arduino based cnc plotter machine

I am shubham shinganapure an electronics engineering student I made this project Arduino based cnc plotter machine using Arduino cnc shield and A4988 stepper motor driver module which are commonly avilable in market. now I want to rebuild this project by usng l293d H-Bridge motor driver ic for that I design A simple cnc shield using l293d ic. here is cad view of shield.

I am using small stepper motor to drive x and y axis and a microservo motor to control up and down movement of pen. 

I am thanking to PCBWay to create this oportunity for maker like me to make our dream projects in real life,by using pcb fabrication services from pcbway we get professional look to our project pcb.
