I got some materials around and came with the idea to build a homemade 2D printer a really basic one nothing complicated. I just came to share the idea and ask in between few questions that I'm interested.
So the idea is to build a 2D printer using the following materials:
2x DC motors 1x servo motor 1x 2port DC motors controller Arduino Uno IR Sensors (leds, transmiter/emitter) long screw rod nuts and bolts square platic material plate (I got it our from a 17Inch LCD) power supply cables..etc
So the main frame is to connect the 1x dc motor with a screw rod bellow the plastic plate so the plate will act as Y.axe and above the plate a X.axe crew rod with DC motor and in the middle of the rod a Servo motor to touch down and get up the pen/marker. So as we know the DC motors can't be controlled as step motors and for what we need a long paper with [u]white[/u] and black lines which we gonna determine the actual position of the 0 point axe (of the pen/marker) using the black/white lines and the infra red sensors.
[u]Quick rev. about the IR sensors/ how they work[/u] So we got 2x infra red sensors, one is transmiter which acts as a regular led (you can't see it) and the other one as receiver which get the infra red light and said ("hey i can see the light"). That 2 leds are close to each other but separated in between with something, when the IR led is on the light reflect the "wall/object" and the IR receivers gets the data/light. If the "wall" is white then it reflects the light but if the "wall" is black it does not. So that's how we get the steps with DC motors. We put one of those for each axe.
So my question now is: ../I got an idea how to insert few characters to print them out as axe coordonates but i need to write them manually, is there a software which can make the characters in cords?
That will not work but looks like I'll need to create a software based on my step/cords which I'm gonna write text and send the cords to arduino.
Another question is: Should I better use 2x servos to white the letter of keep it as it is?
