Welcome back to Aurora Tech Channel.
In my previous video, I upgraded my Ender-3 Pro to have a dual Z-Axis, a dual gear extruder, and a Capricorn bowden tube. It works pretty well compared to the stock Ender-3. The Bowden setup does have its limitations, like how it can’t print flexible filament like TPU. Furthermore, when I print something like this Eiffel tower, it can’t handle the crazy amount of retractions and the model does not look good.
I also tried the Creality direct-drive upgrade kit. It improved a little, but the weight of the stepper motor is a problem. Another problem is that it just came with the standard single gear extruder which is the same as the stock one. I’ve always been trying to find a high-quality direct drive setup for the Ender-3. It has to be lightweight but powerful enough to push and retract the filament and deliver a better print quality.
Today, I will test this OMG DM1 Extruder by My3D. This thing is not cheap, it costs $85. It’s compatible with MK8 and E3D V6 hotends. You can install it as a Bowden setup or direct drive. It came with a Japanese brand ASPINA mini stepper motor. The weight of the motor is around 94 grams and the extruder is around 65 grams, so the total weight we add to the hotend will be just around 160 grams. You also don’t need to 3D print another mount to fix it on the X-carriage, it screws directly to the hotend. The dual gear inside the extruder actually works like 2 extruders. It looks like a well-engineered extruder. I will assemble and install it on this Ender-3 Pro and see what kind of print quality we can get.
