Re: Help me control a stepper motor pleaaase

i just finished making the instructables and it works well. like you said the encoder hasnt got enough steps for my desired control and i now need an encoder that has more like 64 steps. i've been looking and i dont understand a lot of the information that encoder data sheets show. i know that it needs 64 ppr, 2 channels, 90 degrees square wave, but what i dont understand is the contact rating. the one i used is a 10mA 5V DC. would it matter if it is say a 1mA 10v or a 10mA 10v. i say this because i have a few encoders with different ratings they work with my circuit. will it cause damage or poor performance if the rating of the encoder is wrong?

thanks
