how to use the bare conductive paste

hello, i am doing a 3D printer and i want to use the bare conductive paste for the additional dispenser unit. i tried to use the conductive paste on a paper to test whether it can work or not or it can glow the LED.
also try to glow the directly with the battery it was glowing. so please let me know how to use the bare conductive paste.
thank you very much.

so, what I think you are wanting to do is have a normal plastic extruder AND the conductive paste extruder. Correct? Regardless, we need more information, such as board type and firmware. It will not be that hard to do, just set up as a secondary extruder with no heater or thermistor (I think). You could look into people who have done chocolate extruders as it is almost identical mechanically.

If you need some help, or don't understand what I just said, feel free to send me a PM anytime

Thank you very much for the reply.
I saw the video on the internet for use of bare conductive electrical paint. it looks simple as that we can try it on the paper to draw a circuit with the electrical paint. i tried the same thing on the paper but it doesn't work at all.
moreover i want to run the 5th motor for the dispenser without using the heater and thermistor so what changes do i need to make in marlin firmware for the same. please let me know asap.
Thank you very much.
