Kirigami PCB Mod

Overview of the PCB's

This mod adds two PCBs (Frame PCB, Kirigami PCB) and a cable (Cable) to the V0.1/V0.2 that can aid in wire management and routing.

There are also optional things like a Bed Fan or a Kirigami-Front.

Frame PCB

The frame PCB mounts on the side in the electronics bay of the printer and combines all cables into a single 10 pin Micro-Fit 3.0 connector. (With neopixel loop-through.)

Kirigami PCB

Mounted on the Kirigami bed mount, this breaks out the 10 pin harness into all needed connectors.

For the RGB lovers among us: Kirigami U.F.O.

If you have a Neopixel in your Kirigami front, please note the following:

Cable and chain

The Cable is a dual ended 10P (2x5) microfit cable. The connectors are wired 1:5, 6:10 so pin 1 connects to pin 5, pin 2 connects to pin 4 and so forth for all 10 pins.

Only 2 of the 10 wires are shown for clarity. Connect each number to its opposite. (in it's row!)

Note: Don't use 20 AWG wire on all ten!(!!!) It works, but it's a s**t job... Ask me how I know...

Note: You don't need the chain-end spacer if your chain is "V0.1-spec"!

V2+:

  • Link to U.F.O. variant

V2:

  • Moved Screw Terminal postition on Frame PCB and rearranged positons of the connectors + changing heater to Screw Terminal on the Kirigami PCB

V1:
