BLV mgn Cube

3D Printer

Hi, my name is Ben Levi and This is BLV mgn Cube - an open-source 3D printer project. building your own good and reliable 3D printer is the main purpose of this project. Basically, it's an open front structure CoreXY 3D printer, based on

mgn linear rails for maximum accuracy, efficiency

and high print quality.

At this point, we will install all the necessary wiring.

The wiring process is a critical step and you must perform a double check on each wire you install.

The whole process itself can take around 3 hours and sometimes more, depending on you. If you are lucky and have the  FYSETC kit the whole wiring process will take about an hour. FYSETC kit has a wiring diagram has an optimized wiring diagram, all the needed cables ready to be installed, all the stepper motors wires arranged in the right order, labeled and have plugs. They created a unique PCB for the neopixel rings (5 minutes installation) based on the original neopixek project - plug and play. so it saves a lot of time. so pay attention to the type of wiring diagram you are using.

Few tips

  • Please wire your 3d printer while the AC plug is not connected to any power source.

  • make sure to crimp every cable you are connecting to the PSU (FYSETC kit cables are already pre-crimped).

  • Don't mix negative and positive wires

  • double check every wire.



If your fans rated as 12V and you want to use them

on a 24V - this is the right way to wire them without damaging the board/fans.

IF you are lucky enough to have the Duet 3 board - this is the wiring diagram for you.

FYSETC OPTIMIZED WIRING - for fysetc kit only



Fysetc kit comes with a bl-touch autoleveling sensor, this is the wiring diagram.

5 minutes installation - this is how you wire the neopixle rings. all the cables are ready, neopixles has pins soldered on them and ready to be installed. You can't go wrong with the plugs 2pins and 3 pins, piece of cake!
