SOLVED BondTech CR-10S Extrusion Problem



  • Hi,
    I just finished upgrading my CR-10S with Duet 2 wifi. Tried to do 1st print and failed miserably.
    When its printing, i cant see any filament being extruded. the gears are moving but nothing, and i also hear clicking sound from my extruder. Im so confused on what is going on. Esteps calibration using G1 E100 F100 works well. Using the extude button from the web-interface also works well. Checked the flow when calibrating Estep and i can see its not clogging. Infact its so smooth. It only happens when i try to print something. Im using PrusaSlicer with RepRap as the G-code flavor. Can anyone help me fix this? My extruder are working fine if its not printing. FYI : tried Simplify3d too. same issue.



  • post your config. what temperature are you printing at?

  • Print Temp is the same as to when i calibrate Esteps. so i dont think is not hot enough.

    as to why i have 2 Z settings. if i dont do it like this. my extruder wont even move.



  • @Kaizer I can see why you need to set two Z drivers. You have defined the extruder to use drive 4 in your M584. By default the first extruder (extruder 0) would be drive 3 and the second extruder (extruder 1) would be drive 4. Now in your tool definition you use drive 0. So if you don't define drive 3 as anything, then the firmware reverts to it's default and sets extruder 0 as using drive 3 so your extruder on drive 4 would become extruder 1. In that case, your tool, definition (M584) should use D1 not D0.

    So you have several options. The simplest is to move the extruder to drive 3 and set the Z to only use drive 2. Or, if you really want to use drive 4, define the tool to use D1 not D0.

    As for no filament coming out when you print, you probably just need to have a T0 command somewhere to select a tool. Either at the end of your config.g or in the slicer start code.



  • Do you your slicer set to relative extrusion and 1.75mm filament dia?



  • @Kaizer said in BondTech CR-10S Extrusion Problem:

    M305 P0 T100000 B4138 R4700 ; set thermistor + ADC parameters for heater 0
    M305 P1 T100000 B4138 R4700 ; set thermistor + ADC parameters for heater 1

    also you are most likely printing at the wrong temperature. B4138 is the default and most likely wrong for your thermistors.



  • @deckingman Thanks. It makes a lot of sense now.
    My Slicer start Gcode is only
    G28 ; home all axes
    G1 Z5 F5000 ; lift nozzle

    should i add T0 as u said? if yes can u give me an example of the completed code?



  • @Veti i see, Im actually wondering about it too. but since i dont know much about it. i just leave it as is and do a temperature tower later on.

    Im using the stock Bed thermistor for CR-10S and E3D V6 Tube Thermistor for my hotend. i dont know what their names are so idk what to set my thermistor as. if you know, mind sharing it? thanks.



  • @Kaizer Literally, it's just "TO" on a new line (without the quotes). So:

    G28 ; home all axes
    G1 Z5 F5000 ; lift nozzle
    T0

    or put the T0 first if you need to heat the hot end before homing.



  • @deckingman Thanks alot. will give it a try now.



  • @Kaizer said in BondTech CR-10S Extrusion Problem:

    E3D V6

    if its a genuine E3D the settings are: B4725 C7.060000e-8



  • @Veti Thanks, so its gonna be

    M305 P1 T100000 B4725 C7.060000e-8 ; set thermistor + ADC parameters for heater 1

    ?



  • correct. the r parameter is not required as will be replaced by the correct one for your board.



  • @Veti what do u mean by r parameter? sorry i dont really understand programming language.



  • @Kaizer said in BondTech CR-10S Extrusion Problem:

    M305 P0 T100000 B4138 R4700 ; set thermistor + ADC parameters for heater 0

    R4700. That is optional and not required as its the default value.



  • @Veti i see, Thanks a lot.



  • @deckingman Thanks for the help. it works fine now. 👍 👌



  • @Kaizer Glad you are sorted. ☺
