That worked for part fan, hotend fan is still not working for some reason. I also have dual extrusion. The only change i made was adding H1:2

EDIT: ah nevermind, im dumb. I had the fan plugged into the fan2 the entire time
I am trying to setup the Adafruit LIS3DH Accelerometer with no luck so far. I have the Duet2 Wifi. I think that it is connected, light is on, and i didn't get an error in the log for it not being able to connect, but I am not getting any data. I am getting a drive error in the log:
@alankilian Yeah it didn't work. I will order the 74HCT08 and try again
@alankilian i went through the comments but I don't see a schematic
are you saying i need to put both 3.3v and pin 5 into the LV pin on the level shifter? because i currently have pin 5 > lv > hv> LEDs
The ground goes from the duet > ground on the level shifter > ground on the strip
GND from pin 2 on CONN_LCD > GND on the level shifter > into the GND on the neopixel
Pin 5 on CONN LCD > LV3 on level shifter > DI on neopixel
5v from duet > into 5v on neopixel
@dc42 So i tried today to wire it up, but no luck. I use this level shifter: https://www.amazon.com/gp/product/B07LG646VS/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1
is this incompatible?
Hi, this is working great for me, but is there a way to make it poll for 2 duet boards? I have two printers I would like to use it on.
@dc42 Thanks, I see it now. i will try it out 
Is the limit 80 LEDs on the Duet 2? With external power?
On the release notes for 3.3.0, I see the following support was added for the Duet 2 WiFi:
RGBW NeoPixels LED strips are supported
Bit-banged NeoPixel LED strips are supported on Duet WiFi/Ethernet. On these boards RRF will wait stop movement while updating the LED strip, so M150 commands should not be issued while the machine is printing, other than at places where a short pause is acceptable such as at layer change and in the start and end scripts.
What pins are used / how can I set this up on my Duet 2 WiFi boards? I did not see any further instruction for wiring anywhere on the wiki for the duet 2.
@dc42 I do have a PanelDue 5" display, but i dont have anything on stepper 10/11. so do I just need to use pin 5? what fw config changes are required?
@thebaseddoge said in Software package 3.3beta3 released:
@phaedrux Right, but this line in the 3.3beta3 changelog implies that Duet 2 can now do it. That is where my confusion comes from.

@droftarts said in Software package 3.3beta3 released:
@thebaseddoge I think a pin has been enabled for controlling the Neopixels on 12864 displays. But I don’t know if it works outside this use case. Will need some @dc42 guidance.

@dc42 do you have any more info on this? thank you!
