Failed Print


Recommended Posts

Hello everyone,

Here is my question.

I saw so many awesome phone cover prints, that i had decided to print my own as well.

I was trying to print a phone cover on my Ultimaker Original +. After one hour of printing my printer failed like always...

Here are the results of printing after an hour.


And this was the support..


Here is the file that I was trying to print.


Here are the settings that i have used for printing the file.


My prints always fails if it's big size. I have no problem with little ones. I guess my problems is somewhere there but i can not figure it out what the exact problem is. But I am not sure if that could be the main problem..

If something is not clear enough just ask me. I hope that I explained the situation very well and hope someone could help me.

With kind regards,

    I can see a few problems.

    Your speeds vary a LOT, Its best to keep all these the same. There are a few problems when you have them change like that. 1 being that it ends up printing to fast or slow for the nozzle temp. So you may get under extrusion on the infill but over heat the outer shell.

    2 being that the x/y reaction time is a lot faster then the filament being fed through the bowden so you can end up with fat area of the line its putting down. (hope that makes sense)

    It also seams that you item wasn't sitting on the glass. you don't need any support if its lying on its back. so turn this off and make sure the model is sitting on the glass.

    Your view in cura is standing up. will it print this way or is the bottom curved?

    if you print it standing up then rotate it 45deg angle as it will print nicer this way.

    Your layer height is 0.2mm and you top bottom thickness is 0.6mm this means it will only have 4 layers to cover the infill, its best to have this at 6-8 time the layer height. especially if your infill is 10%

    20% infill is normal so your could try that.

    You can also set the bed temp to 60deg.

        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.
