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.

@droftarts Thanks for the guidance. Thats unfortunate that no one has done it yet, but once I manage to convert my machine I will share it with you so other people can use the configuration without the hustle.

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 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.
