Features: The Bowden cable lets you reduce the moving mass of the extruder and thus allowing faster controlled motion, less shaking of your machine, less energy use andimportantly: faster printing! Normally the mechanism that drives the filament into the hot end (where it melts) is directly on top of the extruder. This creates problems of balance and oscillations with faster motion which you can see in your printing results and hear and feel when your machine is shaking. If the filament drive mechanism is placed on a non-moving part of the 3D printer, it can be pushed into a tube. PTFE (Teflon) is useful because it is slippery: it has little friction with the plastic.This limits wear and loss of energy. The tube's other end is connected to the extruder's hot-end. The concept of using a Bowden cable as guide was suggested and pioneered by Ed Sells. The main advantages: All metal enables working with Polycarbonate up to 300 degrees Celsius and with future materials that require higher working temperatures beyond those supportedby plastic extruders and hot end. Tested with PLA, ABS, polycarbonate, nylon and PVA.

Buyers are advised that due to skills of user is involved in assembly it is not guaranteed every kit will end up being a working device. But we will make as much efforts as we can to approach that goal. When soldering the SMDs, the temperature can not too high, otherwise there is the risk of bad soldering. Please note that the direction of LED, LED long legs for the positive. The second digital tube's point is in the bottom, is different with the other three points. RT1 is a thermistor, RL1 is a photosensitive resistor. And the length of the pin should be enough to extend out of the shell. The speaker is connected to the O1 and O2 of the voice module and is glued to the lower right corner of the circuit board with a double-sided adhesive tape. Please be sure to finish soldering the back side of the components and then soldering the digital tube.
