I decided I liked my Zonestar Z6F so I decided to give it the treatment.
TL Smoothers. Stepper Dampers. Ultraquiet Fans.
it now prints nicely and is nearly silent. but the stepper dampers lowers the Y axis stepper motor enough that the printer no longer sat level.
So in tinkercad I designed this little foot to "lift" the printer a few millimeters to alleviate the problem. you need 4. shrink a tiny bit for a friction fit or just glue them on like I did.
I printed with 4 perimeters 3 top 3 bottom 0% infill.
