Power on A and B coils, use 66% current drive to reduce heating when half step drive.
You are advised to use 100% current drive during speeding up to increase power.
1.1 stepper motor drive
1, Use PWM way to advoid motor over heating. you can choose chips: L6219,L2916,L3967 or others;
2, motor should move 24 steps at least to avoid the color bar destroy when printing as the color bar is also drive by printer head.
3, the motor drive should be finished according to HOME place detection. When it is in HOME, the step motor allowed to move 27 steps toward the right, 228 steps toward to left.
4, the motor drive should be slow stared and stopped.
