12v fans again.

That's because the buck converter output doesn't need to go anywhere, the ground is tied in the buck converter between input and output.

I've another thread about fans in the hardware wishlist section, it seems duet3d's presumption is we would buy correct/same voltage fans not adapt various fans at different voltages. But that's what we want to do. If there was a clever way of having multi voltage fans then it would be worth considering.

I'd happily liase with Tony about making a better version of these diagrams and putting them on the wiki.

@DjDemonD:

It is an expensive board but then if this type of thing is not very comprehensible it might be wise to do a bit more research before undertaking a build. A basic grasp of how it works and what is a good idea and bad idea is a requirement when building a 3D printer. Get a clone ramps/mega and build it first, if you fry that its only £20. If it works transplant the duet in, there is not much that isn't a straight swap.

I think your diagrams are good but I have to kind of disagree with what you are saying here. First, this issue is pretty specific to the Duet. Second, I have built 2 repraps and an MPCNC as well as lots of other projects like a laser for the mpcnc, a custom grow light with mixed high wattage COBs…etc. I am the guy in my circle people come to for this kind of thing but the cost of this board along with the relatively small userbase and therefore smaller amount of information available is plenty of cause for hesitation when going beyond the basics IMO. I think the forum is excellent and DC42 is amazing. The wiki is extensive but the vocabulary is a bit too technical sometimes and more graphical examples would go a long way. Also, there is very little available on Youtube. Probably a good opportunity for an aspiring Youtuber.

.

Finally. The information I wanted to have. If an output doesn't need to go anywhere, then have it annotated on a diagram, a note exactly like the one above, but do not leave any blanks. Avoid ambiguity, especially where electricity is concerned. No broken hardware, no additional cost and inconvenience. Everyone is happy.

Fans are different. They are the most important bits of kit for safety reasons. Given the choice of voltages, numbers of wires etc a better support for fans in hardware and/or documentation is important. It becomes a selling point as well.

I'd put ELCBs and even fuses above them.. And AFIK no fan failure on a 3d printer should result in anything worse than a over temperature event and a failed fan. Possibly a load of ground filament and a hideous blockage if it's the cold end fan.

I agree that perhaps some of the documentation should be a little more accessible. But being an expensive high end board it isn't really marketed at the less experienced, and I would guess fewer people who are less experienced buy one.

I don't see why being high-end should make it less accessible. It's not like the RAMPS board is really a simple solution. It's just cheap. I would think a more expensive product should be easier to use. Just to be clear really like the Duet so I don't mean to bash it or the makers it's just that DC42 wouldn't have to put so much time into the forum if things were handled a little differently.

Duet targets the DIY crowd. That means everyone who chooses to buy it. Being an expensive, high end board it should have better documentation. DC42 does a great job fixing bugs and developing new features. What is lagging behind is user manual. There have been several comments made on this forum about the WIKI side of things but nothing that I can see has been done to address them. Is it just too hard?

dc42

The documentation is being migrated to a better platform, which will make it easier to improve.

Thanks DC42

Sweet!

@djdemond I know this an old post, but its the one I need, and in particular the diagrams you posted before the forum was moved over to the new format, which it clearly did not take the posted pictures with it. Is there any chance you could repost them, please?

@dunstonuk - thats annoying if postimage links have not migrated

@djdemond I've noticed that too when searching the forum reading older threads where they are obviously referencing some images, but there is nothing there. Very confusing.

@djdemond said in 12v fans again.:
Thank you so very much
