so... have posted little stepper motors. gotten myself in hot water moderators behavior towards less friendly forum members 
subjective criticism welcome. questions or opinions too. negative sake of being negative need not apply.
here's project....
want use total of 5 stepper motors develop commercial product using raspberry pi3, motor controllers, drivers, , steppers. none of steppers run @ exact same time. 2 of steppers strictly rotation, , other 3 linear actuation. interface hmi, , sequence of steppers based on user input. of steppers run slowly. no need speed. turn in both directions based on user inputs. 1 of steppers high torque (1841 oz.in) nema 34 running @ 5 amps (14 lbs
). other steppers nema 23 running @ 2.8 amps. can proface lt , couple of i/o remotes. using pi challenge... 1 want overcome. hope able share successes , failures design mechanical , automation product. of project mechanical... automation sets apart existing products on market.
