E3CNC - CNC dựa trên Ender 3 Pro!

This is an Ender 3 Pro based CNC!

----------------------------------------------------------------------------------------------------------------

• Reusing as much as possible from the Ender 3 PRO down to the screws.

• As of now BOM cost is ~60$ on Aliexpress (without sale/coupons) not counting the Ender 3 PRO or dremel/spindle/router. But chances are you have some of the BOM laying around already.

• GPL-3.0 license!

• Easy to scale up or down to any size if not using Ender 3 Pro frame.

• Easy to fit any small size cheap spindle.

• Can be run on Klipper, only needs slight tweaks to some macros and a few new ones for easy setup! (Already working and will be uploaded to the GitHub page)

Reusing from the Ender 3 Pro:

• Frame

• Steppers

• Wires (need to extend some)

• Leadscrew

• Leadscrew nut

• Coupler

• MCU

• PSU

• Most of the nuts and bolts

• Vslot wheels

• Alu spacers

• Screen if you want

My setup:

Im just running the original MCU with Klipper for the control and Fusion360 for CAM (free version) with a klipperized post processor. So far no real issues. You might want to swap to a board with TMC control (skr pico/micro4) if you really want to push it.  Im using an old laptop with Ubuntu with klipper on as a substitute for a Raspberry pi. 

You can of course go the GRBL route if you want. I just wanted to use Klipper since people coming from 3D printers are somewhat familiar with that.

NOTE!  No design history in Fusion sadly. There are clamps for various Ø52 - Ø65mm routers/spindles. Only 2 dremel-clones have been tested to fit, yours might need tweaks to the dremel clamp system. If you need help please contact me and ill do my best.  

Print settings I used: PLA+, 5 wall, 5 top, 5 bottom, 40% gyroid.

Story: 

I had a wish to learn more CAD and had lots of random parts laying around, tossed them into Fusion and started working on it. 

This lead to the birth of the “old” project Endercnc. Based on only parts i already had laying around, making this a mix of an Ender 3 Pro and the Ender 4. 

After working on it and testing it out it worked way better that i would have expected, but it felt “finished” but not really build-able for others without a bigger BOM cost. 

So, what do a lot of people have sitting around collecting dust? Ender 3 Pro's! So I set out to make a new cheaper and easier to build version that is ONLY based on the Ender 3 Pro, down to the screws! 

Special thanks to Steve for beta testing and ideas. Crys and Neohhhh for valuable input and ideas!
