If the turns per inch on a lead screw is different, then the nut on the lead screw will move at a different velocity.

Additional Information:
Let me explain in more detail.

Let's say you have two lead screws:

- 1/2" 5 starts at 10 TPI = 2 turns per inch. (5 starts / 10 TPI = 1/2 inches per turn or 10 TPI / 5 Starts = 2 turns per inch.)

- 3/8" 2 starts at 10 TPI = 5 turns per inch. (2 starts / 10 TPI = 1/5 inches per turn or 10 TPI / 2 starts = 5 turns per inch.)


So, if two stepper motors (one connected to the 1/2" lead screw and the other connected to the 3/8" lead screw) turned 10 revolutions in 2 seconds, the 1/2" lead nut would travel 5 inches and the 3/8" lead nut would travel 2 inches at the 2 second mark.

Hi! can i order a 6 ft long 1/2'' Lead screw?

The precision and number of starts for a lead screw will depend on the application. Having an ACME lead screw with 5 starts is a good balance for many applications so the machine will travel quickly along the axes with motors that hold best torque at low RPM. All three axes would benefit from 5 start lead screw for general applications.

The length of time it will take to build a CNC machine kit is not an easy answer. There may be a wide array of circumstances that limit a persons abilities to build the cnc machine kit in an efficient timeframe; however, if you have moderate dexterity and moderately mechanically inclined, you should have no problem building one of our machines within one weekend if the project has very little downtime.
