The need for Speed

The need for Speed

Postby vcipriani » Sat Jan 17, 2015 6:12 pm

I purchased a 2' x 4' scratch and build plans/Kit from the build your cnc website about 2 years ago. It is going great and I am making several things with the machine. I have one question. I purchased the lead screw for the X, Y, and Z axis on my cnc machine. At that time the technical support recommended the 1/2" X 13 TPI. I then recently noticed that on the build your cnc website there was a new lead screw 1/2" x 10 TPI. Is there a big noticeable difference in speed between the 1/2" X 13 TPI and 1/2" x 10 TPI. Anyone's help is greatly appreciated.

Thx

Yes, because the 1/2" x 10TPI is a "5 start" screw, meaning that it is effectively 2TPI.
If you don’t have time to do it right, when will you have time to do it over?

Is any one else using 1/2-8 8 start? That really flys.
I just wish I could get 96" or 120" long pieces.
mmaster-carr sells it 99030A300 but you have to find nuts.
Dumpster CNC used to make them.
