to me it looks a combination of things speed and extruding too much material, make sure your extruding the correct length of material, speed i started slow at external and internal at parameters set at 28.5 mm/s but i have wacked my feed rate up by 100% i know i can do 57 mm/s but check that your extruding the correct length and slow it down if its fast

If you have a heated bed you need to level it when it's at temperature and check level when it's at temperature.
It's no good doing it when it's cold heat makes things expand.

Check for any binds in the z-axis what kind of motor couplers do you have if you have just the tubing it's probably getting loose buy aluminum couplers

One other thing to check is make sure the z-axis is very free it has to lower itself by gravity alone if you take the threaded rods out. The reason for this is there is always play in the nuts and screws you want gravity pull it down the on the screws and nuts if there's the slightest bind holding it up would be to the top of the play in the nuts one time and then the bottom of the play in the nuts next

On the couplers you have to find something that will fit in there loosely so the screw and the motor shaft touch otherwise coupler is going to act like a spring. Can be a ball bearing and something else could be two ball bearings

Yes motor shaft and threaded Rod should be touching inside couple which allows side to side movement but not down. If you don't have this to push on the X axis you'll see the couplers compress like a spring not a good idea
