Ender 6 fault temps in Heaters Hotend and Bed

@phaedrux Would you mind sharing how you wired the "det" and "pwm" wires from the Ender 6 to the Duet board?
-
@ddrake Do you mean to ask me, or @javcab ?

Not sure which wires those are. Can you elaborate?
-
@phaedrux that was meant for @javcab
Sorry
The "det" one is a 4-wire, which I believe is where the BLTouch, and whatever else is on the breakout board, gets its power from.
The "pwm" wire is a 2-wire, with what looks like a neutral and a 2nd wire.
I can use a meter to see where they actually go, but I'm not sure about where on the Duet they would go. There is literally no information online regarding this.
-
Well if you can identify which wire goes for which piece of hardware we can probably figure out where to plug it in on the Duet based on it's purpose.

Not really sure what I'm looking at. Photo of the actual board for context?
Shared grounds are a bit problematic for the Duet when it comes to fans and heaters because the duet switches the PWM signal on the ground side, so fans and heaters will need their own ground wire. They can share the same supply voltage though as long as it can handle the combined current.
Any signal wires would need to go to the signal pin for that device, endstops, probe trigger signal.
-
Edited: I will upload photos, and re-do my wiring diagram, because it was wrong.
@phaedrux I believe many things in the upper portion, like X and Y endstops, extruder, extruder fan, parts cooling fan, filament runout detector, and BLTouch that have one, all share a common ground.
looks like the BLTouch's yellow and power are tied into the two pwm wires. The yellow, black, and blue wires on the BLTouch are all grounded conductors, but I'm assuming the blue maybe a tx/rx. The filament runout has a power, ground, and a yellow wire, that is also a grounded conductor.
I hope you can help me. Thanks a lot, either way.

Ignore the text
Black and brown are grounds. White is signal for trigger. Red is 5v power in. Yellow is PWM control for pin.
-
@phaedrux That is an older BLTouch. The newer ones have a QR code on the bottom. Mine is v3.1, and is a bit different. I believe the +5v and GND are swapped, and it can also do +3.3v logic automatically, without needing modifications.
The breakout board seems new to the latest versions of the Ender 6, as my breakout board has a date of 3/31/21. I'm still mapping out the connections to the breakout board and the different connections coming out of it, and I'll post what I find, and if I work it out, what the solution is, as nobody seems to want to share what they ended up doing.
-
Yeah proprietary breakout boards are tricky because they often used shared ground which is problematic with electronics that switch on the negative side.
-
@phaedrux I guess I'm giving up. I was hoping someone would share their solution, but I guess it's too much to ask. I'm returning the duet2 wifi, 4.3" paneldue, duex5, and thermocouple boards to Amazon, and I'll just go back to the stock board and flash it with Klipper. Thanks for the help.

Well due to the electrical differences on the ground plane the solution would be re-wiring. There's not really any way around that.
If you got the Duet stuff on amazon it's a clone board by the way.
