Duet 2 vs Duet 3

While a Duet 3 won’t be replacing the Duet 2 anytime soon, it’s a much more professional electronics board that adds a range of options and functionality to your machine build. Although the Duet 3 may be overkill for most users, these options are not for everyone you do get much more out of Duet by using a Raspberry Pi .

Duet 3 Raspberry Pi

• Mount networking to access shared files
• Offload the duet so it can focus on executing the gcode’s which means potentially faster 3d printing
• Directly update or upgrade Duet firmware without searching through Github
• Larger variety of touch screen options rather than PanelDue
• More options with the new Duet Software Framework (DSF)
• 3rd party developers with the single board connection separate from the main board

Duet 2	Duet 3
5 Stepper Motors	6 Stepper Motors
2.4 AMP Peak	6.3 AMPS Peak
Better documentation	More Expandability
TMC2660 stepper drivers	Trinamic 5160 stepper drivers
	CAN Bus
	Raspberry Pi
	Plugins
	10 PWM outputs
	Tool Boards
Duet 2 + Expansion Board	Duet 3 + Expansion Board
12 Stepper Motors	24+ Stepper Motors

Duet 3 YAT Commands

• M115 Checks Firmware
• M552 Checks Ethernet
• M552 S0 Stops Ethernet
• M552 S1 Starts Ethernet (displays current IP address)
• M552 S1 P0.0.0.0 Sets Dynamic IP (P=desired ip address)
• M552 S1 Pxxxxxx Sets Static IP

Reverse Motor Direction

M569 command is for the motors in the config.g file. 

Reprap Gcode M569:_Set_axis_direction_and_enable_values

• M569 P0 is for the X driver,
• M569 P1 is for the Y driver 
• Change S1 in that line to S0 or vice verse to reverse the motor direction.

To Invert Motors: On Config.g file

M569 P0 S0 ; Drive 0 goes forwards
M569 P1 S0 ; Drive 1 goes forwards

M569 P2 S0 ; Drive 2 goes forwards
M569 P3 S1 ; Drive 3 goes forwards
M569 P4 S1 ; Drive 4 goes forwards

Motor Drives are mapped as:

0 = X

1 = Y

2 = Z

3 = E0

4 = E1 etc

“S” Parameter changes motor direction:

EX.

Change

M569 P3 S1 

To

M569 P3 S0

Make sure your homex.g / homey.g / homez.g fileshome in the right direction:

Ex. X-Endstop positioned on right side.
