I unchecked the spindle speed averaging and it works without modifying the speed per pass which is good, still doesn't account for speed yet. I haven't adjusted the speed file however I will be changing the pulley on the motor, I have like a 12 inch pulley on it, I'm going to put a 4 inch on so I have more torque and speed response. It's very slow to speed up and down without tripping the drive... lol
