Duet muti printer server anyone?

Danal

A "Working Draft" is now ready for review. To load it:

Click this URL: http://danalspub.com/MultiDWMC/
After it loads, use the "Add Printer" button to enter the IP address (and password, if applicable) of at least one Duet that can be reached by regular Duet Web. You can add as many as you wish. You can delete the example, if you wish. Entries will be preserved across reloads.
Wait a few moments (about 10 seconds each for first connect, and first status update).

Comments welcome. Post right here in this thread.

P.S. This will eventually be able to be loaded from a Duet. For right now, loadable only from the internet.

If you re-visit after a few hours or days, be sure and refresh cache.

Example: In Chrome, do a Ctrl+Shift-r

Can it be changed to use hostnames instead of IP?

Assuming that "normal" DWC would work with the same host-name, sure. I'll take the check for IP out.

Edit: Done. Be sure and Ctrl-Shift-r to see the change.

It works!

Hey, it looks great! Im having an issue connecting, I added the IP for one and waited but it fails. I dont have a password on this board so I left the password blank. Could that be the issue? I have Deleted and retried a few times just to be sure. Thanks for the help.

Blank password, meaning "just click done, or just hit enter" is fine. I use that. I've tested it (a little) with a password as well.

Things to check:

Does DWC connect from that same browser/computer, etc. using the same IP (or name)

And, for curiosity: What OS and Browser? And what firmware on your Duet?

Thanks,

Danal

1.18 duet firmware
Chrome browser
Also DWC opens in the browser

I just clicked done with the blank password field.

Very interesting. Close to what I'm using. Hmmm… I may have to put a debugging console log in temporarily... but... I've just changed the central dispatcher/connector to make it more reliable, so, if you don't mind, try again.

You should see "V1.02" in the block of notes, if things have successfully refreshed. (Ctrl+Shift+R).

V1.02 Now available.

Release Notes, 1.02:

Speedup initial connect on page load.
Cleanup wording around IP or HostName in several places
Added "Disconnect and Close" button.
Made individual line "Disconnect" buttons active.
Added completion percentage to status while printing

Release Notes, 1.01:

Allow hostnames (in addition to IP addresses)
Fixed table sometimes not (re-)built properly after add or delete

Nice!

Everything in the above picture is real, updated from connections to real duets, and will perform the labeled actions when clicked, EXCEPT for the gray (white) buttons.

One little bug: under Chrome the printer names are displayed, but under Firefox it continues to show "TBD at first status update".

Will do, I'll let you know how it works

Interesting. Some subtle Javascript difference, no doubt.

Thanks, I will check it out on FF.

In the spirit of transparency: I'd broken this updating of the name from the board in all browsers.

V1.03 now available.

Release Notes, 1.03:
Fixed a bug that sometimes prevented newly added printers from obtaining and displaying the board name (i.e. the name stayed "TBD" forever).

Try 1.03 and let me know. If it still fails to connect, please do this:

Press F12. This opens a split screen. Click on the "console" tab in the split.
Reload the page. Ctrl-Shift-R, just to be sure.
Wait approximately three minutes. Several messages will appear in the console. Please copy/paste and email these messages to me. Don't wait too long!

I am "danal (dot) estes (at) gmail (dot) com".

Thanks!

I'll try right when I get home, it will be 3 hours. I tried late last night with 1.02 to no avail.

Nice server. Currently I am using a split screen with two tabs. I will try this in my 7" screen with raspberry pi 3.
