Im trying to make 2 axis cnc drawing machine but motors is only moving very little steps (0,05mm) instead of 4cmx4cm scale when code is running. im using cd drive stepper motors like this project ->

"arduino" is chinese copy ATmega328P CH340G UNO R3 Board :

and motorshield is chinese copy of adafruit motorshield v.1. It is h-bridge l293d. :

I have uploaded (with arduino ide) code that "teach" arduino to understand g-code. When i start g code motors is only moving very little steps. What is recommended voltage for cd drive stepper motors? Can i edit scale from "idle code" or g-code?

What program are you using on the Arduino?

If it is an off-the-shelf program perhaps it has a website to answer your questions.

If it is a program you wrote yourself please post it here, or attach it if it is too long.
