Wiring Guide
Wiring the V-Minion 1.0 can relieve stress and improve sleep quality. Follow this guide carefully, and take your time to accomplish each step successfully. The default V-Minion configuration comes supplied with either an SKRat 1.0, SKR2, or Octopus 1.1 mainboards from BIGTREETECH. Rat Rig provide detailed wiring diagrams for these configurations.
01. electronics enclosure
All of the V-Minion electronics fit into the specially designed case. It has been designed to house the power supply, a Raspberry Pi, as well as your printer mainboard, all whilst providing cooling via a built-in 40mm fan.
Identifying Motor phases
If your motors were acquired at Rat Rig, you don’t need to worry about motor pinout, simply follow our wiring diagrams.If you sourced your motors elsewhere, you need to identify their pinout to avoid damage to the board.You can identify the motor pinout using either a LED diode or a piece of wire. Short two pins like on the example below and then rotate the shaft by hand. When shorting a phase the LED will light up or - if you’re using the wire method - rotating the shaft will become much harder.
A very detailed article on the matter is provided in Duet 3D's documentation.
BIGTREETECH SKRat 1.0 Wiring Diagram
The BIGTREETECH SKRat 1.0 is the preferred configuration for the V-Minion as it is fully supported by RatOS. Rat Rig provides a detailed wiring diagram for this configuration.
The BIGTREETECH SKRat 1.0 supports proper PWM outputs for powerfull cooling!
⚠️WARNING! RAT RIG 4028 FANS ARE 12V
Fully read the instructions linked above. Plugging a 12v fan into a 24v printer will destroy your fan.
