Duet3 Mini5+ Ethernet Nozzle Distance to PEI sheet is too large
-
@droftarts
Good morning Ian, the ones that were already installed still don't work, they are probably defective. I have now temporarily connected a new 2 euro set and after entering your GCodes the first one lights up red, the second green and the third doesn't light up at all. Power supply via the 5v PWM+, see photo. However, I only measure 3.6 volts on the third LED and after the ground PIN of the LEDs is broken, both of them continue to light up and I measure 5 volts on all LEDs again. So I will use an external power supply.
Which LEDs should I order or can I use the 2 euros?
And please, where can I order connectors for the 1LC board?
Thanks Ian

@Wobi Are the 5V power and GND the Blue and Yellow wires? If so, you've plugged 5V (blue) into 5V_EXT (which should be okay), but the yellow GND wire into 'out6_buff', not GND!
Move the yellow wire to a proper GND pin.

What connectors you need depend on which version of the toolboard you have.
See https://docs.duet3d.com/en/User_manual/Troubleshooting/Parts#connectors-used-on-duet-3-toolboard-1lc
and https://docs.duet3d.com/Duet3D_hardware/Duet_3_family/Duet_3_Toolboard_1LC#description-of-connections
Most likely it is a 3- or 4- pin JST PH. You can find pre-wired ones on eBay that you can solder your wires to, or the crimps and headers ready for crimping.Ian

yes, it's true that it still worked.
Thanks for the links, that helps me.

Hello Ian, thanks to your instructions and tips, I have now connected correctly and all three of the connected LEDs work perfectly. The built-in ones are probably broken.
I have to wait until I have the JST PH connectors to install it.This solved my problem, thank you very much.
Greetings Wolfgang

@Wobi Great! Glad you got it fixed in the end. Are the LEDs wired to the toolboard, or do the wires run back to the Mini 5+?

The LEDs are connected to the Mini5 as described above -
@Wobi Okay. I'll try them on a 1LC when I get a chance, but I think the LEDs will need a level shifter, or 'hack' (I'm waiting for some diodes to be delivered to try this hack) to accept the 3.3V signal they will get from a 1LC io.out pin.
I haven't tested it, but I think the out6_buff pin (pin name
out6) should also be able to drive the LEDs as the data line, instead of DO on the NEOPIXEL header, as it is a 5V PWM pin. If you have wired 5V and GND to that header, it may be convenient for you to connect the LED data line there, too.Ian

Good morning Ian, yes that would be an advantage as only one plug is needed.
But at the moment the LEDs are working perfectly, so there is no need to change them.
Now I need a hood to hide the tangled cables.

@Wobi Hello, may I ask you what mount you are using for the 1LC tool board? If you have a link that would be great. Thanks
