using cura for Bfb 3D Touch


Recommended Posts

Posted · using cura for Bfb 3D Touch

Hey after weeks of try and error i finally got the old Bfb 3d Touch from my University to work with cura. But right now i have to change the gcode everytime i use extruder 2.

The Bfb 3D Touch can work with up to 3 hotends, currently equiped with 2 hotends. So far i got it only to work with 1 extruder at a Time, because f the following issue:

The bfb uses the comand M104 {prin_temperature} for hotend 1 and M204{prin_temperature} for hotend 2. But when cura changes the temperature it uses m104 everytime so only hot end 1 is heating.

My fix is currently to edit the gcode when i use extruder 2 and change every M104 to M204. But when i use both extruder at the same time i can not tell wich m104 has to change and wich not.

Sadly it didnt work to implement the m104/204 in the start gcode of the extruder.

Is there a way that cura uses the right m104/204 depending on wich extruder to use next?


Another minor issue i have is, that the flowrate has to set to 4700% and because of that the lines in the prview are so thick that you can not see whats going on. is there a way that cura does not refere to the flowrate for the line thickness in the preview or another way of setting the flowrate to a correct level?

    If there is someone also trying to use cura on a Bfb 3d Touch here is how i managed it to work:

    create a standard fff-printer in cura

    change start gcode to:

    ^Checksum: NO

    ^Time: 1234

    ^Ex1: PLA White

    ^Ex2: PLA white

    ^Ex3: None

    M227 P3200 S3200


    M113 S1.0


    change end gcode to:



    ~M104 S0

    M113 S0.0


    Change extruder 1 Start gcode to:

    ;extruder 1



    ;start extruder 1 extruding


    M104 S{material_print_temperature_layer_0}


    M551 P57600 S600;priming p-extrudingmass s-speedofextrusion




    Change extruder 1 end gcode to:



    Change extruder 2 Start gcode to:

    ;extruder 2


    ;start extruder 1 extruding


    M204 S{material_print_temperature_layer_0}


    M552 P57600 S600;priming p-extrudingmass s-speedofextrusion




    Change extruder 2 end gcode to:



    Printer settings:

    x 395.0



    origin at center

    gcode Flavour

    Bits from bites


    Nozzeloffset x extruder 2 50mm


    Print settings custom expert:

    flowrate to arround 4700

    uncheck infill bevore wall

    Buildplate adhesion :none (Change in flowrate strangly does not apply here so its not extruding the raft until you change it manually)


    slice your stl and save gcode

    open the stl with notpad or simillar

    open an .bfb made with axon and delete everything

    Copie the gcode from cura in the .bfb file and save. This is necessary to avoid an file read error, may be possible to do otherwise.


    At the printer  settings of the bfb you have to uncheck the chek file before printing

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
