KAY3D CoreXY Conversion Kit Mk2 Based on Ender 3

(Manufacturing lead times remain at 7-8 weeks from order date until Pandemic Covid-19 situation improves)

Have you ever wanted to do more with your Ender 3/ Ender 3 Pro? Or perhaps, your 2020 new year's resolution is to print faster and better like other high-end machines such as the ultimaker and railcore .. ? 

After much research and development, we're happy to announce that we're finally releasing our CoreXY kit to the market. 

Now the kit is not just any kit. It's a kit only for Ender 3/ Ender 3-Pro users who want to do more with their machines. You want to 3D print faster and better.

It's a kit for the adventurous, but not the faint-hearted. Accompanied with the kit is also handy manual over 250 pages long that has logged down every single detail, picture and instruction to help you build possibly the best CoreXY 3D Printer you can while re-using your Ender 3 Parts

Comes with the kit are CNC precision-machined parts and laser cut plates to ensure that you get the best 3D printing experience possible. No more breaking of acrylic parts or bending of thin aluminium sheets!

The KAY3D CoreXY Conversion Kit comes with:

Non-Cantilevered Design

KAY3D's CoreXY conversion kit also comes with a non-cantilevered design as well. All core components that have idlers and bearings are all stacked with metal spacers, washers & shims. This prevents the bolts from bending when the belts are tensioned and bent bolts equal skewed prints!

The Mk1 was designed with nylon spacers in mind but we faced inaccuracies in them. This is why the current Mk2 versions have metal spacers and washers of various dimensions and within specd' tolerances. This is how we ensure your bearings, 2GT idlers and belts will, and always be aligned.

Optimized Design for Maximum features

your new machine will also have possibly the smallest footprint of an Ender 3 build volume with a CoreXY setup

The machine you will build will also have a small footprint, not much bigger than the original Ender 3 because we managed to keep everything within the CoreXY cubic structure.

Despite having a maximum printable volume of 230x205x400mm (x, y & z) and boasting a synced dual Z axis, the only thing that sits outside the frame is the your filament and the LCD screen. 

Repurposing Your Existing Parts

Build your new machine with existing parts. We know you love your Enders. We do too, so we kept them and made this

The goal of the kit was simple, to design an optimized CoreXY machine re-using as many parts as possible from the Ender 3 so changing to linear rails was definitely out of the question.

Using V-wheels as the linear motion mechanism made absolute sense for us as they're reliable and quiet. Using good linear rails would also cause a severe price hike in the kit and we really want this kit to be as affordable as possible and in all our tests, V-wheels are very good when well tuned!

Future Proofing for the Hotend

a newly designed hotend plate

We completely revamped the original Ender 3's hotend metal plate as we wanted something better. Something more future proof but we also wanted the original fan ducts to fit so we made this. 

This is the KAY3D's hotend plate. Comes with carefully designed holes, the plate fits Creality's MK8 extruder, the hotend fan, it can also fit E3D's newest Hemera/ Hermes with some modification. 

It also has additional M3 holes that are pre-tapped to allow for custom additions such as mounts for the BLtouch, EZabl etc.

Keeping it Flexible. Bowden or Direct Drive Extrusion

KAY3D BMG dual drive extruder

We understand that sometimes, bowden tubes are not everyone's cup of tea as they may lead to under extrusions so we designed an extruder that fits our hotend plate like a glove. To be printed with enough walls and infill, the KAY3D Direct Drive Extruder that utilises BMG's dual geared technology will push through filament like a complete machine.

Say no more to under extrusions and high retractions lengths with the KAY3D Direct Drive Extruder. Pinions, shafts and gears can be purchased separately. 

Downloadable Firmware and Custom Support

kay3d downloadable firmware

We know that firmware modification is not everyone's cup of tea so we're also providing you with the firmware. Choose the right firmware, click & download, flash and done.

Should your choice of motherboard be not supported, our firmware support team will even edit the firmware for you. All these as part of the support you'll be getting when using our CoreXY Conversion Kit.
