Ender 3 V2 CoreXY (2nd Gen)

Hello E3V2 CoreXY fellow, 

I’m introducing the 2nd generation of Ender 3 V2 CoreXY conversion kit series, which is now available in a bigger frame and has two Z axis variations (TripleZ or Belt drive). Now the printer has a bigger frame (core +33%) and you can experience the difference with that exchange functionality. More place is available for extruder and hotend (including the original Ender3 V2 tool head) and we keep the possibility of converting back the original Ender 3 V2 .

Notice: Thanks to our community member Chris Barwick for His mod, the conversion kit is now also compatible with the Ender 3 (V1/Pro).

The major improvement from the first generation was integrate external components directly into the frame by only re-using more already available parts from the original Ender 3 V2 and reduce some costly parts that had to be acquired without compromising quality and speed.

                                                         [chart update 2023.dec.23]

Furthermore based on you feedback we’ve also made enhancement on the YX and Z axis to make it more firmer and we improve cable management for a more clean look. last but not least, thanks to Our Community  the new Triple Z axis is available.

Now two options are now available for the Z-axis:

• Triple Z Option: New option for those who prefer the high accuracy and positional repeatability thank to our new axis.
• Belt option: For those who want to make some experiment with belt system (note: I recommend only this option for those who have a stronger stepper motor.)
   

As a reminder one of the advantages of the CoreXY system is that your Ender 3 v2 doesn’t have to move the heavy glass plate anymore, so by addressing this problem, you can start to increase the printing speed with less impact on print quality.
 

build volume of 220 x 220 x 250 mm

Printer dimensions: 

• without enclosure:  L: 425mm W: 330mm H: 427mm 
• with enclosure:         L:439 mm W: 351mm  H: 567mm

Print Speed: 180mm/s (@ 0,2mm layer, 0,4mm width and with normal temperature) for Pheatus Dragon NF hotend and 85mm/s if you are using stock hotend. 

Can it go faster? Based on my short test, the stock E3V2 stepper motor can hold up to 240mm/s. However, my Pheatus Dragon NF hotend has the best result at 180mm/s due to its maximum flow capacity. If you want to print even faster, consider installing a hotend with a higher polymer volume flow. This will allow you to achieve even higher speeds.
but keep in mind that Prusa PLA filament is certified up to of 200mm/s and Bambu PLA as up to of 300mm/s. over those number is more likely that the speed is only use for traveling.

This project took me another years to finish and I would like to thank you everyone for your support, feedback and your patience. I’m sharing with you all STL, bom list to build this CoreXY machine.

Updates:

• 2nd GEN of Ender 3 V2 CoreXY is now compatible with Ender V1/Pro 
• Enclosure is available.
• Step draw are available for TripleZ and ZBelt 
• Led Top head was added
• Dual Z is now updated to Triple Z axis
• Toolheads catalogue uploaded (see Other Files PDF)

Before you start this project I would like to highlight some details about this conversion:

Several steps require modification of original parts like wiring electric components, drilling holes and threads tapping and those changes require a level of expertise.

Keep in mind that the consequence mentioned in the first paragraph is that you will lose the original machine warranty.

I personally suggest this project for those people who have a good understanding on 3D printing working principle and working.
