Arduino Mega Stepper Nema 17 Control With TB6600 Driver

Setup Instructions

Connect the Hardware:

• Connect the TB6600 driver to the Arduino Mega:
  • ENA- → Pin 4
  • ENA+ → 5V
  • DIR- → Pin 3
  • DIR+ → 5V
  • PUL- → Pin 2
  • PUL+ → 5V
• Connect the Nema 17 motor to the TB6600 driver (A+, A-, B+, B-).
• Supply a suitable power source to the TB6600 driver (VCC and GND).

Configure the TB6600 DIP Switches:

• Set the DIP switches on the TB6600 driver as follows:
  • S1 : OFF
  • S2 : OFF
  • S3 : ON
  • S4 : ON
  • S5 : ON
  • S6 : ON

Identifying Nema 17 Motor Coil Pairs (A+, A-, B+, B-)

• The Nema 17 motor has two independent coils, each with two ends (A+, A- and B+, B-).
• Measure the resistance between each pair of wires:
  • If the resistance between two wires is low (typically a few Ohms, e.g., 2-5Ω), those wires belong to the same coil (e.g., A+ and A-, or B+ and B-).
  • If there is no resistance (open circuit, infinite resistance), those wires belong to different coils.
