Stepper motor control help needed

Evening all,

its been a while since I last ventured into the world of Arduino so I'm looking for some help.

I am using the following code to control a stepper motor via mqtt. What I want to do is control 2 motors individually from the same sketch and add the option of controlling the motors from physical buttons. I will be running this from a nodemcu i think.

Any guidance will be greatly received.
