Hello,

After finishing the build, and printing a bit with my new MK3, I've noticed a some lines appearing on my prints. They appear on all outer walls (not the top and bottom), and appear to repeat with a some relative frequency. Does anyone know what the problem might be? (pictures attached).

Also, even though the printer calibrates successfully, I notice that the right side of the bed lower than the left (if I move the print head from left to right across the X axis, there's more space as it progresses to the right, perhaps about a millimeter difference). Does anyone know a likely cause/solution for this? I've checked that the bed screws are equal tightness - what else could it be?

Thanks in advance for all the help!

Re: First build, need help tweaking settings

first thing to check would be if the pulleys are firmly attached to the shafts of the stepper motors (x- and y-axis)

Thanks!

The pulleys seem tight. I did notice just now that the X-belt has a bit of a tilt to it as the extruder moves (one side of the belt tilts down/up in the Z direction). I assume this could be a problem? What's the likely fix, and do I need to fully dissassemble the extruder to be able to adjust the belt?

Here's a link to observe the slight skew. Belt status reports X - 270, Y - 265. Thanks for all the help!
