UPDATE 5: I've updated the link to the lastest stable version of Marlin. As always do a PID tune and make sure your thermosistors are set accordingly. I also have enabled mesh bed leveling. You can find the option under Prepare > Level Bed. Just follow the onscreen directions.
UPDATE 4: I've updated the link to the firmware I'm running on my Ramps 1.4 to Marlin 1.1.0 RC8 Bugfix. As always do a PID tune and adjust your E-Steps accordingly. I've also enabled mesh bed leveling which works very well.
UPDATE 3: I've uploaded my endstop mount for my particular endstop (not stock) and one for the stock di3 endstop which I pulled from my previous bowden setup I was running which is my friends upload where you can find it here.
UPDATE 2: I've installed the new carriage and it works perfectly. Check out the pics for the new setup.
UPDATE: I've uploaded a version of the X-carriage with the double holes like the cable-chain uses. I'm also going to see if I can edit it where I have my end stop at and make it so it is adjustable. I'm going to print the modified carriage today and install it tomorrow hopefully if everything goes how I want.
On my search to get better prints out of my MakerSelect, I upgraded my printer a few months after having it and converted to a Bowden style E3D v6 hot-end. Used it for quite a few months and was happy with print quality. But there was one thing I wasn't happy with. Not being able to print flexible materials. So I searched for some extruder designs here on thingiverse and wasn't satisfied with any of them until I came across one for another i3 style printer. Then I did a little research on the MK2. The Prusa MK2 is one of the best printers on the market in its price range. So I decided why not use that setup.
There is no modifications you need to do to the printer itself besides needing to tidy up your wiring. The X-Carriage is a direct fit for the X-Axis rails. Only things you need is the hardware to put the extruder body together, a 50mm radial fan, 30mm fan and a E3D v6 hotend (a clone will work just fine as that is what I'm using).
All the files (besides the modified x-carriage) I'm posting can be found on the Prusa website free to download but, I decided to post them here for ease of download.
I've modified the X-Carriage to allow you to use your drag chain so it not drooping down. On the original Prusa MK2 to compensate for this they use a 3mm nylon filament piece that is about 50cm in length that runs along the wire all the way to the control box. I attempted this with our 1.75 filament but, it did not work so well.
