Also if now GEEETech proposes the Acrylic Prusa I3 pro series, B for single extruder and C for dual extruder, with metallic idler, I’ve see lot of people that still download my old customization for Printed idler, so I’ve think good to “port” the new version of my customization also on old, printed idler!
Here the Extruder End component of my new customization, you can see from attached picture the all electric contacts are now decoupled on top of this component, so you can easy install it and after install extruder!
The decoupler is designed to support:
2 Complete Extruder, with for each power for Hot End, Cable for Motor and Thermocople
3 Fan, one “always on” and two that connected to the two PWM fans if your board have it, or if you have also the Reprap Ramps1.4 RRD Fan Extender on top of classic RAMPS 1.4
1 three wire AutoBed sensor.
You can see in Schema all component you need, and all the cables are 160cm length to avoid any complexity during installation
In the schema images you can see how all this cables are connected.
PS: I’ve also add the STL for carriage with some small enhancement compared to original GEEETech ones, for example the x belt fixing method copied from the metal carriage, really more easy to put in place, and the holes to enable the unmounts of “just motor” of dual MK8 with black feeder, un mounting just the motor enable to keep Hot end alignment in case of maintenance!
As usual in all my design I’ve splitted all in order to have an easy print of each part, and also an easy mounting after print!
PLEASE PAY ATTENTION: the decouple is NOT SO EASY to create!
You must be good with a soldering iron!!!
IF YOU “FALL IN LOVE” OF THIS DESIGN, PLEASE, REMEMBER THAT IT TAKE TIME TO BE CREATED, DESIGNED AND SHARED… SO “MAYBE” YOU CAN USE THE “TIP DESIGNED” BUTTON ON MY PROFILE!
