After completing my trim and sanding the edges I have been able to get every voltage resistance apart from 3v3 close to/higher than what it should be.
My 3v3 resistances range from 1.4k to 1.7k depending on which voltage pair I probe.
Is this fine? Should I continue sanding with 600+ sandpaper?

EDIT: Managed to get everything to the desired values by sanding up to 1200 grit sandpaper except for 3v3/1v15. Any advice on where I could focus on sanding because I just cant seem to get that pairs resistance to go above 1.5k.
