Ender 3 dual Z axis with optional frame braces
Description
IMPORTANT NOTICE: Since Thingiverse was having performance issues and people are reporting getting 404 errors, I decided to place all my designs on my own website https://properprinting.pro/product-category/3d-print-files/ All files can be downloaded from there for free and all updates and new designs are placed on there too. A dual Z axis upgrade with a single stepper is in my opinion a must have for the Ender 3 because this increases the accuracy and reliability of the machine. I have designed one which uses standard parts which don't need to be modified and it is combined with the frame braces I have designed earlier https://www.thingiverse.com/thing:3719799 I have added corner pieces without the frame braces if you are just interested in the dual Z axis. I have designed the bracket to be as stiff as possible and therefore it has this odd shape which I am quite happy with. I have made a video about this upgrade in which I show the process https://youtu.be/nBVrcIZ095Y I have bought all parts from RepRapWorld and it happens to be that the 696 mm closed loop timing belt together with the two 60 teeth pulleys have a center distance similar to the two vertical beams. All holes are slotted so it can be adjusted a bit. The power supply must be placed somewhere else and I have seen that there are some mods which enable you to do this. I will make an enclosure soon and this will have impact on the power supply placement so I have not created a solution for this. EDIT: I have created a solution for this: https://www.thingiverse.com/thing:3773553 Please consider buying me a coffee if you liked it or helped you :) http://ko-fi.com/properprinting/
