Hello everyone, I need to control a few bipolar stepper motors (this http://www.motors.wrobots.com/EM-257_17PM-K212-PIT.php, salvaged from a printer) for an upcoming project.
After looking around for a bit i decided to go with the SN754410 but i realized two things : - on LadyAda's motor controller page they mention the following "the output diodes were designed for ESD protection only and that using them as kickback-protection is a hack and not guaranteed for performance." and they advise using a L293D instead. -ordering the L293Ds i need would be quite a bit more expensive
I am pretty much a complete beginner when it comes to motor drivers, and even after looking at the different specs i am still confused about which one to choose...: as this will be used in a diy CNC machine i would rather not risk burning the electronics out at a point?
Thanks in advance for any advice!
