Missing Wiring harness Instructions for Ender 3 v2 #11

Open bsinger99 opened 2 years ago

bsinger99 commented 2 years ago

Hi! I recently purchased a Hermit Crab & an H2 extruder for my Ender 3 v2. I'm having a problem determining how to connect the Hermit Crab to my 4.2.7 motherboard. The provided wiring harness has several unlabeled connectors and at least two (FLD & EO) which I haven't been able to determine what those acronyms refer to.

Also, the concern is that the manual has a picture of the PCB board interfaces connector wiring which doesn't match mine. The PCB-F illustration indicates that the BL TOUCH connector connects with the orange wire on the outside - mine connects with the orange wire at the other end. (Possibly it's just a mistake in the picture?)

Are there any instructions or a resource you can refer me to help me out?

They haven't provided instructions on how to connect them to their own printers never mind 3rd parties

FLD = filament detection (u can use a BTT smart filament detector E0 = Extruder motor the black and red floating wires are the extruder heater

I know this is a year old but how do you use the smart sensor looking for a replacement cable and haven't found. Or do I have to learn to crimp those micro connectors. Which is fine I just have any of them in stock.

Also on the hermit crab wiring harness it has a 3 jst for the fld and a single wire for with a Dupont on it. Where does that go since the just just goes as a limit switch for extruder.
