I have removed the bed wobble from luigi. If you were having issues with engraving and it coming out “fuzzy” then it should no longer be a issue
Could send send a note on how/what modification you performed to @FabLab ? It could be handy to know later.
I used masking tape around the slats.
You got to like a low-tech but effective solution
It works surprisingly well. I am thinking of ways to improve upon it but nothing yet
