This application note describes how to implement an exact linear
speed controller for stepper motors .
this circuit to control (3) stepper motor by parallel port
every motor will take 2 pin
pin(1) for enable
pin(2) for direction
mechanism of CNC
note: if we replace head with soleniod ,the mechanism will be more easyتفاصيل تصنيع الماكينة
parallel port consist of:
8 port output
4 port control
5 port input
8 ground
