just fitted.

Can't see any obvious difference, they look smarter - but no change in wobble when you move the z-axis up and down.

Is there a specific way to level the gantry ?
I levelled with paper, then re-calibrated the bed.

I mean it looks level. but I have no actual way of telling.
Definitely need somethign at the top to keep the screws centred.
currently making a basic cable guide.
