I am currently trying to build a 3D printer for a senior design project. I am attempting to connect a Nema 17 stepper motor z-axis (https://www.banggood.com/CNC-Z-Axis-Sli … rehouse=CN), to a raspberry pi 3 (https://www.amazon.com/dp/B01C6Q2GSY/re … rd_w=wIfhE) using a RPi motor hat (https://www.digikey.com/products/en?mpart=2348&v=1528). I am new to this and was wondering if anyone could tell me how I could set up these components to command the z-axis nema 17 stepper motor using nanodlp?
How do I figure out which GPIOs correspond to what on the hat if I am trying to manually set up each pin for the axis?
Thanks!

Hey thanks for your input but that didn't help. We still can't figure out how to control the z-axis. Are we supposed to set up movement GPIOs manually through nanodlp?

When you have installed Nano DLP you import a machine profile.
Go to this page https://www.nanodlp.com/repo/ and 3rd from the top is "Nano DLP generic" - "Direct control" machine profile
Then looking at the schematic > https://www.nanodlp.com/download/schematic.png
@B1 ( schematic grid) is the GPIO schematic for the Raspi. From this you can read off which GPIO pins are used.
Example > for the stepper driver
EN = GPIO 15
DIR = GPIO 16
STEP = GPIO 22
You will basically need to replicate ALL the circuitry and components shown in the schematic, onto your Raspi hat.

This one is suitable for 3d printer:
