Topic: Filawinder Shield Schematics

I've just build and tested the filastruder and filawinder, with the last firmware also the 3mm filament goes good.. now i want to study the arduino firmware but i can't find the schematics of second board (shield) connected to arduino board..

where a can find it?

thx

.sch and .brd files for the control board and sensor board are on Thingiverse-

Ok, thx

Can i ask you what software are you used for create the schematics?

i'll try to open them with eagle, but i'm curious  to know what are you used for..

Re: Filawinder Shield Schematics

I used Eagle, so they should open with no problem.

Re: Filawinder Shield Schematics

I do not use Eagle, and don't have it installed (nor do I want it).  Would it be possible for you to export the schematic to a pdf and upload that somewhere?

Thanks!

Re: Filawinder Shield Schematics

Hi,
I built the main winder pcb from the page -->http://www.thingiverse.com/thing:174383/#files
I have some questions re. how power is distributed. I want to understand how things should work before I connect power
1) The top copper layer of the pcb is Vcc. This is the +5V generated by the nano from the Vraw +12v fed in on pin6 of H2 (from thiniverse schematics ) Is this correct?
2) Pin 7 of H2 is connected to the center pin of the Power Jack J1. Looking a the videos of filawinder assy I don't see that this jack is used. Instead a 2 pin connector is made to pin 6 and 7 of H2. Whats going on here? Where does the 2 pin connector from pin 6 and 7 go when it leaves the pcb, to what is it connected?
3) Is the only function of the 5 volt regulator 7805 on the pcb to supply +5v to the servo motor?

Re: Filawinder Shield Schematics

The header leads out to the power switch.  The rest is correct.  The VCC plane is fed by the Nano's 5v, and the servo gets its own independent 5v supply so it doesn't try to draw too much current through the Nano.  Also the regulator puts out a reliable 5v while the Nano tends to be closer to 4.8V.
