On the Duet 2 expansion slot lets say for Pin 5) E2_STEP and Pin 6) E2_DIR,
Is there a way to switch them with each other?- To tell the control board to switch them.
I understand this is a very strange ask, and the correct answer is to just fix my wiring, but this would save me some time if I can just change a config setting of some kind.
Asking so we can fix prototypes faster, as we make a lot of new devices.

Probed a bunch of random places on the board where the 3.3v and 5v lines are at. They were all the same and were all about 5.5v and 3.5v
The thing is the board overheats the same, even when its only being powered over USB...... must be a damaged MCU.

@Phaedrux
Yes, I believe the temperature reading is correct. Chip and heatsink are too hot to touch, will burn finger.
With everything disconnected, just only VIN12v, it does as I described. Same for USB only.
~1-2 years ago from the official Duet Sales. I believe it was one of the early production boards.
When the board is powered it goes to ~100C on the MCU. Interface works correctly.
Happens both over 12v power and USB power. The ramp to 100C is not instant and takes 1-2min. Tried unplugging everything except for Ethernet cable and input power, still overheats. Added heatsink, did not do much.

M84 idles the motors. Is there a command to tell them to engage other than a move command?
I realize you could do something like this "g1 e0.0001 f10000" was just wondering if there is a magical command to tell the motor "on"
https://docs.duet3d.com/User_manual/Reference/Gcodes#m84-stop-idle-hold
Is there a way to force an ending script/macro/gocde file to run at the end of every print?
I am fully aware of ending scripts in slicers and the Duet board macros. What I am looking for is when a print file is completed, the duet board runs a macro command or another gcode file by name. Even running the something like the pause.g or stop.g file would work this as well.
The gcode print file that just finished does not have any run commands/scripts in the gcode file. And the Duet board automatically runs file X once a print has been completed, no mater what the print is or what is in the gocde file.
@dc42 Up and running. Thank you for the information, it helped a lot. Video of it working: https://www.youtube.com/watch?v=WS5VHpAl5Vc
I do have one more question though.
I have observed very odd measurements from the amplifying circuit output VPP when the Duet board is sending low frequencies and/or with T being low. The duet board VPP output seems constant no matter the speed/freq.
Is this from a poor quality amplifier circuit? Or does the Duet 2 board drop in available current on the PWM line when at lower frequencies? I do not believe it to be the latter, as the Duet board VPP is constant.
I assume this is due to a poor quality amplifier that requires X amount of current coming in from the PWM line from the Duet board. When the Pulse cycle length (T) is short and/or when the Frequency is small, the end result coming out of the Amplifier is small, even going to 0 VPP. When the VPP output from the amplifier is not 0, the IN/OUT PWM frequencies matches, so at least the amplifier does not distort that.
@dc42 Thank you very must for the informative information. We will be try and use an amplifier circuit.
We would use the breakout board, but we have so much stock wire cabling and harnesses that we can not switch to a different type of connector.
I apologize for not using standard/correct industry terminology.
The STEP signal being generated by the Duet 2 board from the expansion slot is VERY short on the "active" time. From my understanding, PWM generation devices should have a uniform even wave length, of equal times of the peaks. Just by looking at the frequency wave, the frequency high peaks are barely able to be registered, and the low peaks are the majority of the output. I am trying to make them have equal high/low peaks.
Here is a video better describing what I am trying to have the Duet board output. A uniform symmetrical wave length, at any speed. Increasing the extruder speed (STEP signal PWM output) just makes more peaks. The low peak time is not equal to the high peak time, which is what I am trying to get.
https://www.youtube.com/watch?v=UC3ZVla6fr0
I have experimented with M569 P7 S1 R0 T4 in the config changing it to M569 P7 S1 R0 T40 but have not had success, as this will distort the wave form at higher output rates. Shown in pictures below.
I would also like to have a bigger Vpp (Peak-to-peak voltage) as the duet only output is ~4.5v Is there a way to increase this?
I am connecting to these pins on the control board.
Pin 2) GND
Pin 25) E6_STEP
Firmware version: 3.1.1
config.g
@dc42 We are connecting it via the expansion slot pins. M569 P9 S1 R0 T4. The E6 pin: Pin 25 and Pin 2
There may have been a word/grammar miscommunication. When I said PWM above, I was referring to the STEP signal.
We are not using any fan or heater connectors on the board currently.
Perhaps it is the amplitude of the pulses that needs to be greater? Is there a way to do this? I may be wildly not correct for doing this, but the voltage output using a multi-meter always measures 0.6v from Pin 25 to 2 when an extruder move command is sent. ~0v during idle. On the cheap pulse generator device, the output is always 6.5v when in use. (I do not have an oscilloscope).
Working on a new project to have the Duet 2 board control very large motors. I have little to no experience with VFDs (variable frequency drives). I am trying to have the PWM signal from the expansion pins run the drive, but I am unable to understand/figure out why it does not work. I think it has something to do with the frequency, frequency type, or voltage, but can not figure it out.
Perhaps it has to do with M569 in the duet config?
M569 P9 S1 R0 T4
Duet config is attached. config.g
I was able to have the VFD be controlled by a cheap PWM signal generator, but not from the Duet board, as shown in this video: https://youtu.be/IXPVMlhlvyg

Hello, we are looking for a recommendation for a newer Duet control board. We currently use the Duet 2, but would like to do some future proofing and make sure we get the right board for us so we can continue using the Duet family of boards. We basically want the same functionality, but on a newer designed board. We are just having some issues finding out the potential combination of boards with expansion boards and what is best for us.
Here are our requirements (what we currently use on the Duet 2)
The Expansion Slot- We use 4 or 5 motors on most of our machines, which use STEP/PWM/PUL signals with a DIR and EN signal. (Direction and enable). The Duet 2 allows for 5 motors of this type. I see that boards like the Duet 3 Mini only have 2 outputs of this type, but is there an expansion board you can use with the Duet 3 Mini to get more outputs of this type?
Stepper Motor Drivers- We also have machines that use 4 basic stepper motors. The Duet 2, having both the expansion slot AND 5 stepper driver slots is perfect for our use case, allowing us to have some printers with hybrid motors, and others with basic steppers, using the same control board! (Just a different config file).
3 or 4 Limit switches. (Endstops)
Ease of use editing the config file.
Networking Ethernet/Wifi capabilities.
Heater is not used.
Thank you for anyone's help who can recommend a board for us.
I am currently trying to set up a heater, but the mass of the object that is being heated is so large it faults. Is there something I am missing or a workaround for pid tuning or using bang bang where it could take up to 10 minutes to heat to 70/C?
Here it is in action!

Here is our teaser video for the Scara Road Runner. It will mainly be used for 3D printing cement with a 1in nozzle from a continuous flow system.
It is using a Duet 2 WiFi, all motors are being run off the expansion pin slot.
We will be printing with material soon, just a few more things to work out. The print area shape will be an elliptical oval that has straight edges on top and bottom of the oval from a top down view. It can do continuous 360 degree rotation.
Hello not exactly a Duet question, but how can I save Predefined Commands in YAT? Every time we set them up it does not save. If you close the current terminal and make a new one it wipes them out.
Thanks.
