Voron V2 - SKR 1.4 Wiring

Initial Preparation

  • If using the TMC2209 stepper drivers, use a small pair of wire cutters and remove the pin marked in purple. This is to disable sensorless homing which is not needed for the V2.

  • Reconfigure the on-board jumpers as shown.

MCU X/Y/E, Hot End

  • Place stepper drivers for X, Y, and E in positions X, Y, and E0
  • Plug in stepper motors for X, Y, and E in positions X, Y, and E0
  • Plug Hot End thermistor to thermistor TH0 (P0.24)
  • Plug Hot End heater in to HE0 (P2.7)
  • Plug Hot End Fan in to HE1 (P2.4)
  • Plug Part Cooling Fan in to Fan (P2.3)
  • Connect X end stop to +X connector (P1.28)
  • Connect Y end stop to +Y connector (P1.26)
  • Wire 24V and 0V from DC power supply to Power In
  • Connect USB Cable to your SKR 1.4, but do not connect it yet to your Raspberry Pi

MCU Z, Bed, Exhaust Fan

  • Place stepper drivers for Z0, Z1, Z2, and Z3 into positions X, Y, Z, and E0
  • Plug in stepper motors for Z0, Z1, Z2, and Z3 into positions X, Y, Z, and E0
  • Plug Bed Heater thermistor in to TB (P0.23)
  • Plug in Exhaust Fan in to HE0 (P2.7)
  • Plug in Controller Fan in to HE1 (P2.4)
  • Plug SSR Control for Heated Bed in to Fan (P2.3)
  • Plug Z Endstop Switch into -Z (P1.25)
  • Plug Probe PWR and GND into FAN2
  • Plug Probe Signal (with BAT85 diode) in to Probe (P0.10)
  • Plug display wires in to EXP1 and EXP2
  • Wire 24V and 0V from DC power supply to Power In
  • Connect USB Cable to your SKR 1.4, but do not connect it yet to your Raspberry Pi
