Post your problems and question here on the forum, there is a lot off people out here who want to help you.

go to bq site (spain)
search for prusa i3
get all the instruction manuals, they are devided by steps and in english and very explicit.
you got there everything to construct your prusa i3
for the heat bed you will have in this forum all the help you need. i'm in portugal so i can't help you in person. i would if i could and for free.

Hello I am also new to 3d printers but I have some experience in electronics, and I started to build a printer after prusa i3 build manual. I have the first biggest issue: I want to wire the end-stops for Prusa I3 rework and I don't know the schematic for that I just sow that 3 wires are connected => important to connect in right order. the switch has one pin common one normally closed and one normally opened. I don't know the order.
And another question I want to use stepper motors from old saved from old printers and the wiring of the motors with 6 pin stepers (unipolar steppers) but if I use them like: coil-end coil-end it is an bipolar stepper, it is OK?
Thank You!

Hi, are these the endstops you have?
If so, you can leave one GND wire disconnected. Vcc goes to "+" on the board, GND to "-" and S to "s"

Hi, these is my endstop (microswitch) please tell me witch pin goes from the microsw to the ramps board . which number for color?
Thanks!

1 & 2 connect to the "-" and "S" pins

Here is the full answer! Thank A LOT!

can you please show a picture of it once you have it wired? I have a faulty end stop that I am replacing and want to do the same thing as you

I am new to this forum and the printing world. I just bought a pursa i3 kit and have it all assembled and all my axis home and work except for my extruder. I know my stepper motor works because I have unplugged my x axis control and used it on extruder and it worked just fine. I have heated the hot end and bed to temperature and still no luck. I have also gone in and switched around the pins in the software with no avail.

I have a mega r3 2560 with ramps 1.4 using Marlin software and pronterface for my control.

Can anyone help me?

Try swapping the motor drivers to see if the driver is broken.

I want to make that schematic for Debouncing the microswitch , i will post it once is ready, now i am planing ho to place the PCB board. if you simple want to wire the microswitch just wire it like (color matching the ramps pic if it doesent written on your ramp PC

Can anyone tell me after I upload the Marlin firmweare on to the arduino i Can acces it from Pronterface or I need to something else. thanks!

I think on Windows you need USB drivers
[arduino.cc]

Linux should work directly, make sure you set the baudrate the same as in the firmware

The power source for the ramps connetcor is both with 12V ?

I don't own an RAMPS. Perhaps google the schematics ;-)

Yes, both are 12V - the removable green plugs.
