but problem of using DC motor is that it is difficulty to control number of rotation rather than step motor...(it needs additional circularity like printers having that rotating scales) so better option is step motor..idk whether it is possible to control step motor using above IC...and also i wanted to change motor direction once an IR sensor interrupt by paper....
The L293D will drive a stepper as i have used many of them, the chip is rated to 1 amp so the motor must not draw more than that.
Forward and reverse is just a matter of the code from the micro or computer to drive it.
It all depends on what pattern you drive the coils of the stepper in, to what direction the motor goes.
hello..anyone can give me good circularity diagram for 2-axis stepper motor controller with IR interrupt switches which uses to control direction of the motors..and it should be able to control via PC ports....
Yes..mate i saw that DIY CNC....but i hope someone can give me a ready to eat one ...lol...i mean without experiment...just simply made and WORKED..thank you...i'm still finding along your valuable clue.........
I have been there and built stepper drivers for use with CNC machines and would not bother doing it again, as you can buy the boards ready made off ebay for less than the parts will cost you.
This is what i used in the last small cnc router i built, and the boards work very well.
