RAMPS Pre-Assembled Kit Complete

in 3D Printer Controller Kits, RAMPS
We can put 2 motor connectors on the Z driver. For Prusa Mendel the 2 Z motors are driven in parallel.

This is RAMPS 1.4 completely pre-assembled where you will receive all electronic components securely soldered to the PCB, tested & ready for use, one (x1) Arduino Mega 2560 connected to RAMPS, four (x4) Pololu Stepper Drivers w/ heatsinks connected to RAMPS, your choice of mechanical or optical endstop switches & wires, one (x1) USB cable.  We also include loose a 4-pin pluggable terminal block, a 24 pin header & a loose 2nd Diode.  We do not solder this diode in case you use a power supply larger than 12V.

RAMPS - RepRap Arduino Mega Pololu Shield board. This is version 1.4 of our shield, designed to drive a RepRap from an Arduino Mega.  It uses Pololu Stepper Drivers delivering up to 1/16 microstepping.  Four drivers are needed to move most 3D printers, with 3 going to the axis & one driving the extruder.  An optional fifth stepper driver socket has been provided for additional applications.
