Warning: Do not turn on SMPS Power supply till Step 10: Powering Up
Note: If you don’t have PCB Heatbed, you can ignore the PCB Head bed connections. Also in RAMPS you don’t need to give power input to 11A terminal, only to input 5A terminal is needed.
WoodMAXi3 Electronics Assembly and Wiring
In this guide, we will assemble electronics and wire them up as per below diagram
Prepare the electronics
Set the stepping mode
Short the PINS (Highlighted in Green) under Step Stick using Jumpers
Theses jumper determines the stepping mode of the step stick. Default is 1⁄16 micro stepping all 3 jumpers need to be installed under drivers for 1⁄16 micro stepping mode
Install heat sink on Step Stick
Install RAMPS1.4 shield on top of Mega
Assembling RAMPS means simply stacking RAMPS1.4 shield on top of Mega 2560.
Install StepStick on top of RAMPS1.4
Note: Make sure to Match the PIN in Step Stick and RAMPS, else the step stick will be damaged
After Step Stick Assembly, note the direction of Trim Pots,
Make sure your assembled electronics looks like the picture
Wire the power supply
Tie up controller board to the Prusa i3 Frame
Connecting Hot ends, Heat bed and Fan
Connector Pairs D8, D9, D10 are used for connecting these devices.
This configuration is based on Firmware configuration (Marlin). Depending on your Marlin firmware configuration you can wire the hardware
- Configuration 1: Hotend (D10) + Fan (D9) + Heat Bed (D8)
- Configuration 2: Hotend (D10) + Hotend (D9) + Heat Bed (D8)
Configuration 1: Hotend (D10) + Fan (D9) + Heat Bed (D8)
Configuration 2: Hotend (D10) + Hotend (D9) + Heat Bed (D8)
You need to reconfigure the firmware and upload it.
In the Picture T0, T1, T2 are for thermistor: Hotend 1 (T0), Heat bed (T1), Hotend (T2)
Connecting End Stops
After following all above steps, your wiring should look like below diagrams
