Incorrect print estimate DWC.

  • Hey guys. I upgraded my DWC. I need to update my duet, which I'll be doing this weekend. The issue that I'm having is that DWC isn't showing the correct file progress in the progress bar. I have my gcode set up to move the bed near the max limit (CoreXY so the bed lowers all the way) and it seems that this is messing it up. Before I upgraded DWC this worked fine, but now I have issues with it.

    Under software info it says:

    Firmware Version: 2.01 (RTOS)
    Wifi Server Version: 1.21
    Web Interface Version: 1.22.3

    Maybe if I update my duet this will all be fixed?

    Can you post a sample gcode file? Or at least the first 50 lines or so? I'd like to see what your start gcode looks like. As you say, the large z move may be messing it up.

    What slicer are you using?

    If you upload this zip file to the settings tab on the DWC it should update your firmware, wifi server, and DWC to the latest stable release.

    I don't know that it will make a difference though. One work around that does work is to move the offending part of your startup gcode into start.g which gets run when a print starts before the slicer start gcode does, and since it's outside of the print gcode file the z move doesn't get parsed.

  • Prusa Slicer, V2.00. Thanks for the link. I'll update that tomorrow.

    @surgikill said in Incorrect print estimate DWC.:

    Prusa Slicer, V2.00

    That would explain it. There was a change in their formatting. It's been fixed in 2.03 RC4+

    So you can either upgrade to the release candidate for 2.03 or wait a few more days for the final release.

  • @phaedrux If I want to flash the release candidates, can I download the combined firmware for RC5, or should I only go to 2.02?

  • Moderator

    I'd probably start with 2.02 zip file so you have the right wifi server and DWC files. Then update to the 2.03 RC5 firmware.

  • @phaedrux I see you have a coreXY printer. I was reading that the core kinematics changed in 2.03. Any tips for swapping over?

    @surgikill for me everything just worked, nothing had to be modified in the config, so I didn't really dig into it further. But it's never a bad idea to take it slow when testing a new firmware update.

    I have a macro that drops currents and allows movement without being homed so that I can test motor movement with a few small jogging moves before trying to even home the printer.

  • @phaedrux Can I get that macro? I haven't delved completely into everything yet. The printer still isn't completed from the hardware side so I haven't bothered to customize the software too much.

    @surgikill I'm mobile right now but it was a pretty simple macro

    M913 to drop the currents.
    The mcode to allow movement without homing
    Then a sequence of m291 commands to pop up axis jogging prompts one after the other just to make sure they move in the right direction.
    Then another m913 to return current to normal.

    ; Quick motor testing
    M913 X35 Y35 ; drop motor current
    M564 S0 H0 ; allow movement without being homed and allow movement outside limits

    M913 X85 Y85 ; return motor currents to normal
    M564 S1 H1 ; restrict movement of unhomed axis and prevent movement outside limits

    If motors still move correctly, test homing.
