Endstop Question



  • I am new to the duet platform and reprap firmware. I am very comfortable with Marlin firmware. Here is what is going on. I recently purchased a duet 2 wifi and wired it to my Ender CR-10 v2 that was working with the stock ender controller. I also have a bltouch wired onto the printer.

    The duet had firmware 2.05.1 and I immediately upgraded it to firmware 3.0 then to 3.1.1. I then ran the web configurator tool to generate my zip file, which I uploaded to the board.

    I am just trying to get the basics working and I can't get the endstops working. I wired in the NC end stops and the led on the board is lit when the endstop isn't pressed and turns off when it is pressed.

    The issue is when I type the M119 command I am getting

    Endstops - X: no endstop, Y: no endstop, Z: no endstop, Z probe: not stopped

    Nothing I do makes a change and I am pulling my hair out.

    Here is my config.g file

    @kgrigio Send M115 to the Duet and post the reply. My guess is that the Duet hasn't actually updated to 3.1.1, because your endstop definition looks correct for RRF3, but won't work on RRF2.

  • put M574 into the web ui console and post the output



  • @kgrigio said in Endstop Question:

    M308 S0 P"bedtemp" Y"thermistor" T100000 B4138 ; configure sensor 0 as thermistor on pin bedtemp
    M308 S1 P"e0temp" Y"thermistor" T100000 B4138 ; configure sensor 1 as thermistor on pin e0temp

    unrelated buy you have not configured your thermistor correctly



  • M574
    

    Endstop configuration:
    X: none
    Y: none
    Z: none



  • @kgrigio

    this indicates that your config was not read.

    is the config you posted from your lokal computer or from the duet located in the sys folder ?



  • What is on the duet, at least I think. I uploaded the system files from my configuration zip file. Do I need to do anything once I upload them to make them "take"



  • please go to the web ui

    file managment -> system.

    and click on the config.g file and verifiy that they are identical



  • What I pasted above is from the file management -> systems -> config.g file, but I just figured it out. When I opened the file, I then hit save and it now works.

    This begs the question, when I upload a new configuration.zip file why wouldn't this automatically save and start being used? Do I need to go in and save every time I upload? Do I need to save all the files?

    you need to restart the duet to read the initial configuration. when editing the config.g after saving it will ask you to do so.

    so any config changes require a restart.



  • Perfect. Thanks for the help. Now on to fix the other items, like the endstops you pointed out.



  • @kgrigio

    has the output of M574 changed?



  • Yes, now I am reading as follows

    M574
    Endstop configuration:
    X: low end switch connected to pin xstop
    Y: low end switch connected to pin ystop
    Z: low end Z probe

    On the thermistors you mentioned above. What didn't I configure correctly? I haven't looked at this closely yet as I am going between this and helping my kids with virtual school today. Thanks again for the help.



  • @kgrigio

    B4138 is the default. that type of thermistor has not been used in years.

    you need to figure out which thermistor is used in your printer.

    creality tend to use epcop 100k thermistors.
    https://github.com/MarlinFirmware/Configurations/blob/import-2.0.x/config/examples/Creality/CR-10 V2/Configuration.h
    and marlin uses that as well.

    so try the values from this guide
    https://duet3d.dozuki.com/Guide/Ender+3+Pro+and+Duet+Maestro+Guide+Part+2:+Configuration/38
    but use R4700 for the duet wifi



  • Perfect. Thanks.
