Ender-3 Pro Upgrade with BLTouch and Direct Drive Extruder
thingiverse
Ender-3 Pro upgrade for direct drive extruder and BLTouch auto leveling, a new trolley was purchased with an extruder mounting bracket. I also purchased a Befenybay direct drive extruder, which came with a shorter (lighter) stepper motor. The original hot end (which came with the Ender-3 Pro) was reused. The extruder mounting bracket needed quite a bit of modification to allow correct alignment of the extruder with the hot end. After cutting away pieces of the extruder mounting bracket, new holes were drilled in the trolley bracket. I attached the two with bolts and nuts. Adding the Sovol Creality Ender 3 Pro 32-bit Silent Board Motherboard V4.2.7 with TMC2225 Driver Marlin 2.0.1 for Ender-3 Pro really makes it quiet and provides connections for the BLTouch. The following video explains modification of the mounting bracket and installation of the BLTouch. Ender-3 Pro Upgrade - Direct Drive Extruder & BLTouch https://youtu.be/xrGZXnIrh7s
