Can´t print with extruder 2.



  • Now it actually happened with T0 as well (for the first time), crashed with five layers remaining at a five-hour spiral vase print.
    I'm going nuts, what can cause these crashes?
    As I´ve said before, it happens every time with T1 but almost never with T0 (this was the first).
    I can´t see anything wrong in the config or g codes (but I´m no expert needs to be said).
    And I don´t think that it´s a wiring issue since the problem follows that extruder that is connected as T1 on the board.
    Anyone else that experience mid-print faults, that might have a solution to my problem?
    Could it be something wrong with my board?

    Please explain what you mean by "crashes". Does the board reset? Run M122 to find out. If the "Last reset time" corresponds to when the print stopped unexpectedly, instead of before you started the print, tell us what it shows for "Last reset reason" and "Last software reset code".

    With crashes I mean that everything freezes, web interface showes 100% progress and then everything freezes.
    I have noted that if I wait a couple of seconds then I´m able to disconnect and then reconnect and when I run M122 these are the resets codes:

    The software reset code info at https://duet3d.com/wiki/Error_codes_and_software_reset_codes indicates that a software reset occurred because the firmware was trying to write debug info or other essential info to the USB port, but writing was b!Locked because the port wasn't connected or the program at the other end had stopped reading data from it.. This should only occur if you enable debug output using the M111 S1 command.

    Assuming you do not have the USB port connected, I suggest you connect it to a PC, load Pronterface or another USB host program, and connect to the printer. Then do something that normally provokes the problem and see what messages appear on the PC.

    Pronterface messages this:

    Unfortunately, that doesn't help because Pronterface has reported an exception in its own code without displaying the rest of the data. Do you have Arduino (any version) installed on your computer? If so, please try the same test again, but with Arduino Serial Monitor connected to the COM port that the Duet provides instead of Pronterface.

    Also please check that the software reset code reported by M122 is the same as before.

    The seriell monitor shows this at start up and then nothing more:

    Done!

    Same software reset code is reported as before when running M122
    Also tried removing all M570 since the monitor said it´s no longer supported, didn´t help

    This one has me puzzled. You reported software reset code 0x5004. This means that the Move module was executing at the time and it was stuck in a spin loop for too long while waiting for the USB output buffer to clear. For that to happen, Move or DDA debug output would have to be enabled, but the USB would either have to be disconnected or the program at the other end not receiving. The error from Pronterface suggests that it did receive something (that it didn't understand). The serial monitor output shows that the connection was working when the Duet started up. But there are a couple of odd things: it has started up as an access point (i.e. not connected to your router), and it hasn't printed the whole of the access point name - it should be "duetwifi" not "duetwi". It's as if the USB connection stopped working at that point.

    When it freezes I actually loses the contact to the board and needs to restart/reconnect.
    Could it be something wrong with the firmware installation on the board?
    Wondering if it would be a solution to reinstall everything?
    I have 1.17c (2017-01-14) installed, thought it would get better to upgrade but it actually got worse.
    Before the upgrade I only had problem when I used T1 but now I experienced more freezes also when using T0

    Please upgrade to firmware 1.17c+2 (in the Edge folder in github). Connect the serial monitor as before. If you still get the same problem, please check for output on the serial monitor, also run M122 and report the software reset code, along with the additional parameters displayed with it.

    The whole text from the serial monitor doesn´t always shows, stops at duet or duetw sometimes

    Noted a strange thing, when the interface freezes I can move the head with the machinecontrol but I can´t send M122, I need to disconnect and reconnect to do this.

    Thanks. That's a different software reset code - 0x1004 instead of 0x5004. It's still taking too long in the Move module, but this time it's not doing USB output. So I think the USB output flag last time was a red herring.

    Please provide your config.g file, also your tool change files if you have any.

  • I think I solved the problem but I don't know what the problem was.
    Used a friends config file, that has built a almost exactly the same printer as mine, and it worked.
    The only difference in the configs was that I used two M92, one for the axis and one for the extruders.
    And we had the codes in a different order.
