Oh and to let you guys in on what i'm working on... Here's the idea.
I'm working on a system that feeds the filament trough a threaded tube(metal), For this to happen the directional feed of the motor has to change from vertical to horizontal. This is all good until i realised that the feed of M3 thread id 0.5mm per rev and the bolt feeds +/- 25mm.
So i need to either make the motor 50 times faster or find some sort of gear setup that doesnt take up to much space. I have tried worm gears, but the immense torque needed for the gear to drive the worm is not something i want for this system.(they're usually the other way around)
BUT ! here comes the fun part. If this works, you will have absolutely zero slipping because it will be physically impossible to slip through a cm or so of thread. Also this will solve all wear and tear problems with the feeder, as there is no contact with the actual feeder. And it will also be no problem feeding soft filament, because the threads will grip this just as easy as any other filament.
Just a quick rendering and wireframe:
So please share your thoughts and ideas on this, all help is welcome
Rick
