This MK8 extruder is an open source universal suitable for most RepRap and DIY long distance feeding filament 3D Printers.
We have made the NEMA 17 Stepper motor with 4 wires which is specially designed for 3D Printer Controller RAMPS 1.4, so you just need to plug it in, and there you go! no need to buy from others and waste a lot of time trying to figure out how to connect them.
The extruder is almost the most important part for 3D printer, also the most difficult part to calibrate. we have made all metal design to replace plastic parts bowden extruder.
(1) Compatible with ABS and PLA 1.75mm. (2) NEMA 17 Stepper motor is included in this transaction.
While using with PLA filament, please always remember to keep the fan on, otherwise it might get jammed and ruin the hotend. PLA is more easier to get jammed, so it might require some patience to practice. For ABS, we would also suggest to keep the fan on, as this is also better. also remember to purchase filament from good reputation seller, as the filament is very important!

I have used a few different v6 clones and find this one to be the best of the clones I have used.. it's a bit longer then the real e3d but for my homemade printer it works great.. they also have awesome costumer support. .. ordering another right now for my 2nd scratch buit printer....
I ordered 2 of these to compliment the one that came with their Kossel Mini kit. They work, but they're not the best, and I'm not sure how adaptable the extruder is to a different drive gear.
I use Tatsu v2's in my other printers, and their power is second to none. The drive gears here are cylindrical without a hobb, while the idler bearing provides the groove to keep the filament in place. I feel this arrangement is less effective than a hobbed drive gear, as is evidenced by the fact my extruders have been slipping against the filament, shaving it down, causing errors and artifacts in my prints.
I've adjusted the pressure screw, but even at maximum pressure, my filament gets shaved. I've experimented with firmware settings, motor current, idler pressure, potential clogs, everything I can think of. At first, I believed the problem to be caused by an undersized nozzle Sintron provided, but even after swapping it with a 0.8mm nozzle direct from E3D, the...
Pros: Solid and proven design at a great price.
Cons: The unit I received had two separate issues that ended up costing me many hours of assembly, diagnosing, and disassembly. The first issue that I had was that the one of the fan leads broke at the solder joint. Looking at them more closely, the wire gauge is so small that it appears under-designed for handling, installation and operation in a kinematic environment. The irony here is that in the description it mentions that keeping the fan running is critical to prevent the hotend from getting jammed or being ruined, which is precisely what happened. The second issue I had was with a faulty thermistor. Unfortunately it wasn't flat out broken, which would have given an error but gave erratic readings which fooled the controller that everything was running well. This caused erratic extrusion where I could sometimes extrude filament and then suddenly I couldn't and the gear started stripping the filament...
