Setup Skrat No Power light

Hey i try to Install the skrat on my Ender 3 v2 neo.

Well i have plugged everything in it does start and have some Power because the Power LED and the Status Led flash Up shortly.

But after that i Just have a blue Led near the Fan ports on.

Current idear:
Something is wrong that the Board Go in protection Mode and Cut Power but i dont really find the cause of it.
Any idears are appreciated

Oh hey thank you for you answer.

I found Out that its aactually a protection from the Board.
Looks Like the CR Touch is connected wrongly.

IT did Boot Up but i need to compare the CR Touch Pin Out with the Board Pin Out because i used the bl Touch pinout that we're provided in the docs

ah that usually means you have bridged signal to vin

Something like this defenetly but i sewrched online for a good Pin Out of the CR Touch on how to Connect.

Currently i Had No luck.
~
IT could be one of the simple soldering Points that didnt worked so i ordered a crimping Tool now.
~
But that still doesnt Help with the pinout of the crtouch

No clue how i Connect IT the right way

Felix✨Chaos✨OP•11/5/23, 11:12 AM

Small Update.
All soldering Points are good.
Means Something is wrong with the Order of the cables

Means i need to get a good CR Touch pinout or find a more Common Board with the Same pinout than the skrat so i May get some Help from a Reddit Post or so

The BLTouch header is the same order on all BTT boards including the SKRat.

miklschmidt•11/5/23, 11:57 AM

However the SKRat does not have a bltouch header.

miklschmidt•11/5/23, 11:57 AM

So, i'm not sure how you're connecting it. There's no "standard" way.

Felix✨Chaos✨OP•11/5/23, 12:00 PM

There is actually.
The normal bl Touch have 2 cables that would fit the skrat.

I had a skr Mini and it have have a crtouch Port (AS far AS i know you even need to modify the bltouch Pins to use IT in the skr Mini v3.)

But i used the normal CR Touch Order and Backward and IT didnt Boot.
So that a Bit weird but i try it again later

The normal bl Touch have 2 cables that would fit the skrat.

It's not that simple. None of the SKRat JST's are made with the bltouch pinout in mind.

miklschmidt•11/5/23, 3:27 PM

It's not weird at all. You need to 2 gpio's on the bltouch/crtouch (sensor and control) The rest is 5v and 2x gnd.

miklschmidt•11/5/23, 3:28 PM

You can fashion jst's for that. But you can't just plug random wires in random headers and expect it to work

miklschmidt•11/5/23, 3:30 PM

In short, you need the pinout of the ports you intend to use on the SKRat, and the pinout of the CR Touch. Then match the pins in your cable.

miklschmidt•11/5/23, 3:31 PM

after having powered it up once with the wrong connections, there's a risk you damaged either the board or the CR touch.

Felix✨Chaos✨OP•11/5/23, 3:32 PM

I say that the crtouch pinout is wierd.
I didnt connected them randomly too.

I tried the bltouch pinout provided by the Docs.
None other.

The Board does Boot normally when the CR Touch isnt connected

Felix✨Chaos✨OP•11/5/23, 3:36 PM

Jeah exactly.
Problem is that the color sheme between CR and bl Touch is different.

There is No clear pinout for the crtouch (atleast None that i found)

Now im kinda confused which Pin/cable Go where because the bltouch pinout dont work

Felix✨Chaos✨OP•11/5/23, 5:01 PM

Thats the Problem rn

Total Chaos between CR and bl touch

God, those colors defy all logic..

Well, according to the Creality board it seems that:
White -> GND
Black -> 5V
Yellow -> Sensor
Red -> GND
Blue -> Control

Basically they live in upside down land.

Felix✨Chaos✨OP•11/6/23, 7:51 AM

Okayy thanks.
Going to Test that tomorrow when the crimping Set arrive.

About the CR Touch If i actually Fried it, would IT be simpler to get a new one or should i get a different product.

Felix✨Chaos✨OP•11/6/23, 8:16 PM

Like what Kind of Sensor was in mind while Design this Board?

miklschmidt•11/6/23, 11:29 PM

I would definitely get a different product, if you're running klipper, using a spring steel flex plate, and you can adapt your toolhead design i'd recommend Beacon

miklschmidt•11/6/23, 11:30 PM

Superpinda primarily.

miklschmidt•11/6/23, 11:31 PM

Superpinda is an inductive probe with built in temperature compensation.

Felix✨Chaos✨OP•11/6/23, 11:37 PM

Okay thanks for the Info.
Gonna Look Into that Sounds really interesting HACKERMANS

i Hope that everything works correctly tomorrow when i Put the jst Things on the cables

Not Sure If comoletly understood IT now but it should be the Same color Order but upside down. (Somehow pE5 and 6 seems to Mixed Up im the pinout of the Board vs the provided CR Touch pinout If i Put IT in there in order, but idk really... A Bit tired of this CR Touch cable chaos) Just going to try it tomorrow If IT Work IT Work If Not ITS broken

Felix✨Chaos✨OP•11/9/23, 12:01 AM

Finally the Tools arrived

Felix✨Chaos✨OP•11/9/23, 12:38 AM

@miklschmidt big thanks to you i crimped the cables (Not AS easy AS expected) and i now get the Power LED.

Going to Test everything Else tomorrow If something IS damage but i atleast now have a Board that Boots normally
