    I have just successfully printed the hybrid X-Carriage in ABS.

    Apart from s3d having some odd interpretation of "supports" it worked ok, but knowing that ABS shrinks by about 1.5% I just wondered if there is a drawing with dimensions I can check the print against.

    It's quite possible that the absolute dimensions don't matter but it would be useful regardless to have the drawing rather than the stl files as that way it's easy to make your own modifications.

    Good to know things are working well.

    I am printing from just the left extruder on my dual, keeping it simple as I learn.

    So how do I now save my s3d configuration (everything) which works very well, in case I totally mess it up when trying to get the right hand extruder working?

    I want to use a different nozzle size on the right hand extruder so I have more flexibility, especially in speed of printing.

    I have various .FFF files for the left extruder, and I don't have a dual configuration in s3d.

    Can I now create other .FFF files for (just) the right extruder?

    Using the "Export FFF Profile" should backup all the needed configuration settings. If you use "Save Factory File...", you would make a snapshot of your current work environment, including any unsaved changes to the current profile and your loaded print model(s).

    To convert one of your processes to the right extruder, you can open the Edit Process Settings tab, select the process for the left extruder and select "Save as New". Then change the Extruder Toolhead Index on the Extruder tab to "Tool1" and the Temperature Identifier for the Extruder under the Temperature tab to "T1".

    If you have homing and dock for priming in your start script, you would also need to make sure it is using the correct toolhead as reference when it is moving to home and dock.

    My startscript for right extruder only:
    Code:
    ;BigBox Printer Start Script Begin
    
    ;extruder offset - refer to the wiki | http://wiki.e3d-online.com/wiki/Printer_Commissioning#Dual_Nozzle_Alignment
    M218 T1 X35.6 Y0
    
    ;Home
    T0     ;Select Extruder 0
    M117 Homing.
    G28
    G1 Z4
    
    M117 Print Starting.
    
    ;Dock
    G1 X70 Y200 F3000
    G1 X70 Y240 F3000
    
    ;Prime Extruder
    T1     ;Select Extruder 1
    G92 E0     ;Reset E
    G1 E10 F200     ;Extruder 10mm
    G92 E0     ;Reset E
    
    ;Undock
    T0     ;Select Extruder 0
    G1 X80 Y240 F3000
    G1 X80 Y200 F3000
    T1     ;Select Extruder 1
    
    ;BigBox Printer Start Script End
    
    And my end script:
    Code:
    ;BigBox Printer End Script Begin
    
    M117 Print Complete.
    
    ;Dock
    T0
    G1 X70 Y200 F3000
    G1 X70 Y240 F3000
    
    ;Disable Systems

    M104 S0     ;Turn off Hotend
    T0    ;Select Extruder 0
    M104 S0     ;Turn off Hotend
    M140 S0    ;Turn off Heated Bed
    M84    ;Disable Stepper Motors
    M106 S0    ;Stop Print Cooling Fan
    
    ;BigBox Printer End Script End
