Hi everyone
i am new to diy 3d printer
As i configure through online Repetier Host
i config y_dual motor as Y2 motor to E1
my prob is i cant run the extruder0 motor
even if i interchange the x and extruder motor,motor is working good
But i cant find possible solution for my E0 pins are not enable
in eeprom they is nothing as EXTRUDER0
they is some software issue can anyone guide me
i am using Repetier 0.92 and 1.0

    So E0 is extruder motor that is not working as extruder while E1 as second Y axis is working?

    Extruders only extruder then hotend is hot or you enable cold extrusion using M302 S1. That is the normal mistake in testing condition. Also make sure dry run is not enabled or it will also ignore extrusions.

    I done with M302 S1
    even though i cant run extruder motor
    I am using A4988 driver, its in good condition
  • venkatesh_edwardvenkatesh_edward
    i run with dry run with manually controls
    but motor is not getting energies
  • venkatesh_edwardvenkatesh_edward
    With M302 S1
    G1 E10 F200
    the extruder just tricks as lik energing but not rotating

    - Extruder blocked
    - Current to low
    - Only one coil gets power preventing rotation

    My actual situation
    when i assign the E0 port to X-axis
    intially its not rotating,later i tried by manual input
    G1 X20 F200
    after few sec that means after 10-15sec
    X-axis(E0 port) Motor starts with clicking sound,A4988 driver became very Hot and Motor too became very Hot.
    I have attached X-axis configuration
  • RepetierRepetier
    Motion should be immediately. If everything gets very hot you might have current set up too high instead of low. Then overheat protection turns on/off. There is a point to measure current as voltage against gnd pin. Compare that driver with e.g. x axis. You could also swap x and e0 driver to see if it is then working. If x axis then gets problems the driver is set wrong or defect.

    Thanks a lot,i checked and found out current was too high as 1.5 Amps
    I solved issue
