Find Right stepper motor for CNC

Post by fentigkou32 » Wed Mar 11, 2020 9:46 am

Hi all,

It's about time I got out of the dark ages when it comes to drilling my boards and I wish to build a CNC machine. While I understand how the drill info is sent to the machine which steps motors to get to the right place I am unsure about which motor to go.

Just about in every project I have seen the large square stepper motors but I saw these:

https://www.oyostepper.com/goods-73-Nem ... Wires.html
Are these acceptable for a small light weight machine? I know that torque might be an issue which is why I would make the axis and table as light weight as possible. Could these be used?

All the best,
Robin

Those will work but the small engraver machine usually use Nema 17 steppers. The are a size down from the Nema 23 you are looking at...
