Needing Help With Egg Turner Project
March 25, 2016 10:43PM
Hello,
I am trying to build an automatic egg turner for my incubator. I have a powermax stepper motor model # P21NRXA-LNF-NS-02. I am needing to know what all I will need to make this work. What kind of controller or etc to make it turn x amount of steps one way then that x amount of steps to tilt the egg tray at certain times. I also need to know how to code for this or how much somebody would charge me to write some code for this project. I am new to stepper motors and controllers so dont bash me to bad..lol .. Any help witt his woud be appreciated.

Stepper motors are easy

Use pololu drivers [www.pololu.com]

Only 3 lines to control enable, step and directions

See ramps test code for a simple eg on how to move them [reprap.org]

The pins are for a ramps board, but just change the pins to match what ever you use as a controller

The main issue is you will need some way to set zero position, as steppers do not know where they are on power on.

NB the steppers you have need to much current for full torque, pololu steppers are only really good for 1.7 amps, your steppers are 2.8amp
cant find the voltage..... or the torque specs
