Hi Kasper
I will also try this new rod/kit as soon as it’s available.
My Z axis wobble is not really bad, approx. 0.07mm (hard to measure) and much better than the original 1.1mm I had with the Velleman parts, after I fitted a new motor mount and a flex coupler.
However, I think it could (should) be even better with a “proper” spindle (I’m still using the original M8 rod).
Currently the weight of the Z axis is supported by the top bearing and I don’t feel comfortable placing the weight on a flexible element.
I also don’t quite like the way the K8204 Z axis follower is mounted. I will create some kind of plate between the follower and the Z axis mount.
