The Bowden principle
TheBowden cable lets you reduce the moving mass of the extruder and thusallowing faster controlled motion, less shaking of your machine, lessenergy use and importantly: faster printing! Normally the mechanism thatdrives the filament into the hot end (where it melts) is directly ontop of the extruder. This creates problems of balance and oscillationswith faster motion which you can see in your printing results and hearand feel when your machine is shaking.
Ifthe filament drive mechanism is placed on a non-moving part of the 3Dprinter, it can be pushed into a tube. PTFE is useful becauseit is slippery: it has little friction with the plastic. This limitswear and loss of energy. The tube's other end is connected to theextruder's hot-end.
The concept of using a Bowden cable as guide was suggested and pioneered by Ed Sells.
Features
The inner diameter of the bowden feed mouth is 0.4mm to print with 1.75mm filament.
The J-head is assembled with 100K NTC thermistor and Cartridge heater,NOT heat resistor.
