Update:
The 100k thermistor for the bed is off at the higher temperatures. The thermistor reads 80c when bed temperature is actually 90c. No big deal if I don't forget about it, Have done the final cal on the stepper travel and am getting some very nice prints.

Hi Kieth and Chris,

Would you please help me with following three questions:
1. To install opto end stop on ramps.
Do I use 220r resistor?
Do I use the resistor only on Vcc(anode +),
Or I use three resistor for each of anode, ground, and collector?
2. For the power supply of Da VInci,
I see so many wires for 12v, 5v, 3v on two different connectors.
I don't know which color wires goes to positive, which goes negative of ramps.
3. On led, do I use 220r resistor?
Do I use resistor on negative? Or all three of them?
Where can I connect these wires to on ramps? The 12v fan connector?
Thank you for your help.

Hi Kieth and Chris,

Would you please help me with following three questions:
1. To install opto end stop on ramps.

I couldn't get the optical end stops to work. My options were to get new optical or mechanical end stops with the pcb on them orlearn how to build my own pcb with the resistors. There are others on this forum that can answer this way better than me.

Do I use 220r resistor?
Do I use the resistor only on Vcc(anode +),
Or I use three resistor for each of anode, ground, and collector?
2. For the power supply of Da VInci,
I see so many wires for 12v, 5v, 3v on two different connectors.
I don't know which color wires goes to positive, which goes negative of ramps.

I used both plugs with yellow and black wires. They are both 12v dc

3. On led, do I use 220r resistor?
Do I use resistor on negative? Or all three of them?
Where can I connect these wires to on ramps? The 12v fan connector?

I used a 220 ohm resistor on the LED which bypasses the circuitry on the led strip. I did this because 12 volts is too much for the LED and they get extremely hot. If you can find a 5 volt or 8 volt wires on the Davinci power supply you might be able to use those, other wise I used the two small positive and negative contacts on the ramps board next to the power connections. Here is a picture of the connection points from another post.

D9 on the ramps board is supposed to be for the fan

Thank you for your help.

You can see in this picture how I wired the led strip.
I basically bridged the resistors on the strip for one end of the resistor and the other end is soldered to the incoming terminals.

Thank you Chris..

Now I understand..
For the power part, I see connectors with two yellow wires, and two black wires.
Top connector:

Yellow - 12v - goes to + for the ramps
Black - gnd - goes to - for the ramps.
Yellow - 12v - goes to + for the ramps
Black - gnd - goes to - for the ramps.
Bottom Connector:
Black - gnd
orange-3.3v
red-5v
yellow-12v
So I assume the theory, correct me if I'm wrong:
If I like to use the 5v power,
I just connect the positive into the 5v red wire, while the negative wire connect to the gnd black wire of bottom connector.

For the image of led strap, I can't see very clearly, did you bridge one positive and negative on one side of resistor, while the other side of resistor is soldering onto the negative.

I did not use any wires on the Davinci power supply except for the yellow and black 12 volt wires so I am not sure what the voltage is for the other wires..
Here is a better explanation of the connections to the LED strip. Only two connection points for 12v power on the right and connect the two traces on the left at the small resistors and connect the 220 ohm resistor on the negative side at the "power in" and at the two connected traces.

Dear Chris,

Thank you for all your help.
I decided to use mechanical endstop like you..
And I made this, Adjustable Position Z Endstop Holder" hope it could find some help for you.

It's amazing how quiet the motors get with ramps.

It depends on the voltage going to the steppers. It is adjusted on the stepper driver boards with a small pot.

I will solder some wires to the ramps stepper controllers, and put them in my davinci motherboard, so i can adjust the currents. My feeling is they are way to high, especialy for the slow movements of the Davinci.
