Chrishamm and I agreed yesterday that it was time to move the version number of RRF on from 1.09. Accordingly, I am pleased to announce release 1.10 of my fork of RepRapFirmware, available at [github.com] (follow the link and press Raw to download it). The changes since my last official release (1.09x-dc42) are:

* Added support for firmware retraction (G10 with no parameters, G11, and M207). This is mainly to better support mixing extruders. To use it, configure "Firmware retraction" in slic3r, then set up your retraction parameters in config.g or in your slicer start gcode using the M207 command, see [reprap.org]. When using a mixing extruder, all extruders associated with the current tool will be retracted by the amount configured, regardless of the current mix ratio. Retraction speed and length are not affected by the M220 or M221 commands.

* Merged in chrishamm's 1.09z networking, webserver, print monitor and iap.bin changes (thanks chrishamm)

* Fixed a bug that sometimes caused auto-IP address allocation via DHCP to fail at startup (thanks chrishamm)

The recommended web interface is DuetWebControl 1.11, available in the SD-Image folder of my repo or direct from chrishamm's repo at [github.com] (download the zip and upload it on the Settings page of the web interface).

If you are already using a recent version of my or chrishamm's 1.09 series firmware, there is no need to change your config.g or homing files.

Got the new version uploaded. Was glad to see that fix for the auto-IP fix as I believe that has been a problem I have been fighting with. I was testing out the network connections and tried connecting via Telnet. I get the prompt for the password, but always get an error, 'Invalid or too long request'. Anyone else seeing this problem?

ElmoC, that was my bad, I expected Telnet and FTP requests to be sent in one chunk rather than char-by-char. I noticed the same problem yesterday morning, but at that time dc42 had already checked in his final version. I guess if you use Pronterface or the stock Telnet client instead of PuTTY, you can work-around this problem until we release new firmware versions.

Dario, that's a watchdog reset and not a "normal" software reset. Could you tell us in detail how this problem can be reproduced?

It is not a stable error condition... was doing "home all".... after a simply reconnect and "home all" again.. is now printing
ah... ok I'll refresh the JS folder asap

Thanks

I'm getting a couple of problems with the web interface; the majority of the time it sort of half loads and sits there forever trying to load. If I reboot the duet it will then sometimes load but when I upload some gcode I'm presented with an AJAX error seen here:

When that happens I get the following blurb over the serial connection:

                                 Network::ConnectionAccepted() - no free ConnectionStates!
          Network::ConnectionAccepted() - no free ConnectionStates!

Repeated many times
and

Network: Connection error, code -11

repeated a few times.

The gcode upload is working as I can print from the SDcard with the PanelDue.

When you say stock Telnet client, which one are your referring to? I just tried the Windows 7 one and got the same error. And the latest version of Pronterface I can find (03 Feb 2015 zip file with Printrun 2014-08-01), doesn't have a Telnet option that I can find.

Thanks dc42 and chrishamm for the RRF and DWC
I see that you two have been merging each others' work/changes in the recent releases
What are the main differences between the 2 branches now?

Dario, I can do you a build with a higher watchdog timeout, to see if that helps. I see that chrishamm increased the watchdog timeout in his recent versions, I'm not sure why he did that - maybe his new networking code needed it. In the mean time, if you have the USB cable connected, try printing without it.

EDIT: I got that wrong - chrishamm and I both use a 1 second watchdog timeout. But chris is aware of this issue you are having, and is doing some more tests on the recent changes to the network code.

Hi David,
I'm getting errors on both last versions and no USB cable connected (used only for firmware update until the new web gui).
Randomly reset....terrible.. back to 1.09x-ch the print is done.....
Fortunately we have a lot of stable versions....

Going back to RepRapFirmware-1.09x-dc42.bin fixed my problem.

There is also 1.09z-rc1 available here [github.com]. This version predates the latest round of network code changes.

I should have mentioned I tried downgrading to that first before 1.09x, but I got the same errors as with 1.10.

Same problem here, unfortunately. Updated to 1.10 and DWC 1.11
It barely loads once after power-up but doesn't connect and doesn't respond any more. Something like ERR_EMPTY_RESPONSE

I have to roll back to 1.09x now... via bossac, I can't even get settings page to load

Hmm, I'm sorry but I have not been able to reproduce this problem on my own setup. Could you do the following:

1) Download and install Wireshark
2) Attach a USB cable to your printer
3) Install dc42's 1.10 or my latest beta firmware on your Duet
4) Open Pronterface or Arduino IDE, and connect to the printer
5) Enable debugging for the network and webserver modules via "M111 P1 S1" and "M111 P2 S1"
6) Start a new Wireshark capture
7) Try to load the web interface
8) Send M122
9) Send me the entire USB log and the Wireshark dump

I hope that will give me a better idea why it's happening.

i am trying to update through dwc to the 1.10 of dc42 from 1.09x but i am gettting a m997 error.

I'll probably do that tomorrow.
I haven't tried your firmware, but 1.09x corrected the problem, and then 1.10-dc42 broke it again.

I also noticed that the web interface works somewhat better in the same network, and worse when forwarded outside. Not sure if it's relevant.

yeap i did . i uploaded the last file of urs and i found it renamed to what you have just told . anyway i ll do it the old fashion way.

Delta Printer
Duet 0.8.5 firmware 1.19

Same problem here.
After upgrading to 1.10 / 1.11 I can connect via webinterface and upload files and start prints etc.
But once the browser was closed a reconnect is no longer possible while in a print.

Edited 3 time(s). Last edit at 03/29/2016 09:52AM by critical_limit.

@chrishamm

From a PC in the same segment with the printer everything works OK. IE11 loads the web-interface really fast, but there's a few seconds delay in Chrome. I closed the browsers and opened them a few times... no problems.

From another PC where the printer IP is forwarded it gets weird. When I open the web-interface in IE11 and it loads, but doesn't connect, and after that it's completely dead.

I'll try Wireshark now...

@chrishamm

Here's the Wireshark log. It ends when I press Stop in IE11, because the page doesn't load any more.
[www.dropbox.com]
I start Wireshark on a PC with 2 interfaces, 192.168.100.1 (sharing the internet from another interface) is connected to WAN port of a router (192.168.100.121), the printer is 192.168.0.121 on the router's LAN, and it's port 80 forwarded to the router (192.168.100.121). I understand that it can be a problem with my network, but 1.09 handles that pretty well...

About the USB log... no response to M122. The board seems to hang completely after that exercise.

@chrishamm

Sorry there was some USB log in Pronterface window.
Probably not complete but it shows some errors
[www.dropbox.com]

Thank you very much, pkm, those logs were quite useful. I have prepared another firmware binary here. Could you try it out and let me know if that improves your situation?

I found a problem in the firmware that could cause the connection closed handler to be called twice (because your PC always sends one RST packet every time while a connection is being closed), but I expect this version to fix the underlying problem. If it doesn't fix that, you'd have to repeat the exercise above.

Great that I could help. I'll try the firmware tomorrow, thanks!

BTW, what is the difference between your version and David's?

The firmware seems to work, thanks a lot!

Now IE11 loads DWC very fast on the troublesome PC too, and there's a delay in Chrome (on any PC). I can use Wireshark with Chrome, if you're willing to look at it.

new firmware works fine also on my mac with Safari.

But can somebody tell me how to edit the config.g via the webinterface?
I can edit, but changes arnt saved. Is it due to Safari or did I missed somthing?

Probably Safari. IE11 doesn't save changes and doesn't suggest to reset. But from Chrome it saves and resets.
