EFW Filter Wheel Alignment Issue

Post by Blaze » Wed May 15, 2019 8:30 pm

Hello,
I'm using brand new EFW (7 positions, 36 mm unmounted) for few months and from the beginning encountered an issue with poor filter alignment accuracy. Took me a while to understand why lights not calibrated properly.
The issue explained exactly in following threads:

viewtopic.php?f=8&t=9862
viewtopic.php?f=8&t=7955

Tried to open the wheel and tighten all screws as advised in first thread - issue still exists.
Tried to perform init using 'Tool' utility as advised in second thread - issue still exists.

Attaching L channel master flat and calibrated light that demonstrates the issue.
Other filters suffering from same alignment accuracy issues.

Please advise.
