please publish schematics for the board with the USB-C connector in the hotend

Hi

I like to design a swappable hotend and need the schematic for the USB-C board on the hotend. Would be nice, if I don't have to reverse engineer... :+1:

Thx, Markus

Yes if you could release that would be great, I just want to make it smaller.

@FotoFieber, @BlueM92 did you get any schmematic? Or done some reverse engineering?

Thx, Jan

Use at your own risk and check it twice... :) 24V: A1, B1, A12, B12 (which is usually GND on USBC) GND: A4, B4, A9, B9 (which is usually V+ on USBC) TH+: A3, B3, A10, B10 Neopixel Data: A8, B8 CNC Fan-: A6, A7, B6, B7 Heater-: A2, B2, A11, B11 X Min: A5, B5

There is a step down converter for the neopixel on the hotend pcb.

@FotoFieber Thank you, is the usb-c cable custom or a stock one?

The 'C' cable uses USB style connectors but is not a USB cable, definitely custom.
