CoreXY Ender 3

Description

I love my Ender 3, but it is so 2018... In this build i will try to convert it to a coreXY printer and add Klipper to it. Notes: my Ender 3 was not a "stock Ender" i had done few modifications on it - Dual Z upgrade. - Direct drive extruder - Board remplacement by a SKR 1.3 with TMC driver. However, i think this build can work without that.

Ender_Core_XY_Linearrails_Enclosed_Beta.zip

***BOM to come soon.***This is a beta of the enclosed 2020 chassis conversion. Since it's in beta, it may still have a few quirks. Power supply mounting is still less than ideal. Would recommend replacing the four frame braces on the bottom with an acrylic panel that the PSU could be taped to using 3M VHB.

Marlin-2.1.2_for_Ender_CoreXY.zip

This is Marlin 2.1.2 configured for the Linear Rail Version. It has some quirks and features so I strongly advice reading the Readme and skipping through the Code yourself. Have fun!

Ender_Core_XY_Linearrails.step

Version that uses linear rails for the XY-Gantry. All parts that are modified from the original version are yellow and dark green. You will need 3x 350mm Mgn12h, M3,M4,M5 bolts, 370mm 2020 and 2 Motherboard standoffs that are used to mount the hotend. If you have questions regarding the conversion i.e. the firmware, don't hesitate to ask!

Thanks to @Barzar who did a really great job working on the v0.2 with linear rails !
Got it !

V0.1 release and V0.2
Tanguy • 08/27/2022 at 16:32 • 0 comments

I am gonna release the current version (V0.1) as a single .step file with the full assembly inside.

As you can see in the videos, the V0.1 prints quite well, but it lacks a lot of little things to make it clean (cable management, proper endstop emplacement etc..)

But I am not gonna do that in this version, I want to make it better with linear rail on X/Y, that will be the V0.2
Working on all the little things that need to be done to clean this up

Hello! First of all, I want to say that your project is really interesting! Currently, I'm gathering parts for it and studying the step-file, and I have a question: is there any type of belt tensioner? Or are the belts tensioned only during installation?

Are you sure? yes | no

merhaba, ben türkiye den takip ediyorum sizi ve ne yazık ki yeterli ingilizcem olmadığı için türkçe yazıyorum size. projenizin v slot olan V01 i yapıyorum. orjinal ender3 kartını kullanıyorum (creality 3d v.1.1.4). proje neredeyse tamamlanmak üzere ama marlin firmware derlemesini yapamadığım için sona ulaşamıyorum. config.h dosyasını nasıl düzenleyeceğim hakkında bilgi verebilir misiniz. yardımlarınız için şimdiden teşekkür ederim.

Google translate :)

Hello, I follow you from Turkey and unfortunately I write you in Turkish because I don't have enough English. I'm doing the V01, the V slot of your project. I use the original Ender3 card (Creality 3D v.1.1.4). The project is about to be completed, but I cannot reach the end because I cannot compile Marlin firmware. Can you tell me about how to edit the Config.h file. Thank you in advance for your help.

Are you sure? yes | no

diğer 2 yazıcımda klipper kullanıyorum ve haklısınız, ancak bu cihaz şimdilik elde olmayan sebeplerden dolayı marlin ile çalışmalı. aslında orjinal ender 3 marlin yazılımını sadece corexy seçeneğini değiştirerek derledim ama x ve y eksenlerini home pozisyonuna çağırdığımda hareket etmiyorlar. menüden eksenleri hareket ettirdiğimde x ve y eksenleri ileri doğru hareket etmelerine rağmen, geri hareket ettirmek istediğimde yanıt vermiyor. neyi yanlış yaptığımı da bilmediğim içinmakina aptal bi şekilde kaldı. bu makinayı üniversitede öğrenciler kullansın diye ücretsiz olarak yapıyorum ama başarısız olmak üzereyim.

lineer ray için yayınladığınız marlin dosyasındaki değişkenleri uygulasam olurmu, onu da bilemiyorum.

hello

1st of all thank you for this project

just a question, what infill you used and filament?

i'll use ASA from Azurefilm in the linear rail's option, but i'm still struggling with the amount of infill and type

thank you in advance

cheers

thanks!

i'm printing 50% infill 4 layers bottom/top and walls

this should be in things to share the "mades" :D

really forward to see mine built !!

What happened with this project? Is it doable? Not much information and no answers to the questions asked...

Are you sure? yes | no

Hey!

I'm currently ordering all parts for the conversion, and saw you wrote in the linear rail BOM 350mm rails, but wrote that you ordered 310mm. Which one is it? Asking mainly because I (and probably many others that modded their ender3 with rails) have 310mm rails and it would be a shame to buy another set if it's just a typo.

Are you sure? yes | no

Barzar wrote 11/16/2023 at 09:08

The Conversion does also work with 310mm rails. The y-gantry rails won't be a problem since they go under the rear stepper mounts and the x-gantry rail will work if you mount the rail center and change the x-max in the firmware.

You will still have the full build volume.

Are you sure? yes | no

fedorchenkovasiliy wrote 05/07/2023 at 07:08

Hello! Is there a chance you could download the models for the 3d printed components in the .stl format? I am planning a conversion using roller bearings for XY.

Perhaps, you would be interested to make your project page on the thingiverse so that more people see it.

Thank you!

Are you sure? yes | no

I’ve been working on converting my Ender and I’ve got all the mechanical stuff working but I’m wondering what you did for the firmware. I’ve been able to get one test print off but I’m getting prints at an angle with x and y dimensions that are totally off. If you could give me any information that would be great!

Are you sure? yes | no

Barzar wrote 01/26/2023 at 17:50

Is your printer moving right when you move it manually?
What steps/mm value are you using on your x and y?

Are you sure? yes | no

Barzar wrote 11/23/2022 at 11:45

Awesome project. I just got my ender 3 printing perfectly again but this looks way too cool. Why did you choose too keep the direct drive and print realtively slowly for a corexy? What are you max print speeds on this maschine?

Are you sure? yes | no

schwartz.blake wrote 09/04/2022 at 02:46

Amazing Project! Where are you with print speed?

Are you sure? yes | no

MakerIoT2020 wrote 07/28/2022 at 05:29

This is quite an interesting and involved project. I recently decided to bite the bullet and buy a desktop CNC mill, as I need to cut and shape more than print. 3D printing is however on my list, and this may just give me some ideas on how to improve whatever 3D printer I do eventually get (I Was looking at Ender 3 myself, yes they are old, but so very hackable)...

Good luck with the rest of the project:)

Are you sure? yes | no

Tanguy wrote 07/29/2022 at 09:47

Yes, I think the Ender 3 is still a good first 3D printer, and used ones get really cheap. (I got this one for 100e)

Thanks !
