We are excited to officially announce a new Duet Mainboard:

The Duet 3 Mini 5+ is an evolution of the Duet 2 Maestro, It provides 5 on board drivers and the normal compliment of heaters, fans, IO, LCD etc. There are a Wifi and Ethernet variants with the option of using an SBC for control in the same manner as other Duet 3 mainboard. Expansion is more limited, it does not support the CAN-FD bus (EDIT: it does now) but does have a header for a three driver expansion board (EDIT: now a two driver expansion board).

Ethernet version shown

We will have more news shortly, including RRP and a call for participants to take part in limited initial prototype testing.

We have just started supplying out resellers with the new version of the Duet 3 toolboard: v1.1

Key Changes:

• Added a LIS3DH accelerometer.
• Changed all headers other than VIN, OUT0 and CAN to JST PH right angle connectors. (Thanks @KarlMarklund who did this as mod to an older version)
• Added a footprint for a Omron D2FD-1L30-1T or similar switch (may be useful for tool dock confirmation).
• Added a solder jumper that brings a 120R CANFD bus terminating resistor into the bus circuit to allow a toolboard to be directly connected to a Duet 3 mainboard without a tool distribution board. Thanks to @Nuramori and @bearer for this suggestion
• Board dimensions changed slightly (mounting holes unchanged)
• Added a jumper to switch VOUT on OUT1 and OUT2 between 12V and VIN. Thanks @TLAS for this suggestion.

Documentation has been updated here:

For info, due to an increased number of spammers we have had to introduce the following changes:

1. No profile website, background image, description can be set for new users until they have a reputation of 3 or more.
2. Unverified users (users who have not verified their email address) have limited posting ability - just new topics.
3. Some users will have to have manual approval before they can register.
4. Our T&Cs for using the forum will be updated to make it explicit what is acceptable or unacceptable as far as linking out to external websites from your profile.

I realise that for some users who do not have an email address set, or verified, these new restrictions may be annoying. We are not doing this because we want to harvest your email and start spamming you! Quite the opposite it is to reduce the admin overhead of keeping the forums as spam free as possible.

The email address you register on the forums for is there to allow verification, and then following that for notifications (e.g. someone replied to your post or tagged you). All notifications emails can be configured in your profile and you do not need to receive any of you do not want to.

For information we do use other strategies to reduce forum spam. None are 100% effective, hence the layered approach.

Please also keep flagging spam posts or profiles when you see them in case they are missed by an administrator.

We have been working on a Scanning Z probe for Duet 3 / RepRapfirmware, I am happy to announce the details now:

https://www.duet3d.com/blog/Duet3d-Scanning-Z-Probe

https://docs.duet3d.com/en/Duet3D_hardware/Duet_3_family/Duet_3_Scanning_Z_Probe

We are aiming to get supplies to our resellers by the 22 of November

Over the upcoming Holiday season there will be a few days with no "official" forum support.

25 & 26 Dec
31 Dec, 01 Jan

In addition between 24 Dec and 02 Jan, on the other days, there may be more limited support.

This is to allow for the Duet3D team to take some days off over the holidays. It is not to discourage you from posting, and we will do our best to get back to you when we are back on the forum.

I would like to take the opportunity to wish everyone a happy end to 2022 and best wishes for 2023!

Duet3D has teamed up with Team Gloomy to change the current "Team Gloomy" discord server into one for RepRapFirmware, DWC, DSF and associated projects:

https://discord.gg/uS97Qs7

There are a number of reasons for this, but at its core its to address the misconception that RRF is only for Duet3D hardware. As an opensource project it is broader than Duet3D the company. There has been a lot of discussions recently about opensource within the 3d printing community. I am not going to attempt to address that here and now, however this step underscores the project goes beyond any company or individual.

We have long hosted discussion and support for the Team Gloomy port of RRF on this forum (and the whole community has benefited from @jay_s_uk, @gloomyandy, @Falcounet and others support and contributions).

I had personally resisted a move to Discord for two broad reasons:

1. I think forums are superior for more detailed technical support as the conversation is organised, easier to respond to in long form, search engine indexed and available as a reference for people with a similar issue.
2. Discord is another walled garden, they are not publicly indexed and we could lose the community built there if Discord shuts, or becomes enshittified like other social media platforms.

That said, the community is already there in a large part (both a lot of RRF users, and the wider 3d printing hobbyist community). Also Discord has recently introduced forum like channels with organised posts which go some way to address point #1. Discord bots allow for automation of functionally and could in theory be used to cross post with the forum (if someone know more about this please let me know!) , that in turn goes part way to address point #2.

I do not want Discord to move discussion away from the forum, however it already has to some extent. By working officially with Team Gloomy on discord it avoids further unnecessary splintering of the community. (something that would happen if Duet3D started its own public discord server).

We will keep the forum running for the foreseeable future and continue to provide support there, as well as a place for the community to post if they choose to do so.

We have completed our prototyping phase of the Duet 3 Mainboard and will be starting a limited initial production run shortly.

Headlines:

• 6 Stepper channels, at least 4A per channel.
• High speed dedicated bus to a single board computer.
• 2 CAN-FD buses for expansion.
• 10 PWM outputs for Bed heater, extruders, fans (example configuration is 3 extruders with 2 fans per extruder).
• 9 IO headers for Endstops, probes, filament sensors and other low bandwidth sensors.
• 4 Thermistor/PT1000 inputs and support for 2 temperature daughterboards (4 PT100s or Thermocouples).

Boards from this run are available for pre-order here:
https://www.duet3d.com/Duet3Mainboard6HC
This is on a first come first served basis.
We will begin delivery the first week of September, in the order we receive your purchases.

Initial documentation is available:
Duet 3 Mainboard 6HC Hardware Overview
Duet 3 Mainboard 6HC Wiring Diagram
We are also busy testing the second set of 3 channel expansion board prototypes, there is some more information on these here: Duet 3 Expansion Hardware Overview

Duet3D will be exhibiting at Formnext this year Hall 12.1 , stand G91. We would love to chat to anyone visiting,.

Its going to be a busy show, while there are 6 of us there we have back to back meetings for all 4 days so don't be surprised if there is limited forum interaction with @dc42 @chrishamm and @droftarts for next week.

Talking of @droftarts he has undertaken to post pictures here as the show progresses.

We will be showing off our new scanning Z probe (details to follow before the show starts), the production Motor 23CLs and a new <to be announced>

From 23 Dec 2023 to 02 Jan 2024 there will be reduced forum coverage from @Phaedrux @droftarts @dc42 and @chrishamm. The forum will be checked over this period but not as frequently and not all posts will be able to be answered. We would appreciate your patience while we take an end of year break!

Thanks for everyone for being part of this community over 2023, I would like to wish you all a happy and successful 2024!

Forum rules

These are the Forum Rules you agree to when you sign up:

• Be respectful: everyone is here to learn, help and contribute.
• No personal attacks: discuss an issue rather than attacking the person.
• No spamming: this will get you banned immediately. See the SPAM section below.
• You must verify your email address in order to get access to full posting/reply/uploading images functionality.

Changes/Additions to Rules:

• We reserve the right to expand on or change the rules as we grow.

Breaking the rules

• Generally we will warn you before banning you.
• Repeated offences will lead to banning.
• Breaking SPAM rules will lead to immediate deletion of your profile and SPAM content.

SPAM

Spam is unacceptable on this forum, if you are not sure what you are about to post is SPAM then ask one of the moderators or administrators. Spamming includes SPAM in your user profile and chat messages. Some non exhaustive examples of what we consider SPAM:

• Off-topic posts with links to external websites. We have an "off topic" category and discussing off topic matters there is fine, just don't use that as an excuse to link out to stuff in order to drive traffic there.
• Links in user profiles to commercial websites. The exception to that is Duet resellers and OEMs. Hobby or personal websites are normally ok for active users. If you register, do not engage on the forum and have a link in your profile you will potentially fall foul of the SPAM filters.
• Descriptions in profiles that are spam or SEO related
• Posts or links to products/service websites, that while may be 3d printing/cnc etc related (and so not necessarily off topic) are clearly there to drive traffic to that website and not for discussion. The exceptions to this are Duet3D resellers or OEMs. If in doubt, ask.

Please flag spam posts or profiles when you see them in case they are missed by an administrator.

@Kiolia thanks, appreciated!

@Kiolia please can you confirm this implementation is working for you in 3.6beta2. From the release notes:

https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-3.x-Beta#reprapfirmware-360-beta2:

• heater feedforward based on extrusion rate now works on heaters attached to CAN-connected expansion and tool boards

@Kiolia please would you confirm these issues are fixed for you in 3.6beta2

@T3P3Tony aaaand its back!

As the title says

May be a bit quicker.

I just rewatched Ian's interview with Tom at TCT show from 2019.

I sadly must report that Ian "Deckingman" Pegg has passed away. Ian was a hugely valued member of this community for a long time and he will be missed, especially by his friends at Duet3D.

His work on is amazing stacked CoreXYUVAB colour changing machine, and 6 input mixing hot end stretched what was possible in this space.

@Notepad i have uploaded it here:
https://github.com/Duet3D/FilamentMonitors/tree/master/Roto_Filament_Monitor/enclosure

@p8blr could you wrie some conditional gcode.logic to handle this in the event macro? So only trigger an event if the driver is enabled?

@developeralgo222 we cannot make G an axis letter so maybe openPNP can be modified to accept lower case axis letters?
