wooddragon Has anyone build a sensor for this, and what encoder / pulse generator did you use?Thanks...
Repetier <font face="Arial, Verdana">You can get one here;</font><font face="Arial, Verdana">http://sparklab-shop.de/parts/spareparts/28/fts-filament-tracking-system</span></font><br/></div><div><font face="Arial, Verdana"></font><font face="Arial, Verdana">plans are also available for building them on your own.</font>
googliola <font face="Arial, Verdana">Maybe this is a start:</font><font face="Arial, Verdana">http://doku.radds.org/dokumentation/other-electronics/fts-filament-tracking-system/</span></font><br/></div>
CptanPanic Would this work? https://www.toybuilderlabs.com/products/tunell-3d-printer-filament-monitor<br/>
Repetier It is not supported like it is used in Makerbots. We only need a pin toggling between high/low when filament moves. Not knowing this device I can not say if such a pin is available there, but it might be.
CptanPanic That sounds even simpler. So you are saying that we could just a simple rotary encoder, something like https://www.sparkfun.com/products/9117 ? There are also more expensive ones that put out 100+ pulses per rotation.
Repetier Yes, taht would work for the signals. But question is if friction is enough to safely rotate it and if lifetime is long enough. Others use a hall sensor or light sensor to switch such a signal without mechanical parts.
CptanPanic Ok I bought a optical wheel encoder for robot that may be the ticket. It is coming from china so will be a while, but report if it works.
Garremmash if there anyway to invert state of pin? I want to install optical endstop as filament detector, but there is no way to invert signal, and when filament goes through sensor it written that it is filament out
