Getting into 3d Printing

Good morning mik_wind

First of all, thanks for your response and for your great ideas.

respecting to the reading your post i have to say just a thing, the DELTA printer is so expensive, only looking for all the joints and sliding points, i thought in a printer in where the X and Y axes are separated and only the Z axis is on the printer base, sliding the hot bed forward and backwards, while the Y axis just "pulls" the rails of the X axis using pulleys also using the simplest part of the recycled printer: the printer head's rack and pinion in where a motor is screwed on the base of the printer and on the top only a pulley for pull all the weight of the x axis,

For the X axis i will use the SAME system rack and pinion, or using two motors spinning in the same direction all for reduce the wheight of the extruder.

i have calculated all the costs and i only will have to pay between 25/50€ and that's just counting on the two printers used for pieces and materials.

later i will upload an draw for what i want to do

Hi To Everyone,

Here's an diagram for the design of my 3D printer, in this sketch we can see all the mechanical parts for moving the axes and extruder, like i said the Z- axis is mounted apart from the X and Y axes,

I WILL NOT USE STEPPER MOTOR FOR MOVING THE EXTRUDER, i will use a system called, optoelectronic sensors, this system is formed by: A optoelectronic reader and an encoder strip, when the sensor moves it reads the strip and tells to the arduino and the software where the extruder is located in the axis, and i think using an H-Bridge will be like an stepper motor.

@XarlyCodeX,

Looks like you are making some excellent progress towards your 3D printer. I have seen several attempts to use rotary encoders and DC motors through an H-Bridge instead of steppers. If you can make it work, make sure to share your exploration, as that could be the key to bringing 3D printer costs under $200 USD!

Keep up the great work!

KKHausman,

I have good news,

Searching by Internet, i found that the "real name" of the optoelectronic sensor is Photo Interrupter, also i thought in the conveyor belt used in supermarkets; when a product reach the sensors, it cuts the communication between the emitter and the reciever, the conveyor stops, i think that i could use that idea for knowing HOW this photo interrupter WORKS, and when i get to the information i need, i will can start using the encoder strip for read the pits of it.

Now i feel i'm closer to know the "secrets" of the hardcore electronics

Very good new, Xarly Code X, the captive photo interrupter is a good design and very robust whenever you have a path that allows interruption along the axis of movement you want to test.

The emitter (E) transmits an optical signal to the sensor (S), which is latched as a digital 1 until interrupted, when it falls to a 0 state. We commonly use designs like this for pinewood derby car races and other actions that have an ad-hoc measure threshold within a defined region of completion. More detail is available for using with an Arduino microcontroller at: http://forum.arduino.cc/index.php/topic,20750.0.html

You can also adapt the ATTiny85 microcontroller to run most Arduino code (also Atmel-based) on a much smaller form factor if you need to embed the controller in a space-constrained area.Details on that are here: http://makezine.com/2011/10/10/how-to-shrinkify-your-arduino-projects/

Keep it up!
