Node-RED Stepper Guidance

I have a Raspberry Pi already running Node-RED and a bipolar stepper motor that will drive a small automated system. I now need clear, hands-on tutoring so I fully understand how to make the motor move from inside Node-RED.

Here is what I want from our sessions:
• Confirm the correct wiring to a suitable driver board and explain any power or safety considerations.
• Walk me through installing any required contrib-nodes or custom JavaScript function nodes for precise step control.
• Build a simple dashboard in Node-RED where I can enter step counts, direction, speed, and see live status.
• Add basic automation logic—start/stop buttons, limit-switch handling, and an example timed sequence—so I can use the motor reliably in my automated setup.
• Provide the final, commented flow export and concise notes so I can reproduce everything after the call.

We can screen-share (Zoom, TeamViewer, or your preferred tool), and I’m comfortable following along in real time. When we finish, the motor should rotate forward and back at adjustable speeds, stop safely on command, and I should feel confident modifying the flow on my own.
