Hi I want to use cnc shield v3 directly with arduino ide directly not with GRBL. My question is what are the pins that control the stepper motors and what are the pins that control the limit switchs ? I am using arduino uno.

What did you discover when you searched for "arduino cnc shield v3 schematic"?

it's not a schematic, it's a pinout. You need a schematic, which will show how the elements are connected to each other and to which pins they are attached

Have a look here: OSOYOO Basic board + CNC Shield V3.0+A4988 Installation Guide « osoyoo.com There is a schematic for the board. There's also this handy image: [cnc_shield_v3_3] And a lot of other information.

That applies to UNO and works well. I'm using it in CNC based a MF70.
