Polishing the rods with 2500 grit and olive oil. Filed down the rough cut ends first. They're so much smoother now, like glass compared to the unpolished rod. Swapped the Arduino/RAMPS screws to M3 hex heads (3x20mm, 1x8mm,but I bought 10mm and it was good enough). Put the y-axis bearing holders back on the center but added washers to the bottom because I hate nuts on plastic without stress support. Just had the GT2 arrive so that will be started next until the new rod supports Mark is mailing me arrive.
