Hello I am selling my REPRAP, I bought it for my graduate thesis in Architecture. I was hoping to use it BUT, with new technology I was unable to fix any issues. It stopped printing on day. It was not reading the extruder, it was reading a temp of ZERO. I was trying to find someone to fix it but it’s a very special select field.
The 3D printer was built bye someone who knows how the 3D printer works but they are out of town and I can not find someone to fix it in El Paso, Texas.
All the parts are quality parts, So you can buy it and see if you can make it work. It was working fine and I am certain if you know REPRAP you can make it work for a great price.
It would be a great buy at 800.00
It would take 200.00 To get it printing again
It is securely packed away and ready for shipment. It is a :
Reprap in black ABS, with heated bed, gen4 electronics and Mk6+ extruder.
This gives you a 210 x 210 x 120 mm build area, LCD control panel.
1/16th step drivers which make is nearly silent (I mean that, it's like an inkjet printer),
full gen4 MBI electronics, the Full MK6+ heater and extruder, and the heated build platform.

I've heard really good things about the printrbot's electronics on the
Reprap IRC lately: [
printrbot.com]
I hear it's 99% compatible with the Marlin firmware, and there's a
link to a page on how to make it work. That should change to 100% soon
though. It's also supposed to perform a lot better than current reprap
electronics heat-wise.
If we need to swap the thermocouples, I have 2 thermistors you can have.

HARDWARE
-------------------
Re: Electronics
We (John and I) are using the RAMPS1.4 board and Pololu stepper
drivers which we purchased from UltiMachine.com. The fully assembled
kit including 4 Pololu Stepper Drivers comes to $200.
[ultimachine.com]
We chose Mechanical endstops (which come with the complete kit), and
the Double Connector Z motor connection (PrintrBots, like RepRaps, use
2 Z steppers).
With that and some configuration of the Arduino Firmware to match your
stepper belts/pulleys you could again be printing.
Doing it Cheaper
-------------------------
They offer several levels of pre-assembly: if you are handy with a
soldering iron (and like that sort of thing) you can by a
lesser-assembled kit and trade some of your assembly time for a
somewhat cheaper price.
[ultimachine.com]
Note that if you buy one of the lesser-assembled kits, the Pololus may
not be included. You will need 4: (X,Y,Z and Extruder). The Pololus
can handle 2 steppers on the Z with a single Pololu without issue.
Also note that the Arduino Mega 2560 is not included. Keep this in
mind when comparing cost savings.
Cheapest from UltiMachine would be:
---------------------------------------------------------
RAMPS DIY Kit - $50 (or $65, see below)
4X Pololu Stepper Driver Kits 4 X $14 = $56
Arduino Mega 2560 $65
Assuming you need to buy an Arduino Mega, the parts price comes out to
$171 to $186, so you're paying them about $30 to do all the soldering
and have tested parts out of the box.
If you're sure you want to do more of the work yourself, you still
might consider buying a board with the SMT parts pre-installed unless
you have a VERY steady hand or a solder reflow oven. $65 vs $50
sounds like money well spent.
Re: Thermistor
The 100K thermister we use came from Hotends.com, along with the JHEAD
(beta value of 4066). The Arduino code we are using supports many
"beta" profiles as well as the ability to code up the thermister
response profile in the code, assuming such a table is available for
your machine. The Makerbot Wiki says the "default large thermister"
also has a beta value of 4066, so perhaps this is not a big risk, but
there is some risk here in customizing things.
Re: Heated Beds
The RAMPS 1.4 supports headed beds as well as a 2nd extruder.
SOFTWARE
-------------------
The software we have been using would be different that the code
you're currently used to. We use the following:
Firmware Customization/installation
----------------------------------------------------
Arduino 1.0 (only needed to flash the EEPROM on the Arduino Mega 2560
that is a part of the RAMPS (the "AM" part specifically). You may end
up doing that several times as you tweak performance, however).
Object Design/Creation
----------------------------------
Google Sketchup Pro or Sketchup with the FREE STL exporter plugin
(http://www.guitar-list.com/download-software/convert-sketchup-skp-files-dxf-or-stl)
Open SCAD
Download things from Thingiverse
(other free and commercial solutions are possible)
STL--> GCODE translation
-----------------------------------------
Slic3r
GCode Control
--------------------------
Pronterface - Python-based. You'll need a Python interpreter as well.
We are running on Windows laptops, but all these tools are supported
on Linux as well. I know Peter is using a Linux box to drive things,
but I am not sure what Software Combo he is using.
You've likely been using Skeinforge and ReplicatorG for the latter two
parts. I think those will also work with the RAMPS. The nice thing
about standards is that there are so many to choose from.
