  1. @GregValiant.

    I hope there is a bug in Cura.

     

    I have attached the image with details.

     

    Cura Preview shows Skirt is assigned to Right. But Simplify3d clearly shows that Skirt is with Left.

     

    @GregValiant As per your suggestions, I tried the following:

    Skit/Brim changed from 'Not overridden' to 'Extruder 2'.

     

    It worked. Print started with Right only. Thank you 🙂

    Looking at this some more, there may be a bug in that.  In an example slice I'm getting:

    • Model set to T1
    • Gcode correctly starts with T1
    • The "T{initial_extruder_nr} comes back as T0 and never changes to T1.

    That would appear to be wrong.

    To make it correct either:  Extruder 1 needs to be disabled, or, the Bed Adhesion Extruder needs to be explicitly set to Extruder 2, or, the Bed Adhesion must be set to "None".

    Thanks. 

     

    The "T{initial_extruder_nr} comes back as T0 and never changes to T1. Yes, I also tried. It came to T0 only

    I will assume that you have the LEFT 2 and RIGHT 1 set correctly so LEFT is T1 and RIGHT is T0.  It is easy to confuse that.

     

    Since you aren't calling out Tool# or Temperature in your StartUp Gcode, Cura should set the Tool# and Temperature just in front of the startup gcode.

    In your "Case 1", there should be a T1, and no other "T" lines before the start of the skirt/brim/raft.

    If that is true and there are no "T" lines and the printer is starting with T0, then the firmware may be configured to always start with T0.

    Try changing the startup gcode to:

    G28

    G29

    T{initial_extruder_nr}

    The curly brackets are required.  Cura will replace the keyword with the "Initial Extruder Number" which in this example would be "1".

    It's possible that with T0 enabled that Cura has assigned a couple of lines of the skirt/brim/raft to T0 and so the Initial Extruder Number will actually be T0.  In that case it should have heated up.

    At any rate, it's something to try.

    In your "Case 1", there should be a T1, and no other "T" lines before the start of the skirt/brim/raft.

    If that is true and there are no "T" lines and the printer is starting with T0, then the firmware may be configured to always start with T0.

     

    I tried with Simplify3d. It works flawlessly. If I select T0, Left will start printing.

    T1 is for Right,

    T2 for Duplicate etc

     

    This issue is there since 2 years. 

    I hope Cura is not compatible for IDEX machines yet.

  3. Hello All,

     

    Using Cura 5.3.1

     

    Custom machine with IDEX configuration. Using Reprap Firmware (RRF).

     

    In Printer settings, selected Gcode Flavor as Reprap.

     

    Start Gcode is only G28, G29

     

    When we want to print only with the Right extruder, it is becoming very difficult. We tried various options:

     

    Case - 1:

    Select the object for the Right extruder. Slice it and print.

     

    Gcode shows as T1, but after G28 and G29 it started printing with T0 without heating.

     

    Case - 2:

    Disable Extruder 1 (Left)

    Select the object for the Right extruder. Slice it and print.

     

    Gcode shows as T1, but after G28 and G29 it started printing with T0 without heating. 

     

    Case-3:

    Disable Extruder 1 (Left)

    Select the object for the Right extruder.

    In the Right extruder Print setting, change all from 'Not overridden' to 'Extruder 2'.

    Slice it.

    Only in this case, it was working.

  4.  

    I would like to slice a pyramid such that I want a layer height of 0.2 mm for first half of the total height (base) and 0.1 mm for the remaining half (Top) of pyramid for smooth layers.

     

    Note: I have tried Adaptive layers technique but that’s not what I want.  I have seen that I am only able to change some parameter like infill, line width etc. with the help of Support Blockers option.

     

    It would be very helpful if you let us know if this option is available here in Cura. If yes, also please inform me how to use it.

  5. I would like to view the preview in cross sectional Views w.r.t planes including mentioning the distance of cutting planes w.r.t Reference planes (co-ordinate system), so that I can know at what height I should stop or pause print at require height (cutting plane distance from cross sectional View). This feature is available in Simplify 3D. It would be very helpful if you let us know if this option is available here in Cura too. If yes, also please inform me how to use it.

  6. I am unable to find stop/end printing at height feature, but I can  only find pause at height feature. Stop printing at certain height Feature is available in Simplify 3D but not in Cura. It would be helpful if you let us know that if this feature is / not available in Cura. If available, also help us by explaining how to use it.

     

    Note: I have tried using pause at height feature by adding end G codes at that height condition, but it is pausing just for about 10 sec and starting next layer of print. Is there any solution for this?
