I suspect I did things wrong based on your excellent write-up.
I got the (new) anti-vibration feet with my X1C less than a month ago. I noticed that when I placed the AMS on top they get REALLY squished down. In fact, if you move the printer around and aren’t paying attention the feet will squish diagonally which is not good IMHO.
I then went out and got a 16"x16" paver and put on top of some foam used for packing some random Black Friday equipment purchase. Then I set the printer on top of that with the anti-vibration feet. I suspect this was bad because you said: “Do not put isolation pads/feet between the printer and the pavers.”
Every time I make a change I run a full calibration, but on a recent tall PETG print I saw vertical lines form and continue to get “worse” the taller the print went. I’m 99.9% sure these are vibration related. I ran another full calibration after that and a similar print didn’t seem nearly as bad, so I find it odd I have to run the calibration multiple times.
So, to confirm my suspicion - I should not be using the anti-vibration feet in between the printer and the paver stone, correct?
I’m also curious if anyone else has any thoughts on the use of the anti-vibration feet w/ the AMS on top of the printer - independent of the use of a paver stone w/ padding or not. I swear I read somewhere not to do that (someone even said the AMS was never meant to go on top of the printer being shown that way non-stop in marketing materials).
Again, thank you for a really great write up. It’s nice to have somewhere to go to reality check what I am trying to do with my likely overthought implementation.
