upload gcode error



  • ive been uploading and printing fine for the past few days except once in a while it would upload really slow, and then it would fail one here and there.
    now it fails every time.
    just updated the firmware, wifi module, and the DWC.
    running on win7 google chrome
    i also removed the card and checked for errors and defragmentation was at 0%.
    ive only ran about 20 files through it so far.
    i can connect and move the printer fine i just cant upload anything via wifi.

    That's rather a long block write time, so the problem might be wear on the SD card. Try a new SD card, and make sure you format it using 32kb or 64kb cluster size.

    WiFi signal strength -66dBm, reconnections 0, sleep mode modem

    That signal strength is a little lower than ideal, but probably OK.



  • so i reformatted an sd card i had sitting but i think that made it worse, it says my wifi module is connected to the network but DWC wont connect. im gonna buy a fresh card today and try again. all i should need to do is just copy the files from the old one to the new card right? and keep the directory's the same.

    Correct.

    If you are using a 2.0RC version of DWC then I suggest you revert to DWC 1.22.6. I get occasional upload errors using DWC 2.0RC3, whereas uploads are 100% reliable using DWC 1.22.6.



  • okay i got a sandisk ultra 16g, formatted to 64kb and tried an upload.
    it tried for 20 mins and got up to like 90% and failed. ill try reverting to 1.22.6 later tonight. i dont understand how it worked at first but slowly got worse. ill try scooting it closer to the router to be sure.



  • ok so i just took the time to actually look, haha, and i am already on DWC 1.22.6
    should i try updating to dwc2?

    No, I find DWC 1.22.6 completely reliable, but DWC2 not yet.

    I am guessing that the problem is related to signal strength or WiFi interference. See https://duet3d.dozuki.com/Wiki/WiFi_disconnections_and_AJAX_timeout_errors. Note, a small number of WiFi routers seem to be incompatible with the ESP WiFi modules. We don't know why.



  • ill try moving it closer. is there anything else that you think would cause it to slowly degrade?

    It could be that the 2.4GHz spectrum has become more congested where you are. Changing WiFi channel on your router may help.
