Sanguinolo 1.3a Wiring Hot End

Postby solodude » Mon Apr 09, 2012 4:09 pm

On my Sanguinololu board I have 4 pins ... How do I wire these 4 pins to my Hot End ?

Thanks for your help...

2 pins are for the thermistor, 2 for the heater (resistor). You need to go to the document site for the board to determine which is which.

You actually have six (6) pins. The four pin header is to provide power to the resistors and the two pin header on the opposite side of the board is for the thermistor.

For details on how to wire your Sanguinololu, see the reprap page and the wiring schematics.

http://reprap.org/wiki/Sanguinololu
http://reprap.org/wiki/Sanguinololu#Wiring_shematics

Note that the four pin header really is only two connections, a pair of pins for each end of the resistors. So if you select the left two they are connected to the same thing and same for the right two. They are ganged up together to provide higher current output.

So I need to run a seperate wire from each end of the resistors to each pin... ? As opposed to joining one side of the resistors together and the other side and running two wires back ?

I had already looked at the Sanguinololu Schematic and information they don't really clarify this...

Hey SD,

You just need to run a two conductor wire from the resistors.
For example I have my resistors running in parallel, hooked up with 18 gauge two conductor wire. Each wire connects to TWO of the four pins. if If you are looking at the board from the side - left two pins ground/V- and the right two are 12v/V+.
The bottom of the board is silk screened with what the pins are.

What do I do with the grounds... Just run extra grounds from my power supply ?
