How do I configure the Flashcut CNC software for a Rack and Pinion or other drive mechanism?
Use the equation below to find the Screw Thread equivalent for your Rack and Pinion drive mechanism: Screw Thread = Rack teeth per unit length / Pinion Teeth For example, if you have a 20 tooth pinion and a rack with 5 teeth per inch, you would find your mechanisms screw thread to be 0.25 (screw rev/inch). In the Mechanics Settings portion of the Configuration Menu, enter the value that you found using the above equation for the Screw Thread field of that mechanism. If you have a gear train or pulley between the pinion and your drive motor, put the pulley ratio of this mechanism into the Gear Ratio field. For example, if your motor has a 10 tooth pulley that drives a 20 tooth pulley using a belt, the Gear Ratio would be 2 (motor rev/screw rev). For other types of drive mechanisms, enter the number of motor turns per unit length traveled by the axis.
