DC Worm Gear Motor 4 Jaw 80mm 4th +Tailstock CNC Dividing Head Rotation/A Kit for Mini CNC Router/Engraver Wood Working Engraving

1 pc -- 4th 80mm 4 Jaw Chuck ( Positive jaw and counter jaw ) 1 pc -- Tailstock 80MM four jaw self-centering chuck Center Height 65mm Total height, 115MM Angle, 0.3 degree/step Reduction ratio:6:1 (synchronous deceleration mode) Magnetic stepping motor: Two-phase 57 step motor Four-wire The system settings: the pulses for 1 required: ( the motor 1 Circle of pulse number × the drive of subdivision number × reduction ratio) ÷ 360 degrees For example, the two-phase 57 motor, the ubdivision number 16, the reduction ratio 50:1 (200 × 16 × 50) ÷ 360 = 444.44444444) Ncstudio system settings: the angle of a pulse walking: 360 ÷ (the motor 1 Circle of pulse numberr × × the drive of subdivision number × reduction ratio) For example: the two-phase 57 motor, the breakdown of the number 16, reduction ratio 50:1 360 ÷ (200 × 16 × 50) = 0.00225 X or Y instead of the algorithm is: Circumference ÷ (the motor 1 Circle of pulse numberr × × the drive of subdivision number × reduction ratio) Engraving different sizes of round bars, equivalent needs to be set.
