Duender — two Ender 3s into a CoreXY

In-progress conversion. NylonG/PCTG parts printed, both printers disassembled, extrusion frame going up.

Duender frame

Duender is a CoreXY conversion that uses two Creality Ender 3 machines. One donor was an Ender 3 Pro, so an aluminum profile did not match. I ordered a slightly longer extrusion, marked the cut from the second machine, and will cut metal in one session with other stock.

Extra holes in the extruder mounting plate are already cut. Drill guides, motor holders, and electronics boxes are printed. Klipper configs for the conversion live with the print files.
