Extra Neopixel LED string next to Stealthburner LEDs from Octopus 1.1 board

Buurman · May 25, 2022

Just sharing in case it helps someone, can verify that it works.

I wanted to have strings of neopixel leds in the chamber, but already having 3 wires going from the board to the Stealthburner (by default) makes is hard to make a serial string of LEDS.
These are connected on the default controller (neopixel) PB0.

So I started looking for an alternative, on the board is a dedicated BLTouch 5 pin connector (right top) and I used this to power 60 leds (yes its a lot)

The pin I used is the PB06 and the 5V and GRD next to it on the same connector.
Just add the new string to your config (copy and make up a new name) and you are ready to go.

Printer.cfg

#####################
#### LED LIGHTS #####
#####################
[neopixel neo]
pin: PB0
chain_count: 4
#   The number of Neopixel chips that are "daisy chained" to the
#   provided pin. The default is 1 (which indicates only a single
#   Neopixel is connected to the pin).
color_order: GRBW
#   Set the pixel order required by the LED hardware. Options are GRB,
#   RGB, GRBW, or RGBW. The default is GRB.
initial_RED: 0.0
initial_GREEN: 0.0
initial_BLUE: 0.0
initial_WHITE: 0.0
#   Sets the initial LED color of the Neopixel. Each value should be
#   between 0.0 and 1.0. The WHITE option is only available on RGBW
#   LEDs. The default for each color is 0.

Macro for turning them on/off: (and colors, and other freaky things, but I kept it simple for now)

[gcode_macro SB_LED_ON]
gcode:
  SET_LED LED=neo RED=1 GREEN=1 BLUE=1

[gcode_macro CHAMBER_LED_ON]
gcode:
  SET_LED LED=chamber RED=1 GREEN=1 BLUE=1

[gcode_macro SB_LED_OFF]
gcode:
  SET_LED LED=neo RED=0 GREEN=0 BLUE=0

[gcode_macro CHAMBER_LED_OFF]
gcode:
  SET_LED LED=chamber RED=0 GREEN=0 BLUE=0

Feel free to respond with freaky LED effects

Good tip. Anyway, ok you asked for it: https://github.com/claudermilk/TridentBackup/blob/aef1559d1ef62d692b05ef0560f34585de7e1da4/leds.cfg

I use the julianschill led_effects library (here: https://github.com/julianschill/klipper-led_effect).

First link isnt working for me, but yes, I know this one, pretty cool, but a bit too much disco for my printer.. but I like my startup sequence....

And going full blue as a color.. looks pretty cool if you ask me..

claudermilk · May 26, 2022

Huh, let's try this one: https://github.com/claudermilk/TridentBackup/blob/master/leds.cfg

(ok, seems to be working)

Dang, those green parts are BRIGHT under the LEDs.

Buurman · May 27, 2022

I dont know why.... both on my phone and desktop... 404 error from Github...

Yup, NEON Yellow part are pretty nice under pure blue lights, yet.. with printing black parts, not that great

Well, I clearly don't understand how to share files from my Github.

So, let's just dump the file here. I'll hide it behind a spoiler since it's kind of long.

Oooooh, you are making me curious.... after I finish printing my second voron parts I will give it a try!

Check your github profile. I suspect that the TridentBackup is private to your account. From an outside viewer, you only have two public folders and they are SmartThings related.

Aha. That took some digging, it should be visible now. I didn't anticipate sharing it with anyone when I set it up.

JesNoFear · September 20, 2022

Has anyone programmed or found a fade command? not one that loops (breath).

claudermilk · September 20, 2022

Looking at the docs here: https://github.com/julianschill/klipper-led_effect/blob/master/docs/LED_Effect.md

I see this section that looks like it's what you are looking for:

Quote

Fading in and out

Effects can be faded in and out by specifying the FADETIME parameter: SET_LED_EFFECT EFFECT=panel_idle FADETIME=1.0 fades the effect in during one second. Running SET_LED_EFFECT EFFECT=panel_idle STOP=1 FADETIME=1.0 fades it out in one second. We can also fade out all effects by running STOP_LED_EFFECTS FADETIME=1.0. It is also possible to crossfade effects by running a fade in command and a fade out command successively.

JesNoFear · September 23, 2022

Thank you, that is exactly what I was looking for.

ludwig100 · January 19, 2023

Hi. Im trying to use the caselight_led.cfg but get this error. I added [include caselight_led.cfg] in the printer.cfg.
I cannot figure out what is wrong.

claudermilk · January 20, 2023

Double check your syntax in the definition the error is pointing to. Something is entered incorrect there. If you need help, post that snippet here.

Oh, and welcome to the forum. If you like, head over to the Introductions forum to say hi to the forum.

Hawkeye · July 6, 2023

Is there any other pin I can use for RGBW (Stealthburner) as PB0 is used for my case and i managed to let the smoke out of PB6?
