ENDER 3 NG v1.2 - coreXY conversion

E3NG / Ender 3 NG

version 1.2

!CAUTION! Reprint and replace the electronics_DIN_rail_PSU_24V.stl from the bacpack + electronics folder if you already have the older version. The old design can in extreme cases cause the mounting screws short the 24V line on the PSU to the ground.

CHANGELOG:

2025.06.29 - Small update to the 4010 fanducts (toolhead - cooling) to properly fit both Creality and Jiesammy (Funssor kit) 4010 radial fans.

2025.06.15 - Updated file frame_bottom_rear_z_lower_triple.stl to have more belt clearance with simgle Z motor setup.

2025.06.05 - Significantly improved the under-bed fan performance for the stock carriage by adding a file bed_fan_6015_01b.stl - just print and install it into the under-bed fan housing if you are using it.

2025.02.08 - Increased the gap between supports for 5015 fanducts as with certain layer height combination, slicer ignored the gap and fused the supports with the part.

2025.01.16 - FANDUCTS OPTIMISATION!! All sizes of 4010, 4020 and 5015 fanducts have been completely redesigned. I have used CFD analysis for each version to optimise the design and to make sure the air stream is directed where it should be. There is now 1mm clearance between the fanducts and the build plate for each size, the opening for heatblock is slightly bigger and I verified that it fits with all the compatible hotends!

2025.01.16 - Updated build guide - changelog on the website.

2025.01.03 - Updated electronics_DIN_rail_PSU_24V.stl in the bacpack + electronics folder.

2024.10.30 - Build guide released (on the website)

2024.08.16 + Electronics panel for dual color printing incl. hexagons - folder EXTRAS

2024.08.14 - Initial v1.2 release
