    Now that i think about it Great Idea! because i'm using meccano i can easily gear the motors! The only problem with that is that it will make it noisier :( How long does it take to draw an image? (Obviously it depends) On average for a "normal" piece of paper

    When i say "accurate enough" with a 0.5 mm pen, I mean that if i divided the drawing surface into 0.5mm spaces. Would the motors be able to move the pen to each 0.5mm space? Yes, my motors are 48 steps per revolution (360 / 7.5) and if you turn the motor by hand i count only 13 steps per revolution. I'm 100% sure my motors are not geared.

    Your stepper motors are 400 steps per revolution (0.9 degree per step). My stepper motors are 48 steps per revolution (7.5 degree per step). I will probably use about a 1 inch diameter pulley. Do you think it will be accurate enough to be able to draw details with a 0.5 mm pen?

    Compiling from the source files worked :)

    Hi, I noticed that you used four wire stepper motors.Would it work if i used 5 wire stepper motors? Is there somewhere to set that in the software? (I would be using my own chip to control the stepper motors instead of the motor driver boards)

    Great!Also, when I try to run the controller software on my 64 bit machine running windows 10 the default.properties file is created but nothing is displayed. I've played with the compatibility settings, but still nothing :(What OS do you run it on?Could I run the Linux version on a raspberry pi?
