Geeetech I3 A Pro: E3D V6 + Titan + Cooling

**UPDATE 05.2020** Uploaded a 20-tooth deflection pulley to replace the old ones and reduce ghosting. You will need 4 x "MR93 W2.5" bearings. **UPDATE 02.2020** Did a complete overhaul to my previous version. I decided to use the original mounting plate to install the X-carriage. No more disassembling the entire X-axis or using the original belt holder is necessary. Also, adopted the "Prusa Bear Cooling Fan" to my version. ASSEMBLING COMING SOON! As you can see on the picture, I installed "MaazaFin's Smooth X-Axis". It is not required when using my extruder mount but I highly recommend it. The original X-axis causes the Z-rods to bend when tensioning your extruder belt. You can find it here: https://www.thingiverse.com/thing:1103976 Please do not use flexible couplers for your z-axis like this: They behave like a spring when your steppermotors are moving your x-axis up, especially if you cannot ensure that your x-axis is absolutely horizontal. Therefore, your couplers will absorb torque from your steppermotors and can cause tilting in your x-axis. **UPDATE 07.2019** I was not happy with the mount for the 3D-Touch. The space between nema-motor and 3D-Touch was too small. Very flat screws were needed to install the sensor. With the new version, you can use normal M3 screws. **UPDATE 06.2019** I created a new fan made of four parts instead of one. Here's why: - Printing the fan (in one piece) with materials that have less good bridging behavior like PETG is quite hard. I wanted to reduce the influence of a rough surface on the airflow. - Decided to adopt the "Prusa Bear Fan Bracket". With this, printing the entire cooling fan in one piece is not really practical.  - By dividing it into four parts, it's much easier to print due to lesser printheight and new alignment. - I also made all parts a bit thicker so the fan isn't that fragile as before and the parts are easier to glue. **Credits:** First of all, I have to say thanks to "bliatun" for his great design and sharing his idea. His extruder mount is compact and easy to assemble. So I decided to adjust it to my "Geeetech I3 A Pro". **Goals to achieve:** - Get rid of that heavy MK8 extruder + stepper motor and save weight - Gain more print quality by installing a E3D-V6 and have the possibility to cool filament - Use a probe (BL-Touch) without printing an extra mount **Notes:** - Please check alignment of the printed parts in your slicer software. - If possible, print "Part 4" (nozzle cooling) in ABS - it's close to the heater block. - If you are using the "17HS10-0704S" stepper motor, you have to switch the Connection wires (red + green) as shown in the picture! - Also lower your voltage at your stepper driver to 0.5 volts. That's enough for the pancake motor. - If possible use Loctite Super Glue 3, perfect for gluing PLA or PETG - Don't forget to recalibrate your esteps for your new extruder and check if you have enough tension between filament and the extruder gear.
