Hai...i'm freshmen in robotic. Correct me if i'm wrong.
I'm doing XY Plotter.
I already have 2 hybrid stepper motor :
1. Size 17 (6 wires) - RS 440-420
2. Size 23 (8 wires) - RS 191-8384

i already found control board RS440-098 http://malaysia.rs-online.com/web/search/searchBrowseAction.html?method=getProduct&R=0440098but very costly..
Have any idea other than this driver or other way to drive the stepper motor?

You may use Cytron's SD02B stepper driver.

how to connect encoder and 2 stepper motor at the same time?do i need different interface board?

Usually for a stepper system, encoder is not needed as the motor itself is highly accurate in operation. Any reason why u want to connect the encoder? What's it for?

I would like to build a robot which can draw curves with a pen. The size of drawing area would be something like 30 x 40 cm (A3), it would plot just in 2D so X and Y only. And for now, the pen could just either touch the paper or not and is just glued to the arm.

I really would like it to be very precise (so it could draw straight lines or circles). It doesn't have to be very fast and it's ok to have complex software.

My questions are:

I want build "Scara" type robot, like:
http://maschinenringraum.blogspot.com/2009/06/articulated-plotting-robot-for-10.html

-I have 2 stepper motor and 2 encoder (potentiometer:to measure the angle of rotation of the arm). How to develop the board for these hardware using cytron stuffs?

-Is there another way more cheap to build xy plotter scara type? i mean using another motor and also driver

- It is possible to know when a line to draw ends so the robot could gradually slowdown
