First of all, thank you very much Misan. Yes, you're right, I don't have jumpers and that's way I divide the values by 16, I'm waiting my jumpers by post because the shop forgot to provide them when I bought the RAMPs, and belive me that's a really noisy machine! :O
On picture is shown how I connected the Z motors, do you think I'll get the controll of the Z motors with the jumpers?? They are ri

As a summarize and after 3 days just trying trying and trying, 3 of my 4 pololu are gonne compleatly. After change them by new ones, problem didn't finish and still motors didn't move. To get them moving, I just had to divide by 16 the step_per_unit value and after that, just try it and calculate the correct value with the Josef online calculator. For now just a problem, X,Y and extruder motor ar

Well, I still can't move my motors. Just vibrating. I have tried all what I could think it could be wrong. Motors wiring, firmware (I tried some differents with same issue), change stepsticks for new ones, tested with Martinj testcode and nothing new.
Lost in this case, if someone could help it will be very wellcome. Thank you to everyone.

Sorry for this long post but I would like to attach all the "important" starting configuration and see if someone see why my motors make the noise like they are moving but they don't move:
// BASIC SETTINGS: select your board type, thermistor type, axis scaling, and endstop configuration
//// The following define selects which electronics board you have. Please choose the one that matches your

I gave a little more current from pololu pot and it turn a little but it turns untill a limited angle. This happens with all the motors. I don't know what it can be.. Could I try to disconnect from RAMPs the three endstop and it could work? or it won't work any motor without endstop plugged on RAMP? Just for testing..

Hello everyone,
Thousand of thanks for your help, I found and solved the problem, it was a electrical problem with power supply.
Well, now I got the motors connected and with Pronterface I send the order to move i.e. Z motors +10 or -10, the motors make the noise like they are moving but they don't. I thought it could be a low power was comming in to them and I turned right a little more t

Hello,
I bought a RAMPs 1.4 and now I started to build my Prusa. Well, I wanted to try the NEMA 17 motors and I connected them to the RAMPs in this order
2A = red
2B = blue
1B = green
1A = black
They don't move. I changed the option (board selection) on Sprinter firmware and I choose 33 to chose the RAMPs 1.3 (1.4 is not availabe for selection). I also tried disconnecting my endstop from boar

Aquí un enlace a Slic3r, si que trabaja con windows.
Por cierto, tiene muy buena pinta, y las imagenes de algun que otro blog son increibles de la resolucion de la impresión 0.08/0.09 mm por capa y una velocidad de procesamiento en los calculos muy superiores a Skeinforge.. a ver que tal nos va a nosotros.
Saludos

I would like to use that silicone instead of aluminium foil to fit the heat resistor to the heater block but I'm not sure if it will transmit all the heating energy to the block or it'll decrease this temperature transmit. Thanks

Hola, como comenté anteriormente, estoy montando mi Prusa. Todavia no dispongo de los motores pero si que tengo toda la electrónica lista. Una pregunta, ¿existe alguna forma de testear esta electrónica y comprobar su estado (RAMPs 1.4 , Polulu A4983, Arduino MEGA 2560? Lo comento porque parte de la electrónica la he recibido en no las mejores condiciones posibles a mi entender y necesito saber si

Yo tengo Arduino 2560, RAMPs v1.4, polulu A4983.. y no tengo mucha idea de qué cableado poner. He visto este tipo de cables, y en principio salvo para placa calefatora y extrusor (en los que usaré este cable probablemente: https://shop.grrf.de/nichrome-heated-filament-1m-p-247.html ) usaré este tipo de cableado ( https://shop.grrf.de/cable-control-wire-black-1m-p-236.html ), si alguien no dice l
