I have a similar weekend! Adding an aluminum extruder and this coupler for the lead screw:

The first photo shows the orientation on the bed. If you look, you can see lines at the bottom of the print, but they aren't too bad, if at all as the print goes up.
This is on a Tevo Tarantula on which I have relocated the z-axis motor to the bottom and I am using this coupler - https://www.amazon.com/Befenybay-Aluminium-Flexible-Coupling-Connector/dp/B07RMZCLZ3. I am running this oldham coupler - https://www.thingiverse.com/thing:2568712. I am wondering if the coupler is causing more wobble at the bottom than the oldham can compensate for but as it goes up, the oldham is better able to compensate?
Any help will be appreciated.
