Very cool. What units does the A axis use? Degrees? Radians? Mm? If mm, how does it account for different diameter stock?
It’s degrees. The feedrate is degrees/minute. Later in the video you see me play with those settings. BTW, this 4th axis has a 3:1 ratio. Each 360deg rotation of the stepper = 1/3 rotation of the part due to that timing belt ratio.
Ah. Ok. You haven’t adjusted your steps per unit yet, I guess. The movement of 100 only seemed to go around 30°
very cool John!
