Circuito CNC-Arduino:
Terminal azul - El que esta al lado de los tips:
pos 1: motor (verde)
pos 2: motor (rojo)
pos 3: motor (blanco verde)
pos 4: motor (blanco rojo)
Terminal azul - El que esta debajo del de arriba:
pos 1: arduino (digital 7)
pos 2: arduino (digital 6)
pos 3: arduino (digital 5)
pos 4: arduino (digital 4)
los dos common del motor (cables blanco y negro) van a +

Mach3: explicación de step y dir:
The standard signalling for hobby CNC axes is know as STEP/DIR. Two lines, one indicating direction (High/Low=Fwd/Rev), and the second is pulsed (Low to High to Low) to indicate a single step.
Motores:
ASTROSYN - MINIANGLE STEPPER
TYPE: 23LM - C343 - P2H
3.5 v/PHASE
1.4 amp/PHASE
1.8 deg/STEP
NO. T0615
MINEBEA CO., LTD. 782-22
Cableado:
common (+12v) = rojo+negro
secuencia=blanco_rojo, blanco_verde, rojo, verde
-------------------------------------------------------------------------------------------------------
Como calcular los amperes necesarios para un motor:
P = V x I
Si el motor es de 180Watts y la alimentacion es 24V, los amp que requiere son 180/24 = 5amp

tip102. visto de frente: pata izq=base, pata medio=colector, pata der=emisor ***LA PLACA METALICA ES COLECTOR***
Ventilador:
base -> 10k -> +5v
colector -> negativo del ventilador
emisor -> -12v
positivo del ventioador -> +12v
Stepper:
negro y blanco del stepper -> +12v
base -> 1.5k -> digital pin 11 de arduino
colector -> blanco_rojo del stepper
emisor -> tierra
base -> 1.5k -> digital pin 10 de arduino
colector -> blanco_verde del stepper
emisor -> tierra
base -> 1.5k -> digital pin 9 de arduino
colector -> rojo del stepper
emisor -> tierra
base -> 1.5k -> digital pin 8 de arduino
colector -> verde del stepper
emisor -> tierra
gnd de arduino -> tierra ***todas las tierras juntas, como siempre!!***
Codigo del arduino:
int motorPin1 = 8;
