How to Directly Drive x.27 or x.40 Stepper Motors

For this tutorial, you need the following components

• MobiFlight Connector
• MobiFlight Compatible Arduino with the newest MobiFlight Firmware
• x27 Stepper (Singleshaft) and/or x40 (DoubleShaft) Stepper
• Soldering Iron, Soldering tin, wires

Connect the wires to consecutive pins in your Arduino:

Go to "MobiFlight Modules"

Add a new device (Stepper Motor), then configure the pins, so that Pin 2 and Pin 3 are swapped:

It is important to have these two pins swapped otherwise the stepper will just buzz around angrily.

Under "Output" create a row, and name it what you'd like. Don't forget to check the active box.

Configure the stepper to whatever you'd like.

Under display, choose your stepper and insert your sim/stepper value. For me I found moving the stepper 729 steps gives 360 degrees of motion. The stepper has 315 degrees maximum so I set this as the test value.
