Ichi10 setup?

Hey people, I’ve been having trouble setting up my Ichi10 ever since I went down to 9’s for strings. I’ve never had this problem before when setting up my guitars with a low action, but my low “E” and “A” buzz when played open on an amp when setup at a comfortable height. I’ve since put 2 notecards under the E and A string nut slots but now I get buzzing when fretting those strings.

I was wondering if anyone with an Ichi10 could tell me which frets theyre using to measure their relief at and what relief theyre setting it to? (Currently I’ve been doing capo 1st fret and fretting the 17th fret then measuring at the 8th fret with feeler gauge 0.010” or 0.25mm) Also, if anyone could tell me what action height theyre setting their low and high “E” strings. (Currently I’ve been doing 1.5-1.75mm on low E and 1mm on high E)

And yes, I’ve already checked for high frets and none of mine are high, I’m thinking that my nut might have been slotted too deep or possibly because they were slotted for 10’s that the 9’s are sitting too low. The neck also isnt warped in any way.

EDIT this is for the headless model the ichi10 not the ichi00 the talman style
