Voron V2 / Trident - MKS/Makerbase Monster8 Wiring

Initial Preparation

Set jumpers as shown:

MKS Monster8 preparation

Green – Add Jumper
Red – Remove Jumper

  1. Insert only the jumper in the Green and remove all other jumpers in the Red in order to use TMC2209 UART mode.
  2. Remove all the jumpers of DIAG to avoid the influence of TMC2209 DIAG on the endstop.
  3. Set the USB-PWR jumper to off to avoid the interaction between the USB 5V of raspberry pi and the DC-DC 5V of the motherboard.
  4. Set the six jumpers to VIN to set the fan voltage to the system supply voltage.
  5. Set the jumper to VIN to set the probe voltage to the system supply voltage.
  6. Set the two jumpers into I2C to enable the I2C output pins.
  7. Set the jumper to 5V to set the driver power.
