Duet muti printer server anyone?

Danal

@Austin55:

I am much more interested to know more about duet printer server. I will wait for next updates.

About

A Duet Board/Firmware?
"Duet Web Control" that comes with the board firmware?
"Multi Duet Web Monitoring and Control" which is being discussed in this thread?

There is no (known) way to discover a Duet. (Otherwise, I'd be using it…).

Actually there is a way to discover a Duet WiFi if you have an Android smartphone or tablet. Look for "Find my Duet" on Google Play.

Ah, interesting… is the underlying technique usable from a browser/javascript?

And/or is the "Find my Duet" source available?

@Danal:

The Duet server should be treated as insecure, with or without any given header, etc. For one thing, it doesn't do HTTPS, and so the password should be considered open to discovery by anyone on the same network. Traffic to and from a Duet should never be exposed outside the network segment it is on… NEVER to the public internet. It should ALWAYS be proxied with external authentication and external facing HTTPS provided by that proxy.

I agree. I just think it's a shame that this is the case. TLS might be a bit too much to ask, I guess, but some rudimentary cookie-based authentication sounds reasonable to me. Attackers could still sniff the traffic and find the password when the user authenticates, but it's much better than nothing.

@Danal:

With regard to "Any Arbitrary Website", the code loaded from a malicious website into a browser that was already connected to a Duet (via DWC or MultiDWMC) would have to find the Duet's address. There is no (known) way to discover a Duet. (Otherwise, I'd be using it…).

Yep, apart from using a zeroconf address (that you would still have to guess). However, a web page could iterate through common local IP numbers (say 192.168.0.*) and the chance of finding it would be relatively significant. I don't like the idea of security through obscurity.

So mDNS / Bonjour is supported by Duet firmware. Unfortunately, there is no way (I can find) to browse for a mDNS / Bonjour directly from Browser based Javascript.

This does (somewhat) address the security concern.

By the way, I'm taking a short pause to re-package "Multi" for github, and create build scripts that produce a .zip package suitable for "serving from Duet" and a package suitable for "Serving from anywhere".

More soon… meanwhile, keep the feedback and design ideas coming...

for now, if you want to take a look.

BuildA3DPrinter.eu

I really like (and want!) this. We are building a farm of at least 10 large scale custom printers (build volume 1000x1000x1200mm at least).
This would be a great addition to keep everything in check.

My wishlist now would be:

Make printers manually sortable to organize them in a particular order.
Show name of the current print.
Make the action buttons customizable. I do not want a calibration button but for instance would like to have a babystep button or something else. Making it possible to select the buttons I want would be awesome.
Make the theme match the Dark theme. Luxury wishlist naturally.

I can help with the Dutch translation if you want. Native Dutch speaker here…

Keep up the great work!

Danal

Sorting: On the way.

Name of current print: On the way.

Action buttons custom: Probably not. Lot of work, and the real answer is just to click in the name/ip box for that printer and open full DWC in another tab.

Theme: Maybe. Probably, but no absolute commitment. Under the covers, this uses the same CSS as DWC, so this should be relatively easy.

Dutch translation: Under the covers it uses the same language files and translation scheme as DWC, at this moment, the language is greyed out, but I do plan to turn it on. When it becomes active, there will need to be a few more entries in each language…. for you to do the Dutch ones should be erg makkelijk.

R2.00 posted to http://danalspub.com/MultiDWMC/

Changes in this release:

Repackaged to make building for Duet vs. "any server" easier.
Added sorting of rows. Not entirely happy with how it works internally, may change it.
Added file name and size when printing.

Should be fairly usable at this point. The package builders for "Server from Duet" and "Serve from anywhere" are working and lightly tested. I will put this on github in the next few days.

Danal

R2.01 now available.

Including "Serve from Duet". See: https://github.com/DanalEstes/MultiDuetWebMonitor

Or:

Download the github file (via the download button, NOT via "right click")
https://github.com/DanalEstes/MultiDuetWebMonitor/blob/master/MultiDuetWebControl-Duet-2.01.zip
Upload to Duet via the normal upload process. Do not unzip.
Invoke via HTTP://your-duet-ip-or-name/multi.htm

Feedback welcome.

Jeeebus H Mary and Josef !!!! Where has this been all my Duet life ? Thanks for this - finding where this machine is on my net has been doing my dome in for weeks …

P.S. - very cool project / server app buddy KUDOS.

Thanks are due to chrishamm for writing it, not to me.

Works great, monitoring 3 machines. Extremely easy to install and setup.

Excellent work. I could see this being very popular.

Was there any progress on this? Is it possible to contribute in some way?

cool this should be promoted a bit more

It is "up and running", available now:

Suggestions or feedback welcome. Post in this thread. Also, for contribution... what are your thoughts? What would you like to see? Of course, it is Github, so you can just fork it.

Thank you. After it is used for a couple of months, I'm going to ask Chris and/or Dave to either include it, or at least link to it from somewhere more obvious.

Just my 2 cents but as a 3d printing shop i'd be willing to pay to get something like this developed... I'm sure there is some other out there who would be ready to contribute financially. I can't say for sure that you have a business case here, but i'm pretty sure that being able to develop an almost turn-key print farm system using duet boards would be of interest to many people.

When you look at other solutions available it's really not so seducing. Stuff like 3dprinteros.com who offer farm management where you have to buy their box (which is a pi3) to hook up to some average board... I mean, the duet perform better than most other boards out there and it's already networked.

I was talking to my programmer about building me something similar to what you are doing as a webpage layer in between the duets and the user to watch all my printers. I can't really help on the coding side of things because it's not what i do best. I'm more of a project/UI guy. We should have a talk together about all of this... I mean if you wanna push it as a free hobby thing i respect that but just doing a bit more would probably turn out to be a business solution for print farm management.

I think it may be worth your while talking to Chrishamm, because some of our OEMs have similar requirements and he may be working on something similar already.
