Steppers can also be driven at different step ratios. Common lead screw ratio calculations: Inch Steps Per Lead Screw Inch Metric Steps Per Lead Screw mm Stepper motors are usually 200 steps per rev, and sometimes 400. The precise ratio is and calculates to steps per rev. If the motor is mounted on a 10 pitch lead screw, then the linear motion ratio is 10 * 5600 or 56,000 steps per inch. The 2.8:1 ratio calculates to around 2.8 * 2000 = 5600 counts per rev of the output shaft. With quadrature, the motor produces 2000 counts per revolution.

In the case of the IMService servo drivers with Globe motors, the belt reduction is setup so that one revolution of the output shaft is about 2.8 revolutions of the motor shaft. The Axis ratios are used in the DeskCNC machine setup. Copyright IMService 2005 Дў 1) Determine the steps to linear motion ratios for each axis. If the setup steps are followed in sequence, the machine setup dialog can be opened once and the changes all saved at one time, rather than after modifying each tab of the machine setup dialogs. 3 3) Setting up the software Machine Tab 4 4) Setting up the software DeskCNC Setup Tab 5 5) Setting up the software Axis Setup Tab 6 6) Setting up the software Machine Velocities Tab 7 Throughout this manual, each page is written to be a standalone operation. 1 1) Determine the steps to linear motion ratios for each axis.
