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:

-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
