Check the guide rollers are not too tight, and there is no 'bump' you can feel when you move the axis by hand. Check all axis including bed. You will probably need to adjust them.
Mine came with bumps due to overtightened. Use the off center adjuster wheels to loosen them up until the axis moves without a bump. It should move freely but have no wobble or play. The adjuster rollers are the ones where the standoff the roller is on is not round. It is shaped so you can turn it with your spanner to adjust.
Looks like Z axis rollers, but I would check them all.
Best way is to slacken them off until there is wobble and play, then slowly adjust until there is no wobble or play. If you grab the rollers with two fingers, you should be just able to turn them while preventing the axis from moving. This should require only thumb and first finger, but should not be easy to turn.
You should feel the bumps have vanished as soon as the rollers are adjusted and the axis has been moved around a couple of times.
There are quite a few youtube vids you can find about adjusting the rollers if you are not sure about anything.
