Tacx NEO 2 SE - Cassette installation failure

Hello all
I have recently purchased a Tacx Neo 2 SE smart trainer
Along with my trainer, I have also purchased the same cassette I am using with my bike, Shimano 105 CS-R7000 11-30

According to instructions, I do not need any spacers. However after trying very hard and failing to prevent wobbling (and yes, I have applied sufficient level of force), I went to a bike shop and they have installed the cassette by removing one of the rings from the cassette & by including a spacer (Spacer belongs to bike shop, spacers that came with Tacx Neo 2 are very small in diameter and they dont fit on the freehub)

However, after some time I realized the cassette started wobbling. So I thought the cassette should have an issue and I might have messed it up while applying force with the torque wrench. So I purchased a new cassette and tried installing again, however it is the same issue, cassette is wobbling.

In summary, how do i install this cassette: www.bike-discount.de/.../shimano-105-cs-r7000-11-speed-cassette

to this trainer: www.bike-discount.de/.../tacx-t2850-neo-2-smart-trainer

And again, I have not received any spacer that would
fit on the T2875 freehub that comes with the trainer itself.

I highly appreciate your support. I probably worried more about the wobbling than enjoying the trainer in the last 2 months. Right now I am just so frustrated with so little instruction on user manual and I do not trust any bike shops in Berlin which can accurately install this cassette (by not doing stupid stuff like removing one of the rings from an 11 ring cassette)

Hello,
I bought the same equipment with the same problem as the ones presented here. Have you found a solution?
Thanks in advance for your feedback

hello!

I bought a proper torque wrench to make sure I apply force at a reasonable level and at the right angle. That somehow fixed the issue. I also have the spacer in place right at the beginning, before installing any piece of the cassette.

Knowing what I know now, I probably would purchase a better cassette because as far as i understand, this is also not the quietest one, which is kind of a waste after paying so much for NEO2

I have this same issue, I’m going to try and put a spacer on the chainring crank, thus moving the cain rings slightly over to the right, when viewed from behind. My reason for doing this is I’ve noticed the chain catching the largest chain ring and clanging occasionally when riding in the smallest cassette gear / small chain ring, if that makes sense!! I feel that the issue might be being caused due to the chain alignment with the chain ring at the bottom, so when the chain leaves the cassette it is not aligning properly with the chain ring, causing the chain to vibrate, Has anyone tried this?
