Building an Arduino Controlled CNC L298p Help

Using Arduino Motors, Mechanics, Power and CNC
#1

I am a beginner, myself, with Arduino, CNC's. i am saw something on youtube and decided to tray to make it. But i have some problems vith arduino and shiled.. i tray to meke this https://www.youtube.com/watch?v=opZ9RgmOIpc

but with 3 ahis and if succeed ill make bigger

but i am ordered different shields

L298p dual h brige

and L293d like this

https://www.google.rs/search?q=l293d+motor+driver&client=firefox-b&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjE-Jfo6-zSAhWFlSwKHTFRDJ4Q_AUICCgB&biw=1280&bih=635#imgrc=SUOuDTbU6jY6rM:

and arduino uno

and i cant control third axis when i connect all shields and arduino 2 stepper motors move but the third connected in l298p want work only small speaker buzz all time but other 2 motors connected on l293d work normally . can any1 help me somehow i am new in this.

How is your question related to the way the Forum software works?

I am suggesting to the Moderator to move it to Project Guidance.

You need to post a link to the datasheet for the stepper motors you are using. More than likely those shields are quite unsuitable for your motors. But without details of the motors I cannot say more.

You need to explain more precisely what works and what does not.

Give details of how everything is connected in such a way that the differences are very clear.

And post the program that works and the program that does not - or identify the part of the program that is not working, if it is all one program.
