I will be converting a Sigma shortly and the only part I'm not sure of is if I can use the led strips?
Here's the connection on the Sigmas board
Is it possible using the wifi and the duex?
The PWM outputs on the Duex can drive LEDs. I would need a little more info on what the LED circuit on the SiGMA was to comment on how to connect them. Also what does the Sigma indicate with these?
To be honest I'm not sure. I've found this https://raw.githubusercontent.com/BCN3D/BCN3DSigma-Process/master/Product%20Sheets/FP10870%20-%20LED.pdf
The LEDs generally just stay white. In the source code I can see them reference the LEDs but I presume they've not managed to do much with them.
Looks like 24V led strip so powerring them evenly makes white, varying the amount allows you to shift the colour.
You can set it up to be red on heating, white on printing green on done… If you wanted
Ok cool but I'm still unsure on how to wire them. Looks like the white wire is the constant 24v.
So connect white to +VIN (assuming your VIN is 24V) and connect the RGB wires to the negative sides of 3 of the fan outputs on the DueX5.
Awesome just as I thought Thankyou!
Works a treat
good stuff - disco printing

sorry need more explanation on the wiring please.
where do the RGB wires go? I see there are FAN3,4,5,6,7 on the duex5
I was able to configure those fans to 12v internal since my RGB led will be 12v
