@dc42 I use this driver because it was provided by the extruder manufacturer and the 6 drivers on the 6HC is already reserved for X,Y,Z.

@dc42 Thank you. That would mean to leave the P-UP, and STALL on the driver also not connected. Is that correct?

Here is the driver documentation.https://docs.dyzedesign.com/stepper-driver.html#duet-configuration

I have never used an external stepper driver, so it is my premier with the duet 1XD board and I try to follow documentation in the Duet Docs and the documentation for the extruder that the stepper is for, but I am little bit confused.

Mainly due to different pin markings on the board, driver and even in the documentation of the driver and stepper itself. The markings of the stepper in the duet docs is also different when compared to the driver I have. I believe that my confusion is caused by fact that I don´t know much of electronics, but I hope you can guide me how to plug it correctly.

The duet3d extension board has 8 pins +5V, D0_STEP-; D0_STEP+,D0_DIR-,D0_DIR+, D0_EN-, D0_EN-, +5V, and the driver in the docs has PUL+, PUL-, DIR+, DIR-, ENA+,ENA-

but the physical driver I have has pins: P-UP,STALL; GND;ENA;STEP;DIR

and when I compare it to the dyze design docs, the supposed pins of the board and even the drivers pins are again entirely different.

Can you please tell me what pins on the 1XD board do I connect to which pins on the driver?

I have some additional questions:

1. What is the difference between single ended connection and differential connection shown in the duet docs for the 1xd board?

2. The steppers required current is 2.7A RMS, but the max output from the 1XD is 2A. Can I plug the PWR connectors of the driver to the same 48V PSU as the 1XD extension board and the 6HC mainboard I use?

We are working on a project to build a large-scale 3D printer with a 1m³ build volume. We want to wire it and commission it ourselves to allow for future modifications, however the complexity of the project has raised concerns about our ability to execute it successfully. So I need your help to answer some questions

For context, my only prior experience includes converting a desktop 3D printer to use a Duet board. And I don't know much about electronics

1. Stepper Drivers and Mainboard Choice:

• Our original plan was to use the Duet 3 6HC mainboard powered by a 48V PSU. We selected six stepper motors (one each for X, Y, and Z axes, plus three more for other functions), each rated for 48V and 3.18A.
• Since the total current output from the board would be approximately 30A, would the 6HC be suitable for this setup, or would we need to consider the Duet 3 6XD instead?
  Heater Control with SSRs:

2. Can the 3.3V IO outputs on the 6HC board control solid-state relays (SSRs) for 230V heaters, or would we need to step up the control voltage to a higher level to ensure reliable operation?

I am still new to electronics so I dont know what could be the issue so I will leave as much information as possible.

I am trying to run heater autotuning with M303 H1 P1 S240. It runs for 60 seconds and then gives error: Auto tune cancelled because temperature is not increasing. During the minute it increases from 28.3 to 28.8°C. I supply the board with 24 V and the current in standby mode is 0.13 A and when the heating starts it is 0.26 A.

I dont know if the values in M307 are correct. The manufacturer of the pellet extruder I am trying to use suggests initial tuning values M307 H1 A940 C810 D22 S1.0 B0, but those are for old firmware version.

Here is my config.g

As stated above. I don't see any controls of the heaters in the web interface. I can't see in tools or extras.

What I "see" in the web control

A few months ago, I successfully converted my Creality K1 printer to use a Duet board, and now I’m working on a more complex printer project with pellet extruder (https://docs.dyzedesign.com/pulsar.html#what-s-in-the-box). Since I’m not very proficient in electronics, I decided to start by connecting and configuring the PT100 sensors for the pellet extruder. I have followed the configuration guide of the pellet extruder but I’ve encountered several unexpected issues that I need help with.

First issue is inside the web control.
1)I dont see configured sensors where I could read their temperature in tools. I have to switch to extras.
2) I cant see all of them in extras either - nozzle is missing.
3) Additionaly PT100 for heater top is showing 2000°C

I came here with 0 knowledge about control systems and you guys made my journey of converting my Creality K1 printer possible. I don't think that I would be able to do it on my own without your help. So as a thank you I just want to share my config files that could maybe be helpful for someone who might find himself in a similar situation like I was few months ago.

I run the factory setup of the printer, only thing I have removed were the load cells on the printer used for homing the machine and I run an IR Z-probe instead.

Config and homing files:
homeall.g config.g homez.g homey.g homex.g

Some prints I am getting with the duet controler.

You can also check how it is pritning here:

I have noticed new way of scanning the bed scanner measuring the eddy current to achieve faster and more precise auto bed leveling. I have found 2 companies making such sensors - Beacon and BigTreeTech. They both state that these scanners are meant for Klipper but I would be interested to use it on Duet. Would that work?

What pins on 6HC can I use to control 3 230 V heater? Or do I need an extension board?

Info about the heaters:

Each heater has its own solid state relay.

Top heater, 500 Watts, 5A for 120VAC and 2.5A for 240VAC systems
Middle heater, 350 Watts, 3.5A for 120VAC and 1.75A for 240VAC systems
Nozzle heater, 250 Watts, 2.5A for 120VAC and 1.25A for 240VAC systems
Many pins can be used as the temperature output control. Your 3D Printer Controller (or motion controller) pins can be as below:

The standard extruder output (E0, E1, E2, etc). These are usually rated at the same voltage as your main power supply (12VDC or 24VDC).
Any available expansion pins. These can be determined by checking the 3D Printer Controller specification pins.

Hi I need to select a z probe for the printer in our company. We are building a 1x1x1m printer using pellet extruder instead of classical fillament extruder. I want to create a mesh of the bed but I am unsure what z probe would be suitable for this application.
I dont think that mechanical probes like BLTouch would have sufficient reach of the probe - required reach would be aroud 2-3 centimeters. Material of the printing surface is yet unknown.
What z probes would be good for this application and compatible with Duet hardware (MB6HC)?

I noticed a header in the docs of calibrating the printer which points to the optimal slicer settings. Why is there nothing to see? I would be interested in seeing the setting for PrusaSlicer

@jay_s_uk Awesome. Thank you very much for quick and great help. You can mark this topic as solved.

@jay_s_uk It finally stopped, but I wasnt paying attention. What exactly does the tuning do? I checked the config.g file thinking that it would modify the heaters parameters, but nothing has changed.

@jay_s_uk How long should the tuning last? Mine is running for over an hour now and for the past 30 minutes have been looping. It goes to 61.3 degrees C, then cools down to 55 and then again.

@jay_s_uk Omg, you are right. Now it works but I still get this error. How can I fix it?

Can you please help me debug what might be the issue when my heating bed is not heating? When I send the M140 S55 command it activates the bed heater but the current temperature does not change and then it gives an error (as in the image). I cannot acces the bed thermistor, but I believe that it works well, because it shows the same room temperature as my chamber thermistor.

I have a CoreXY printer that I'm configuring with a Duet board. While my homey.g file works as expected, my homex.g file is not behaving correctly, even though I've used the same approach for both. I don't understand why this is happening.

I cannot connect it to a company router, so I plugged it into the wall plug next to the one my desktop computer is connected to. Then I checked what IP the computer had, and using a fixed IP with M552, I set up that IP, changing the last few digits, but it did not work.

I asked for a laptop to connect it directly to the computer. Would that work? If so, what steps must I follow to connect it successfully?

I have www, config, and sys folders on the SD card.

I followed every step described here https://docs.duet3d.com/en/How_to_guides/Getting_connected/Getting_connected_to_your_Duet, but I still cannot access the web interface. I have succesfully installed the drivers and so on.. Yet, It still does not work.
