### Question #: 3626

Question:
**
how much would a 6 foot 5 start lead screw cost?
**

**
**

**The price of the 1/2" 5 start lead screw can be found here (units are in inches):
https://buildyourcnc.com/item/mechanical-leadscrews-lead-screw-!5-5-starts-10-tpi
I did not include the price for this answer since the price may change from time to time.
For 6 feet of lead screw, the number of inches is 72, so simple multiple the price by 72.**

Does the 5 start lead screw come with any nuts?**should all three lead screws be a 5 start?**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.

A screw at that diameter is is not the best solution at long lengths for machines that will spin that axis quickly since there will be screw whipping.

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.**Click the link to respond:**

I will need to add up the cost. However, the complete kit with the wood components will cost in the range of $300 to $500 using freight.

Additional Information:

I will add a price option on the Vertical Laser XL page that shows the assembly price without the wood structural parts. Are you wanting the rails included in the price?

Additional Information:

Hi, I was expecting an email answer, I did not know that you answered. Also I am in Fiji, not Canada. There is a flaw with your question form, It would not accept Fiji because we have no postal codes, so I put in my old Canadian code so that it would accept my question.

Yes we would need the rails and any mechanical and electrical components. Our plan is to build it against a wall in a shipping container.

If you do not have a suitable freight forwarder I can ask at this end because people frequently receive shipping containers.

Thank you,

The lead screw should turn, but not move any other way. The method to keep the lead screw stable is to use two bearings with ID (inside diameter) that match the diameter of the lead screw. The bearings are positioned before and after a stable structural part. A collar is positioned at one side of the bearing assembly and another collar, or end of a coupling is positioned at the other side of the bearing assembly.

HOW MUCH MOTOR CABLE DO I NEED FOR A BLACKFOOT**how do you calibrate steps per inch using Mach3 and a 1/2x13 lead screw**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
