How do I configure my control program (i.e. Mach3, EMC2, etc.) for lead screw steps per inch?

You will first need to derive the number of turns per inch that your lead screw produces. If there is only a single start (typical all thread screws), then the turns per inch is the same as TPI (threads per inch). If there is multiple starts, then the number of starts is divided by the TPI to determine the turns per inch. For example, 10 TPI with 5 starts is 10 / 5 = 2 turns per inch. Now that we know this, we can get the number of steps per inch as described in the previous question: take the number of steps per revolution that the motor will output. This will be the number of full steps that you motor produces (typically 200, or 1.8 degrees per step) multiplied by the microstepping per step to which the driver is configured. Simply multiple the number of turns per inch and the number of steps per revolution and you will get the steps per inch. Ok, lets see the formula: 200 steps * 16 microsteps * 2 turns per inch = 6400 steps per inch Additional Information: 14798 Additional Information: hallo i have cnc with ball screw 2.5mm of pith..n driver stepping 1/16 how to setup step value Additional Information: i have ball screw with 2.5 mm of pith n 1 start motor 200 step 1/16 driver stepping Additional Information:
