TNS's E3D V6 Carriage - Adjustable Edition by GrkMangas

Last crawled date: 3 years, 1 month ago

Introduction
The purpose of this remix is to increase the smoothness of the X axis movements for TNS's E3D v6 Carriage. The parts where created to allow X axis parts with a variety of X rod distance to be used and still allow smooth movements. This project first started when I noticed that after installation of my new igus bearing holders (the purpose was to eliminate the heavy play caused by putting Igus bearings in the aluminum blocks. They are not a tight fit at all and cause small defects to appear) it required a lot more force to move. Looking into this more I noticed that my X rod distance where measured 45.75mm while the carriage was designed for rod spacings of 45.95mm. This small difference caused a lot of force required to move it.
My aim was to design the carriage in such a way to allow different rod spacing to be used. An example is that Leo_N's X axis parts (https://www.thingiverse.com/thing:1919544) will have issues as the center rod to rod distance is only 45mm instead of 45.95mm. This remix solves that. Let's say that you aren't using an Anet and you are using a Prusa i3 clone. This should work with that as well as long as the center rod to rod distance is between 44mm to 47mm.
These parts where all created ground up in Fusion 360. I don't have OpenScad so I had to use the original stl's for dimensional references.

Features added
-Allows for center rod to rod spacings of 44-47mm to be used.
-Different version for 4 bearing printers
-Adjustable fan height feature to allow for more fans to be used or to allow user to adjust fan to the perfect height.
-Fixes some of the dimensions on the original model.
-Not printer specific, can be used on other printer models
-Interchangeable with the Caps for TNS's parts.
-Fusion 360 files provided. Go nuts and remix this.
Changes
4/24/2018 - 4 Bearing .STL version taken down for now. I need to design a belt holder for this version. Once I create or find a solution, I will be posting it up. I am leaving the Fusion 360 files up if anyone still wants to play with it.
5/2/18 - Added the 4 Bearing Holder with it's Belt holder bearing block. I integrated both components together in other to solve the issue. I also updated the .stl and removed the old belt holder holes. They are no longer needed for this set up. This update only effects the 4 bearing version.
9/9/2018 - Updated the holder. Decreased the size of the holder so that it sort of clamps onto the E3D. Originally it was designed to specs of the E3D but I noticed that it started to wiggle in the mount. Made it a tad bit smaller so that it just clamps onto it stronger.
9/19/2018 - Updated the fan holder. Creating a new blower has caused me to notice a few issues with the old placement of the holes which creates the fan to be lob sided.
12/20/2018 - Clipped the corners of the 3 bearing holder. This is to make room for the fan.
Special Assembly Instructions
Most of the assembly instructions can be found here. https://www.thingiverse.com/thing:2099577.
One of the special instructions tho is when attaching your bearing blocks to the carriage, you want the screws on the bottom bearings to be loose until you are ready to add the electronics. That means you will tighten the top bearing screws first and then slowly start screwing in the bottom bearing screws. You want to screw each corner of the bottom screws in a bit and then switch to another one and keep doing that until it is all tight. Move the x axis left and right and make sure it doesn't have too much friction when moving. If you are using Igus bearings with bearing holders like mine, you will feel some resistance as there is no play in them at all. If you are using bearing blocks, they will move very smoothly.
Parts I Used
I am currently using this belt holder by Simhopp. It works great if you are using 16T pulleys on your printer. If you want to use this carriage with 20T pulleys, let me know and I can create something for you.https://www.thingiverse.com/thing:1433295
I am using Leo's Mistral Fan Duct. I like it but now that the height is adjustable, I may try out different fan ducts... I say may because this fan duct kicks butt and I may not want to try other ones :Phttps://www.thingiverse.com/thing:2121279
I'm using these bearing holders. They fit perfectly and are easy to install.https://www.thingiverse.com/thing:2892732
