You can display the slider under each post by pasting the following code in your Theme’s functions.php file. (Change slider ID as per your carousel ID)

function rpc_render_after_post_content() {    
    if( is_single() ) {
        echo do_shortcode( '[wcp-carousel id=1609]' );
    }
}
add_action( 'the_content', 'rpc_render_after_post_content' );

Please make sure to Disable Current Post from Advanced options, this way the current post will not be visible in the shortcode.
