This is my rough (pre-setup) guide before the strings are on. It is also the height of the nut slot above the fretboard (not above the first fret). It probably leaves the E quite close to 0.35 mm above the first fret.

They will need more precise filing with the final setup.

Ah, I see. Now that you explained your method, I get it.
Did you measure the actual height of the first fret before using the 1.7mm depth? Fret height will vary and you don't want to get caught short (or deep in this case! )

Yes I do check the height of the first fret. I'm sure I will get caught short one day though!

I find this technique really useful when I remove a nut and sand the base. I can do a quick check of the slot heights against a feeler gauge on the fretboard so I know when I'm getting close to the wanted height.
