How to control the LED-PWM Outlet at UO+


Recommended Posts

Posted · How to control the LED-PWM Outlet at UO+

Hi Guys,

I would like to connect an LED-strip to the LED-PWM outlet of my mainboard.

I'm using a newly assembled Ultimaker Original+.

It's the red-marked port at the below picture, I'm talking about:

I just checked the output and it seems, the port is low by default. I measure 1.0-1.3V (digital instrument).

So how ist the outlet controlled? There is no function at the Ulticontroller as far as I can tell. How do I get current to that port?

Regards Uwe

    You should use @amedee firmware for that, it adds led control on the panel control and it even saves the brightness so when you turn it on it lights on like a um2.

    Thanks for that,

    one question still: When I start the firmware-builder and choose the Ultimaker Original+ printer, I get a lot of alternatives to change in the lines below, but I can't find an LED option to choose!

    Is the LED-option built into the generator as standard?

    Indeed. If you just choose umo+ without changing anything you get an standard umo+ firmware, but with added Led pwm control

    Yes indeed there are very few things you can't opt-out, mostly bug fixes. Led control is one of them.

    I should probably document that as I tend to claim that without any option it is the same as the official firmware, but it is not 100% true anymore.

    Indeed. Is better.

    Thanks for clarifying that.

    I finally took a different path though. As my LED-stripes turned out to be 12V, I had to use some hardware (LM7812) to adapt it anyway. So I connected it to VCC2 (+24V) at Pin1/J15 (PWM/LED) and to GND /-24V at Pin3/J9. Both pins were unused at my board and easy to access. I use a little switch to control the lights.

    Have a nice sunday,

    Uwe
