Hi,
The opto endstops just supplied in my kit arent working.
Everything is connected ok. When on and connected there is 6.5 volts on the vcc/gnd.
Without any connection there is 12 volt on the main board. The green led lights up and stays on.
If I pass a black object between the sensor groove, nothing happens. All three sensors are the same.
Is this a problem and how do I test the sensor, how do I test the main board output.
Please help.

Hi, please look very good at the optosensors. There are different types deliverd. According the manual you should connect the wires in order: Red, Black, Yellow. But i know there are sensors where the signal is in the middle. See attatched picture, thats the one from the manual. I don't have picture from the other type optosensors, i can post them by monday.
Wires at the optosensors should be connected like this:
red at VCC
black at GND
yellow at SIG

Hi nosomis,
The led on the pcb of the opto-sensors should burn very dim. This is because the circuit on the opto-sensor itself is also present at the electronics board. So the power is distributed over two leds instead of one. We did this, because we wanted to eliminate the pcb board of the opto-sensor, but unfortunately due to lack of time, we still use this solution.

I had the same problem and have changed the wires around. All the wires to the sensors look OK at both ends.
However I still have odd behaviour.
The sensors are either getting 3 or 9 volts.
For the ones that get 9 volts, the LED on the main board is unlit and the LED on the sensor is lit. If I put something in the sensor, the light remain the same.
For the ones with 3 volts the LED on the main board is lit and the sensor LED is unlit. If I put something in the sensor the LED on the main board will go out (the LED on the sensor remain unlit).
Also I can move all my motors in only one direction.
Any ideas?
Thanks.

So the main board is still a problem. I have powered the sensors from the main fan power supply.
I also had to buy new optical sensors, de-solder the old ones and solder in new ones. Seems that the voltage problem on the main board caused the optical sensors to die.
