Summary

Important notice: The Projects has moved to https://www.blvprojects.com
due to the last unsuccessful Thingiverese update, all the text and instruction became a complete mess. Therefore I decided to build a new website for the projects: https://www.blvprojects.com You are more than welcome to visit and build your own BLV printer.
Thank you :)

BLV mgn12 mod for Anet A8 / AM8

The main purpose of this project is: converting your Anet A8 into an incredible 3d printer, using MGN12 rails fixed on an aluminium extrusion frame.
This upgrade compatible with pheneeny's AM8 mod with small changes. (Huge credit!)
Why mgn?
The linear bearing and Delrin Wheel Gantry commonly used at most of low-mid 3d printers as a cheaper solution for linear motion. Its cheaper replacement for the expensive mgn rails BUT price is at the expense of accuracy and reliability. Well, linear guided rails (mgn rails) are much more rigid, extreme precise and smooth then linear bearing or Delrin. The linear rails lets you print with higher speed - shorting print time without compromising print quality. The fact rails are fixed to frame prevents unwanted motion related to bent threaded rods or other axis's motion. There seems to be a good reason why they are mostly used with high end 3d printers..
So, i found cheap chinese mgn rails at Aliexpress and thought to myself why not?

IMPORTANT

fixing the mgn rails can be very frustrating. it need to be perfectly aligned and straight.
else, it will give you a headache, so don't start this project without tons of patience.

design flexibility and Source file
I'm sharing with you the source file of this project in order to improve the design and make it even more better. you will find the STEP file inside the project zip.
Please follow the item license (under the Creative Commons - Attribution - Non-Commercial - Share Alike.).
If you are using the STEP file, please don't forget to mark it as a Remix :)
Also made for this project a Build plate for simplify3d

Please notice you may need to re-center bed coordinates via marlin configuration
or change Z extrusion position to center the hotbed

Build it at your own risk.

Latest video update
A quick peek at my project building progress.
sorry for all the exposed wires - i had to test it. first video after all axis's electronics had been connected. Next week i'll get the 400mm threaded rods and install the rest.
I had to reverse x-motor connector in this video beacuse mistakly i fixed the carriage screw on the back instead on the front (i fixed and uploaded the fixed x carriage).

Seeing all of this great community members uploading photos and remixes worth all of the long hours that i have put into this project :)
I will appreciate if you could please upload an "I made one" photos :)
Thank you guys !!!
