Are the encoder pulses to the parallel port supposed to be 12v?
Most I have seen suggested were 5v.

Hi
I connected an encoder to lpt1 and I assigned the correct pin in mpg view. Now when I rotate the encoder the axes doesn't respect the movmet if I turn the encoder in clocwise the axis (x) goes in positive way but during the turn it goes in negative way then in positive way, I don't know which encoder I have, I have only the square wave from my oscilloscope. The encoder has 4 wire positive negative A and B
I hope to be clear
Again I'm sorry for my english

Learn cause and effect through experience. Mastering those relationships is the "Common Sense" ability within the art of any trade.
In the picture you can see 12 volt but i tried theencoder with 5 volt

Could be stray noise in the signal between the encoder and Parallel port or betweeen the port and the stepper driver, or a dirty encoder wheel? Since you have a scope, you should be able to detect that.

I will try
