When I rapid in the Y direction I lose steps, like a lot, usually in the middle area of the screw. No issues at any other speeds. What are possible causes?
I found when my gantry is not very square with the y rails it can skip steps because it puts unnecessary force on it. This wouldn’t explain why it only happens in the middle though…

Welcome to the club :)……make sure your gantry is square first and then re-adjust your limit switches. I used 2 electronic tester on continuity setting to nail the moment when both limit switches turn off.
This should work even though I suspect The stepper drivers for Y are at the limit when on rapid move.

Also, make sure no chips got behind the limit switch levers. Had that happen twice already.
