Hey guys,researching extruders has been fun, but I'm at a standstill on what extruder to use for my kossel mini(750/360)
Hopefully this thread will help other people when they are just starting out as well.
Here are the options I've found:
1.) Johann's extruder - comes with printed parts kit, requires geared stepper motor, slightly pricier, is compact.
2.) Airtripper BSP - takes a regular Nema17 motor, prone to slippage due to using underpowered motor, cheaper than johann's if buying a kit(tridprinting), no hobbed bolt.
3.) RichRap's Geared Bowden Extruder - design based off of Greg's Wade extruder, plastic kit is pretty expensive and less common than the other 2. Uses a standard nema17 with a herringbone, so less prone to slippage than airtripper. Uses standard Wade's hardware(8mm hobbed bolt). Purchasing a kit makes this option more expensive than 2.) But still less than 1.) Otherwise, this is quite a cheap option if you can print parts.
4.) Greg's accessible extruder - as seen on electronhack's YouTube, he uses the accessible extruder for his kossel mini. Making me confused on the difference between 3 and 4.
5.) PG35L microextruder - mounted a small, lightweight direct drive extruder under the kossel mini effector or above on the larger Rostock effector. Removes the need of the Bowden extruder.
Other questions:
1.) Is it better to have a Bowden extruder tube as vertical as possible? I.e. mounting it on top of the kossel?
2.) Is it much more difficult to utilize a larger effector instead of the smaller kossel mini's? Losing x/y?
Thanks for everything!
