Ender-3-Mods-Collection

This is a collection of my personal Ender-3 mods.

Added a second Z-Axis:

Some mods are dependent on:
https://www.thingiverse.com/thing:3688967 (Ender 3 all in one rear mount kit by TeachingTech)
https://www.thingiverse.com/thing:2920060 (Cable Chain by johnniewiskey, included as an FreeCad arrangement)
https://www.thingiverse.com/thing:3319649 (X belt tensioner, a streched version of the base part is in my files to be used with the direct extruder, which frees about 2 cm of the belt, just thow away the nuts, they interfere with the new z-axis slider)

Nice to haves:
https://www.thingiverse.com/thing:3372977 (Ender 3 Double Drawer, one regular, one mirrored, need to cut of 0.5 mm in the middle where thay both touch each other)

Additionally, I replaced the original Ender 3 controller by some BIGTREETECH SKR 1.4 Turbo (+TMC2130 stepper drivers + TFT32 touch) paired with an Raspberry Pi 3 B running Octoprint.

Here is the shopping cart for all my mods:

I bought the direct Extruder kit here:

The SKR 1.4 was this:

If you plan to use E1 as the stepper output for the second Z-Axis, you should also add another end stop switch like this:

Coming soon: Adding an end stop for Z2 and adjust Marlin to use E1 as the driver for Z2.

You can find Marlin for SKR 1.4 with follwing settings

• Dual LCD (CR-10 + TFT35 touch)
• Ender 3 specials
• EEPROM SD-Card file emulation
• Corrected extrusion constant
• …
