extruder works but print not starting



  • Hi,

    I am using Duetwifi with Titan Extruder my printer homing x,y,x successfully and the heater heating up to the printing temp
    it shows that the printing is in progress but no print at all
    i got a message Filament n/a layer n/a
    help please!!

    Thanks,


  • administrators

    Have you tested extrusion, and calibrated the extruder steps/mm?



  • @dc42 Hi Dave

    I did but i edited my config files and uploaded many time after i calibrated the extruder
    do i need to re-calibrate it again?
    in simulation of print it works but when i try to print it heat up and home axis and looks ready for printing but not moving , and shows in duepanel and web interface the print time is going on but change in x,y,z or E steps.



  • Can you post the first 50 or so lines of a gcode file you're trying to print?

    Can you also post your config.g?

    Where does the A0 come from?

    It would appear that you are missing a tool select command anywhere. Without it, the hotend won't be enabled. Try adding T0 to the end of your config.g to enable it at startup. And add T0 to your Cura start gcode. You should probably also change Cura to use RepRap flavour gcode. I think if you do that it will add the tool selection itself when it sends the temp commands.

    Do you have a part cooling fan? The way it is configured now all fans are thermostatically linked to the hotend.

    Typically Fan0 would be used as the part cooling fan and Fan1 for the hotend. Fan2 possibly for cooling the duet.

    For example, here is how I have it configured.

    M106 P0 S0 H-1 C"Part Cooling"     ; Set fan 0 (Part cooling blower) G-code controlled. Thermostatic control is turned off
    M106 P1 S1 H1 T45 C"Hotend Fan"   ; Set fan 1 (Hotend fan) Thermostatic control. Turns on when hotend reaches 45c

    Don't forget to calibrate the trigger height for your zprobe.

  • @phaedrux many thanks
    I will do these modifications and check



  • I think the problem is with remapping the Extruder to driver "6" (E3) on duex2
    but when reconfigure it again to driver"3" it works but the independent Z homing macro not working!
    the macro was working fine when i map drivers 2,3,4 and 5 to Z with virtual axis U,V and W.
    any help please how to sort our this issue?

    Thanks,


  • administrators

    1. Is your config.g file the same as in your post of 15 August?

    2. Did you make sure that Tool 0 is selected, either in your slicer start GCode or before you start a print?



  • @dc42 Yes it is the same config

    I am wondering whether the stepper driver 6 output could be faulty. Can you try driver 7 instead, if it is a DueX5 not a DueX2? Alternatively, test driver 6 by e.g. connecting the X motor to it and using X6 in the M584 command instead of X0.



  • Unfortunately i have duex2 the driver is working when assigned to stepmotor not extruder.
    May be if i ordered duex5 would be a solution or this may be bug with the firmware?


  • administrators

    No i don't think it's a firmware bug. Please try removing E6 from your M584 command and changing X0 to X6 in it, and with the Duet powered down move the X motor connector to the E3 connector on the DueX2. Then power up and test the X axis. That will show whether the E3 driver (driver 6) is working correctly.



  • Hi Dave , I remapped the driver 6 to x and it is working now.
    i will check the printing today.
    I have another question I am testing PNP sensor LJ12A3-4-Z/BY and i did the static testing and it give me 1000 in in DWC.

    G90 ; back to absolute mode
    G1 X100 Y100 S2 F2000 ; put head over the centre of the bed, or wherever you want to probe
    G30 ; lower head, stop when probe triggered and set Z to trigger height

    I used the code of Homing Z using a Z min endstop switch in homez.g
    and looks working i dont know if bed probing will work or not herein my code

    I have another question I am testing PNP sensor LJ12A3-4-Z/BY and i did the static testing and it give me 1000 in in DWC.

    Is the reading 1000 when the sensor is close to the bed and triggered, or when it is far from the bed and not triggered?



  • Reading 1000 when triggered and sensor indicator led on
