    LEDs to light up the nozzle ???

    I have a CR10s PRO and I thought I had fastened ALL screws but ... oh, I missed the one holding the spring loaded lever for the filament feeder !

    Now that I have a breakdown and the X-grantry apart because of loose screws all over I want to design a frame/brachet to hold 4 LEDs nearby the nozzle so I can see what's going on there especially at the first layer.

    I can see there is some un-used sockets at the plug board behind where the ribbon cable is pligged in.

    I plan to use 4 LEDs with a current use of less than 100mA placed near/around the nozzle.

    Could I just switch them into the circuit with the constant running blower or should I make a separate cable )and then maybe a ON/OFF switch) ?

    Any of you have experience, maybe even made light down there ?

    yes sure, you can do that as the CR 10s Pro takes around 480W supply in general and people run Creality printers in 350W supplies, If you atttach 4 LEDs extra of 20W, It won't hurt much, I guess.

    OK, now we're talking ... is it a CR10s PRO and did they succeed ... if so, then I really want to see the result

    - - - - - - - - - -

    Now I got 4 white LEDs mounted in a printed bracket around the nozzle, driven by a constant current sink 20mA and cable along the filament hose to an external power - it works nicely !

    Now I just need to find a method to get the cable from the gantry to the base box and there find a power source.
