Thermoplastics in 3D printing

Today I find some useful info about...

 Generic Families of Plastic 

Typical Characteristics of Some Important Plastics

RAMPS GADGETS3D LCD and SHIELD v1.0

I want to have ability to run my ALF3Dpi without PC. That's why I need this thing...

Configurations and info HERE
It consists of two main pieces and wires
1. LCD with SD card connector

 2. Shield for connecting it to Arduini through RAMPS

and as I said there 2 10pin cables with it (there also was SD card with kit)

Now lets attach them togather
First step is assembling shield with RAMPS

Second step is defining correspondings connectors EXP1 and EXP2 on shield and LCD

And the third sted is connecting them to each other

Now can use SD card

Completed and ready to go

PS I found some sticker on LCD  it is Buzzer

And CAD model from GRABCAD
To be continued...

Arduino MEGA 2560 + RAMPS 1.4.... first blood

I tried to attach my Arduino with my RAMPS and what I have seen....(

Soldered pin on RAMPS don't let them come togather(
Need to work with file and remove it gently as I can.

SDRamps for RAMPS 1.3/1.4

In kit that I bought was included this thing

This is the way to connect it to RAMPS

As you can see not all pins on SDRamps are used.

 But because I will use RAMPS GADGETS3D LCD and SHIELD v1.0. I don't need them this time.

Pololu stepper driver board A4988 rev1

Stepper motor dravers, that my Arduini runs trough RAMPS is Pololu A4988 chib based.

I have 5 of them...
Stepper driver board information about my drivers I founr HERE
This is modifications of original board. One of resistors was changed on resistor which I can adjust to change motor current. But in general it's the same.

This is wiring diagram

And jumper settings (jumpers are on RAMPS board).

Want to say that this board must be installed in RAMPS this way

BUT NEVER THIS WAY!!!
