No brim being produced by Cura 14.07

Posted · No brim being produced by Cura 14.07

Hi, tearing my hair out here, never seen this before. I have Platform Adhesion Type set to Brim and under Expert settings Brim set to 20. There is no brim in the Cura layers view, in the Repetier-Host view, having transferred the g-code and nothing on the print bed.

I have switched the settings to different values and back again and rebooted the PC.

Swapped over to Slic3r and no problem.

Anyone know what is going on?

    What are you trying to print? sometimes the object is not touching the buildplate for whatever reason and the first layer is super tiny.

    Another possible reason is because there is some double/interpenetrating face going on in the mesh and cura can't accurately tell inside from outside to put a brim on.

    Try with just a standard model that you know works. if it slices with a brim then it's most likely some issue with your model.

    Thanks guys, this is the model, the orange one although they are both the same apart from size.

    cuff Jpg.

     

    It gets printed vertically.This evening I discovered that if I turned it upside down - or right way up, there is no top or bottom - I got a brim. Turn it back no brim.

     

    I will check the mesh tomorrow; it was done in Solidworks which is normally tight in producing 100% meshes but I guess you never know. I am sure both top and bottom have chamfered/filleted edges, not that I would have thought that would be the cause.

     

    .300mm all layers including layer 1.

     

    I reinstalled 14.07 but no change. For sure I am sure it is a problem with this model and not Cura never printing brims but the model was printed back in April with a brim and has had two minor mods since then. Maybe it just happened to be laying on the print bed the other way up.

    Loaded the model into InStep and Netfabb and both software reported zero errors, unsurprisingly for a mesh created by Solidworks

    Loaded the model into Cura 13.11, the software used to slice it previously. Discovered it was the same there i.e. one way up gets a brim the other way does not. As said earlier, get a brim in Slic3r irrespective of the orientation.

    Have you tried turning it the way where it doesn't produce a brim and use the cut off bottom option to shave a few mm off to see if it creates a brim?

    No I had not because I cannot really do that for the finishedd product. But a good idea for the detective work. I will try that tomorrow

    do you have something in the first layer where there is no brim?

    Like Valcrow said, there might be something tiny on that side that cannot produce layer information.

    Then it would be a good idea to use the cut off, just a very small amount until you see what you need...

    Yup you don't need to print it, just see at what value does cura decide to make a brim. Then you will know where the problem is.

    In the GCode is there anything in layer 0? It could be that there is a small "spike" at the bottom of your model, causing Cura to generate an empty layer (and thus no brim)

    Hey everyone,

    I just wanted to share my experience. Originally a raft or brim wasn't being generated for my model. After reading through this thread, I checked the layer view and dicovered that the first 5 layers or so of my model were blank. Even after adjusting the cutoff, the blank layers remained. What surprised me was when i looked at the gcode in Repetier Host. The layer view showed that the bottom layers were full.

    This appears to be a problem with Cura not recognising the bottom 5 layers of the model.

    If I cut off .22mm of the "bottom" then as suggested above I get a brim. In theory both "ends" have the same geometry; they have a fillet and chamfer to smooth them. Print setup is with a 1st layer of .3mm.

    Yup you are right Daid, layer 0 is blank; if I inset by .22mm then layer 0 is as expected. I will give the model edge some close scrutiny.

    Interestingly with layer 0 set to .3 I have to inset the model by .22 to get a brim. If I change layer 0 to .1 I have to inset the model by .42 to get a brim. Given that the inset is in mm and not layers, I am not sure I understand that.

      • 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.
