This code should activate all the steppers, fans, and heaters. The only problem with this code is that it does not activate both z-axis steppers; it only activates one. If you encounter any problems with any of the components, try isolating them and only running them in the code. If you would like to test the z-axis and thermistor, download the following codes:
