Cube3 running with e3DV6 hotend!

Holy cow that's purdy!

You know we want to see and hear more of that hack right?

HolyLooking insane!!!

Not much of a hack really,
The extender, I bought exactly this one, 40 pin, 0.5mm pitch.

BTT TFT 24 board, the screen needs to be carefully separated from the board. Don't follow my mistakes, I accidentally managed to cut the LCD ribbon. Luckily I had MKS board with the same 40 pin connector LCD, but with different driver IC, so I had to recompile the software.

Also, I decided to re-use the original Cube screen pcb, it holds the screen very well, plus it has a button
I did a small cut for LCD ribbon, as you can see on pictures.

Now, my next challenges:

Need to design the "cable holder" for this:

And new idea, to re-use this small pcb:
142970536_966975280501898_3896320254805643219_n.jpg

All thermistor, fan, led, IR sensor cables can be connected to the board.
If anybody has a good pinout for it, please share.

Oh, the re-using the LCD is the key to my missing link, thanks! Indeed perfectly good reuse fodder. I wonder if there are extension cable without the PCB.

That black plate the wire holder is stuck in can have the captured loops like they do with the little fan wires. Just strain relieved but easy to dislodge.

Found a good place for the board:
Needs a small printed frame to hold it in place. Will design it soon.
After that I can start proper wiring and assembly.

Guys, whoever traced the pins of this small PCB, please share:

Everything is kindly printed for me by a friend of mine on Prusa i3 mk3, PETG.

Time to start the final wiring.

Badassery!

Nice... My cube3corexy build ist sadly on hold for the Moment...

Guys, If someone has a working original Cube 3, I need your help.

I'm reversing this PCB board:
145877912_544717886485125_3255894053044844412_n.jpg
My Cube is disassembled a long time ago, I unfortunately do not have the exact pinout of J3 15-pin connector. I need your help here.
In order to properly reverse the board, I need to know, where all the fans, leds, sensors and microswitches are connected.
The goal is to find the pinout of J1 and J2. Especially the pins, controlling the keys for led, both 5v and 12v fans, thermistors and so on.
Heater wires will be connected directly to MKS board, without any connectors in-between.
That will result in a much cleaner setup with maximum original parts re-use.

The holder for the board:

Overall progress so far:

Hey kiza, This is the page I remember seeing this on. I have been racking my brain as to where I had seen someone post something about this

Yep, I remember this one, but information is incomplete there.
