CTC Bizer Filamentspooler Premountmotor

thingiverse

To prevent clogging nozzles because filament pools don't flow easily I have mounted a prespooler motor parallel to the nozzle motor. The resistors in the layout are at least 2W or better 5W wire-cement versions because they get very hot. Rebuild on your own risk, no guarantee of function. It works well at my CTC, but you could instead use a 22R resistor, an 18R resistor, or a 15R resistor to give the nozzle more power. Lower values may disturb the motor driver. The motor holder I have is available for rebuilding. I have updated the parts list and changed the resistor, see FS2_SL_.txt. I have also added a holder for the casing and the step-motor holder with filament leading support. Additionally, to prevent step loss, I have integrated under the step-motor pressure box a spring holder system that presses the box onto the step-motor pinch wheel. Now it works much better. Don't tighten firmly the box screws; just tighten them slightly so the spring can work.
