When selecting the extruder for the RepRapPro be sure to take a little extra time before just selecting the Mini extruder as I did. My line of though was that it was smaller and would look better on the printer which, looking back on it was a pretty stupid reason to make a section. By and large I consider my selection of the Mini extruder to be my biggest misstate with regard to that printer build. Here is what I’ve fount;
- The mini is really small. it’s small so the gear teeth are small which means your prints need to be dead on. There is no room for even a small deviation.
- The threading channel hole for the plastic is static. Simply put it’s a printed diameter hole. threading and working with it is a pain.
- the Friction adjustment is not really all that effective.
- The mounting of the extruder on the printer itself can effect the friction applied to the plastic being extruded. (Really an pain)
So simply put for me the choice of the Mini extruder was really bad! It’s just my opinion but you’ve been warned, choose the curtain on the left and go with the normal, proven Huxley_Extruder.
in the RepRapPro model files it’s the directory Modified_RepRapPro_Huxley_Extruder not the Mini you want. (Picture on left)
