dual extruder setup



  • I'm working on a custom printer with the duet 3 and dual slice mosquito magnums. I've selected everything to do with dual drives,fans, heaters, two tools ( one for each print head) etc.
    When I turn on the printer/screen Only one extruder shows up. Is that normal? I feel like two should show up for manual control.

    Yes both tools should show up in DWC. Try running M98 P"config.g" to see if any error messages are reported. Btw the T value for the Slice thermistor is 500000 not 50000.


  • Moderator

    Can you verify that your firmware version and DWC version is 3.1.1.?



  • @dc42 I"m running it in standalone mode since i have a new duet3 board- when i did the online reprap configuation i selected the duet 2- Pretty sure i read that i need to do that for standalone mode right? Should i try the m98 p "config.g" in yat? I also don't have the motors and stuff hooked up. i was just trying to get the firmware aspect ready to go. that shouldn't matter right?

    I'll change the t value good catch



  • IMG_6257.jpg IMG_6256.jpg

    Also while hooking up the panel due i checked the pin out and the none of them lined up. the 5 volt line on the panel went to the ground pin on the board. the ground was on a different pin etc. so the panel didnt turn on at all. I put the pins in right location and it started working. the difference between these two images is the IO in and outs being switched. I assume the "out" of the panel should be going to the "in" of the board and vice versa for the other In/Out\

    as you can see it changes if it connects and gets rid of the temp of the extruder



  • @Phaedrux 3.1.4 according to the config file


  • Moderator

    3.1.4 is the version of the config tool.

    Send M115 to get the version of the firmware. For DWC version, check the settings page.

    No, you must still select Duet 3.

    No, choose Duet 3. There is a checkbox for standalone right below the board drop down for Duet 3 "Run in standalone mode without SBC"

    If you have a Duet 3 your config will not work because all of the pin names refer to Duet 2. So you'll need to generate a new config.



  • @Phaedrux FIRMWARE_NAME: RepRapFirmware for Duet 3 MB6HC FIRMWARE_VERSION: 3.01-RC9 ELECTRONICS: Duet 3 MB6HC v1.01 or later FIRMWARE_DATE: 2020-04-21b1<LF>ok<LF>



  • @dc42 I redid it with duet 3 this morning and selected the standalone mode. fixed the thermistor value. the diag led light stays flashing, the panel due will stay on the "connecting" mode unless i swap the in/pins like i mentioned in my previous comment.
    with out all the motors and what not selected the hot ends should still show up as if they are there and the connecting should switch to busy or ready?



  • @Phaedrux yup- i redid it this morning already- see my response to DC

    Update your firmware first off.

    Upload this zip file as is to the /sys folder in DWC
    https://github.com/Duet3D/RepRapFirmware/releases/download/3.1.1/Duet2and3Firmware-3.1.1.zip

    The diag light will pulse steadily in normal use.

    The paneldue should say idle when it is connected and ready to go. You will need M575 P1 S1 B57600 in your config.g to enable support for PanelDue in recent firmwares.

    Post your new config.g.



  • @Phaedrux Do i have to be using web control for this with standalone? Right now it's not an option due to no ports- I'm at work. I could find a longer cord and go to the next room if need be.
    if not do i just unzip that folder into the SD Card into that same directory?



  • @Phaedrux
    New config file. it just reads busy and the temp boxes for the extruder are gone unless i switch the two io pins. then they come back but it sits on connecting

    Yes.

    You could do the manual firmware update process if you only have access to the board via USB terminal. Extract the zip file, copy just the firmware bin file to the SD card in the /sys folder. Connect via USB and send M997 S0.

    https://duet3d.dozuki.com/Wiki/Gcode#Section_M997_Perform_in_application_firmware_update

    For the DWC files, download this zip file and extract it to the /www folder

    https://github.com/Duet3D/RepRapFirmware/releases/download/3.1.1/DuetWebControl-SD-3.1.1.zip

    Once you are updated, send M115 to confirm and then try sending M98 P"config.g" and report any errors.



  • @Phaedrux i downloaded that zip folder and unzipped it and they're mostly .gz f files and nothing named firmware.bin or similar.
    Should i be downloading this firmware bin from DC's github?

    https://github.com/Duet3D/RepRapFirmware/releases/download/3.1.1/Duet3Firmware_MB6HC.bin



  • @Phaedrux
    ok so i unzipped that same file again and now a bunch of .bin files are showing up. I'll copy the duet 3 mb6hc to the sys folder and do the m997 etc



  • @Phaedrux copied the Duet3Firmware_MB6HC.bin into the SYS folder, did the M997 S0 and its give me this error
    Error: M997: Firmware binary "Duet3Firmware_MB6HC.bin" not found<LF>ok<LF>

    It would be substantially easier if we had network access to DWC.



  • yeah I'll have to get IT involved for that though. Why do i need to update the firmware for a brand new board though? Shouldn't it still work.
    I do have a Ethernet to USB connector for a PLC but that was a pain to figure too. probably not worth the hassle.

    There have been many improvements and fixes for RRF3 between the release candidates. Version 3.1.1 is the latest nad has been proven to be quite stable. So it's strongly recommended to update just to eliminate any potential problems that have already been fixed.

    Just in case there was something wrong with the file, try downloading this one

    https://github.com/Duet3D/RepRapFirmware/releases/download/3.1.1/Duet3Firmware_MB6HC.bin

    Compare the size. It should be 557 KB. Make sure it is within the /sys folder.

    Also, just to make sure you have all the other required files present, download these from the 3.0 release and place them in the /sys folder as well.

    https://github.com/Duet3D/RepRapFirmware/releases/download/3.0/Duet3iap_sd_MB6HC.bin

    https://github.com/Duet3D/RepRapFirmware/releases/download/3.0/Duet3iap_spi_MB6HC.bin

    https://github.com/Duet3D/RepRapFirmware/releases/download/3.0/Duet3_SDiap_MB6HC.bin

    When you have all those files in place in /sys try M997 S0 again.


  • Moderator

    Otherwise your new config looks alright. I'm not sure of your hardware so I can't say if it's all correct or not, but you should be able to do some commissioning testing.



  • Going to get IT to hook it up to the network and go form there.



  • @Phaedrux Good news- after much formatting and getting the card to read and what not it's finally working on dwc. both hot end showing up, sits at idle.
    followed the update firmware from the settings menu and selected the file you posted and i still get

    M997 S0

    Error: M997: Firmware binary "Duet3Firmware_MB6HC.bin" not found

    I tried putting all 3 of those files in the /sys folder too and put it back in the board and same thing.
    I may just leave it until i get the rest of the printer built and hooked up and see how it runs?
