EFW 7 - Washer Spacing

Can anyone confirm that they need 1mm spacing between ASI1600MM and EFW7 to avoid 36mm filter screws affecting smooth rotation?

Also, I appear to need 1mm spacing (2×0.5mm washers) to align camera on EFW correctly.

Comments and experiences appreciated.

yes, spacer needed to align 1600 and EFW as they are screwed together

that's why there comes spacer with 1600
