• sc21, 2000deg/s
• sc22, 2200deg/s (higher velo than this vibration starts)
• sc23, 3000deg/s works but much vibrations..probably loosing steps

• sc24, 720 deg/s
• sc25, 1720
• sc26, 0.1
• sc27 2000, works nice, current looks a bit strange
• sc28 2200, works nice, current looks a bit strange
• sc29, 3000 OSC alot, loses steps
