Ender3000 is a custom printer, built out of the carcasses of two unused Ender3s. It's an IDEX (Independent Dual EXtruder) printer, allowing for printing with multiple materials, for example dual colour, support material, etc. | Ender3000 is a custom printer, built out of the carcasses of two unused Ender3s.

This build was assembled from the lab's 2 Ender-3s. These printers were donated in 2023, and sat unused for years. Only 2 members ever reporting successful printing, and they were slower, smaller, and more painful to use than any of the lab's other printers, so they really had no reason to exist. | |||
The intent of this build was to dispose these Ender-3s, while offering some new capability to the lab that other printers did not offer. In addition, the goal was to reuse as many parts from the ender3 as possible, without introducing additional external components or costs. In total, this was accomplished with only: | |||
* Raspberry Pi 3 (which was already associated with the original Ender-3s for octopi) | |||
* 2GT belt from amazon ( About $10 ) for the longer axis | |||
* Spare 20x20 and 20x40 extrusion that's been sitting around the shop for years | |||
* The two Ender 3s, and any existing upgrades associated with the E3s ( BL-touch knockoff, glass bed, etc.) | |||

The ender3 v1.1.4 boards use a CH340G; which is a cheap USB to serial adapter. These do not have a serial number associated with them, so they appear identical to the host computer. For this reason, it's important to keep them in the same USB ports in the same order, as /dev/serial/by-path/ is the only good way to consistently send the commands to the right MCU. (If the MCUs get swapped, it will try to home the wrong motors as X, which could be very bad. ) | The ender3 v1.1.4 boards use a CH340G; which is a cheap USB to serial adapter.

Prusa-Slicer seems to be the slicer which currently offers the best IDEX/Multi Toolhead support. A profile has been built off it's existing Ender 3 profile, but with additional configuration of the second toolhead, and start/toolchange GCode to support the IDEX modes, heaters, etc. | |||
