Tachometer sensor

My oscilloscope shows a square-ish wave... the sides aren't perfectly vertical on the rising or falling edge. I'm seeing a steady 3.3v at rest, and it dips back to zero when the sensor sees a reflective surface.

Maybe my board is messed up? I feel like this shouldn't be this difficult.

Hello,
Did you make any headway on this issue ?
Thanks
Ben
