New Duet Owner Z issues etc.



  • Good evening folks... First time poster.
    So a friend of mine just sold me a duet wifi, so Ive been spending some time setting it up.
    I have a CR10, so it took a bit of work.
    I am NOT smart haha, but with a lot of help from friends, I may have gotten close.

    ok this is a bit of a weird question too... Before I set my Z position to 0, i had it set to 400... when I had it set to 400, i could use the UI to send. -25 to the printer, sending it up to 375

    However now that i set Z to 0 I cant use the +25 or +5 or whatever without the Z drilling in to the end stop.
    I cant use minus or plus, once its at Zero... all bad.

    Also, it seems when I test a print, my Z doesnt seem to move up much, if at all.

    1. Over extrusion... I am using a .5 nozzle and its working well, but it seems WAYYY to overextruded. I havent done a calibration... I will need to do that, just looking for the best way.
      Btw, here is my config.g.

    M552 S1 ; enable network
    M587 S"" P"*****"
    M586 P0 S1 ; enable HTTP
    M586 P1 S0 ; disable FTP

  • Hi @dunginhawk

    I'm configuring a CR-10 with Duet Wifi I'm learning but I think I can help you.

    Your Z step is wrong, if is a stock CR-10 it should be Z.400, change it and see if is better.

    What extruder are you using?
    If is the stock extruder the starting steps should be E93.00, and then do a calibration.

    I'm using the SEEMECNC EZR STRUDER and I have E119.88
    The E420.00 is for a 3:1 gear reduction extruder like a Bondtech or a Titan

    Here is my config.g

    Like I said I'm learning as well and maybe we can help each other

    I leave here the settings I took from Marlin firmware from my CR-10

    //// MOVEMENT SETTINGS
    #define NUM_AXIS 4 // The axis order in all axis related arrays is X, Y, Z, E
    #define HOMING_FEEDRATE {50*60, 50*60, 4*60, 0}  // set the homing speeds (mm/min)
    
    // default settings
    
    #define DEFAULT_AXIS_STEPS_PER_UNIT   {80.000,80.000,400.000,93.00}  // default steps per unit for Ultimaker
    #define DEFAULT_MAX_FEEDRATE          {500, 500, 5, 25}    // (mm/sec)
    #define DEFAULT_MAX_ACCELERATION      {500,500,100,5000}    // X, Y, Z, E maximum start speed for accelerated moves. E default values are good for skeinforge 40+, for older versions raise them a lot.
    
    #define DEFAULT_ACCELERATION          500    // X, Y, Z and E max acceleration in mm/s^2 for printing moves
    #define DEFAULT_RETRACT_ACCELERATION  500   // X, Y, Z and E max acceleration in mm/s^2 for retracts
    
    // Offset of the extruders (uncomment if using more than one and relying on firmware to position when changing).
    // The offset has to be X=0, Y=0 for the extruder 0 hotend (default extruder).
    // For the other hotends it is their distance from the extruder 0 hotend.
    // #define EXTRUDER_OFFSET_X {0.0, 20.00} // (in mm) for each extruder, offset of the hotend on the X axis
    // #define EXTRUDER_OFFSET_Y {0.0, 5.00}  // (in mm) for each extruder, offset of the hotend on the Y axis
    
    // The speed change that does not require acceleration (i.e. the software might assume it can be done instantaneously)
    #define DEFAULT_XYJERK                20.0    // (mm/sec)
    #define DEFAULT_ZJERK                 0.4     // (mm/sec)
    #define DEFAULT_EJERK                 5.0    // (mm/sec)

    They are for an Ender 3 and Duet Maestro, but the CR-10 and Duet Wifi is very similar for setup.



  • hmmatos...
    so your extrusion multiplier seemed to be spot on.. ill roll with that..
    changed the Z400 as well.

    i dont know why, but my Z is not going up between layers... the stepper is moving for the first layer or two, but then as soon as it moves (i can see the stepper move) it basically rocks back in to its current Z position. Obviously it should go up, (steppers move counter clockwise) each layer, but after 1-2 layers, it rocks back and ends up not moving up at all.
    thoughts on that odd behavior?



  • @dunginhawk does the z axis work if you manually run it all the way up?



  • @Phaedrux Yes, i can run it all the way up manually...



  • Its just so weird... the first 2 layers seem to go fine, maybe the third too... after that it starts rocking back and forth. like it increments up the layer, then drops.



  • it may be stripped out my coupler... because my threaded rod is rising... ordered some new couplers. will test wednesday



  • Hi @dunginhawk,

    did you change de Z step?

    My E step is for the SEEMECNC EZR, what extruder are you using?
