3D Printed 500x400mm Router CNC
Introduction: 3D Printed 500x400mm Router CNC
First of all, I really doesn't like fuss and feathers. Because of that I put the useful area size in the Instructable’s title. The real machine size is around 740x740mm. So, be conscious that you will need some space to place this machine.
In the 2018 I has wandering on the internet when I saw the Router CNC from the Brazilian YouTuber <PERSON>. His project is called "Revolution 2". I fell in love right away! Unfortunately, in those days I wasn't able to make the polymer parts, but those days are gone: I have a DIY 3d Printer!!! Now I'm the king of the hill!!! And more than this, I have a GREAT trainee, a real DIY guy: <PERSON>. Making this real is all his credit.
The main goal of this Instructable is to describe the assembly of the machine, since all parts are available in the Conrado’s web site "Atividade Maker" (sorry, it's in Portuguese). BTW, we redesign ALL the polymer parts in Autodesk Fusion 360 to make the assembly guide, so, you can ask me and I can send you the whole thing!
You may be asking yourself: "Does a 3D Printed 740x74mm sized Router CNC works properly???". Come with me to discover it!!! (in the time this introduction was written the CNC have milling not yet.)
I hope you enjoy this Instructables as much as I did!!!
Supplies
Tips:
* Most of the parts was printed in PETg. 116
I strongly recommend it because of the mechanical stress.
* Use as much as possible lock nuts. The router machine use to shake so much and standard nuts just run away.
* Since in this project all the plates are 3D printed in PETg, we decide to use standard washers, but you should use lock washers if your plates are made from some harder material.
* For this project we've just saved the Conrado's SketchUp files into STL format, sliced in Ultimalker Cura and printed. All the animations are made from the real assembly sequence. Our Fusion 360 files have been redesigned to allocate the lock nuts, simplifying the assembly for future makers. Oh, yeah!
Step 1: Step 1: Z Axis Assembly
As you will see during this Instructables, <PERSON> did an excellent job in the assembly animations, so, there is no much to say buy the parts needed in this step:
Assembly order:
1. Brass nut in the brass nut support; (first animation)
+ Main parts: Brass nut support (3D printed), brass nut.
+ Small parts: 4x M3x25 screws, 4x M3 washers and 4x M3 lock nuts.
2. Brass nut support in the Z baseplate; (second animation)
+ Main parts: Z axis baseplate, brass nut support assembled.
+ Small parts: 2x M5x25 screw, 4x M5 washers, 2x M5 lock nuts.
3. Pillow blocks in the Z baseplate; (third animation)
+ Main parts: Z axis baseplate, 4x pillow blocks.
+ Small parts: 16x M5x25 screws, 16x M5 washers
4. Router supports in the Z baseplate; (forth animation)
+ Main parts: Z axis baseplate, 2x router supports.
+ Small parts: 4x M5x35 screws, 4x M5 washers, 4x M5 lock nuts.
Resume parts:
Main parts:
* 1x Z axis baseplate (3D printed part)
* 1x Brass nut support (3D printed part)
* 2x Router support (3D printed part)
* 4x Pillows blocks 16 mm SC16UU
* 1x Brass nut (T8, Pitch 2 mm, Lead 2 mm)
Screws:
* 4x M3X25 mm
* 18x M5x25 mm
* 4x M5x35 mm
Washers:
* 4x M3
* 24x M5
Nuts:
* 4x M3 lock nuts
* 6x M5 lock nuts
Step 2: Step 2: X Axis Assembly
Assembly order:
Part 1:
1. Pillow blocks in the X baseplate; (first animation)
+ Main parts: X axis baseplate (3D printed part), 4x pillow blocks.
+ Small parts: 16x M5x25 screws, 16x M5 washers
