Custom CoreXY Ender 3 Pro Prototype

Подписаться 20

50% 1

This is my custom CoreXY-converted Ender 3 Pro, loosely based on the design from Tanguy on Hackaday.
This project is still in very early stages. I have since redesigned the motion system and motor mounting/belt tensioning, and am planning on adding a third Z-axis motor for automatic Z leveling.
Settings in above video:
150mm/s speed
11000mm/s² acceleration
.2mm layer height
.4mm nozzle
Motion system has tested as high as 400mm/s, 17000mm/s² but my hotend can't keep up.
Please let me know any questions you've got about the printer in the comments, I'd be glad to answer them. Once I've got a tried and true design, I'll add the STEP file and BOM to the Hackaday project below.

This is cool. I have been looking at a way to reuse the parts on my ender3.You should start a new Project as this looks quite different from the tanguy project.

I have thinking about moving it to a new project. I think I will once I finish the mounting solution for the electronics.

Really cool! I'm currently looking into options for making a linear rail corexy from a gutted Ender and stuff I have lying, and this seems like a really nice design. Gotta dig through these original designs. Looking forward to updates :)

Thank you! I'll be posting an update soon. I've begun shifting the Z axis to a three motor design. I was running into problems with the bed throwing itself far enough out of level that a probe couldn't fix it whenever I lifted the print sheet off, so I am working on implementing a 3-point mount.

I made something very similar with my ender 3. But I'm going to change it since mine is hard to enclose because of the ender 3 extrusions and my bed isn't rigid.

@AaronDeister99 18 дней назад

That was the challenge I ran into when using the original Ender 3 extrusions as well. I wanted this to double as an ABS workhorse and enclosure just isn't really doable with the original extrusions, so I ended up buying 10x 1000mm 2020 extrusions to build a frame.

Nice, how’s the hgx extruder? Got one on the way rn

@AaronDeister99 19 дней назад

HGX has been great. While it's definitely not as light as some other large gear extruders, it still gets the job done at a fraction of the price and is an absolute tank.

what is the full link to the project, it is cut off in the description.

hackaday.io/project/186229-corexy-ender-3 Sorry about that - I had uploaded this over mobile which messed up the link. I'll fix the link in the description.

Is this an ender 3 at this point?

@silencedfrost901 Месяц назад

I came to ask the same

@AaronDeister99 Месяц назад

Honestly, not much, no. But it is still capable of reusing the bed, motors, and a few other components. I'd also like to publish a version that still uses V-rollers to keep it a bit more affordable.

That's cool and all but nothing about that is Ender 3.

@AaronDeister99 19 дней назад

See my reply to FlapD's comment - there are actually still a few parts from the E3 that can still be kept, and I'm working to introduce a bit more compatibility for the original parts for those who want to keep it on a budget. The next two things I'd like to do is allow for compatibility with the E3's extruder/motor and add compatibility with the original hotend. Currently this is compatible with the original bed, motors, and power supply. While the frame is different, that was a choice I made because the original frame really doesn't allow for an enclosed CoreXY design.
