Hi! Thank you for you instructables. I'm trying to build one. I've a power problem: if i try the laser without the npn transistor and the connection to Arduino I get 160mA on the laser (tested with the laser test circuit). If I connect the NPN and the arduino I get insufficient amperes to make the laser burn something. I'm using 10V as source for LM317 and Laser (mine is a 5V 200mA) and if I connect that ground to the transistor emitter the laser isn't turned on/off by M5 command, the same if I use arduino ground. To make the switch work I'm using the ground from the +5V source I use for stepper motors. Do I have to recalculate the resistors or I'm doing something wrong?Thanks in advance!
Ok, I was doing something wrong! Ground must be the same!! So I connected to 12V instead of 10V and everithing turned ok! 12V and 5V share the ground on ATX power supply while 10V doesn't Thanks again!

Hi!I made this but i can't see any change in the Arduino pin 12 with commands M3 or M5: i attached a tester and it reads always 5V. Can you help me?Thank you!

Hi, could you please explain what you did with the Attiny85 and the servo?
Thank you!Sorry i'm a newby... the Z Pin is the #4 labelled 'Step pulse Z axis'?Is there other circuitry between the attiny85 and the servo?

Yes, that's a DC motor. Sorry i didn't see the two wires.Here it is: http://i.ebayimg.com/00/s/NzI3WDEwMDA=/z/3acAAOSwM...
Look at this video and remember that the easydriver used in this project is a bipolar driverhttps://www.youtube.com/watch?v=lduqo4fmXYo
Can't tell from your photo... you should look to the motor, not the circuit attached to it. If the motor has only 2 wires, it's a DC motor.
