  1. play with the initial layer thickness until the letters show in the first layer.

    There is also another little trick:

    print the first layer thin with the letters, pause the print, change the colour and resume the print.

    In your case I would start with one thin layer with the letters and stop the print, change the colour, change the first layer thickness to a solid first layer and print over the first layer.

    Info from an old topic:

  2. did you try the little wheel icon next to the 'Experimental' tab to show all the settings visibility?

    Or under Preferences -> settings to check all the needed boxes?

    Or simply type 'fuzzy' in the search settings (fastest option)


  3. when you use ->preferences-> multiple build plates, a little window down left appears, where the numbers are visible and clickable.

    It seams to be a bit of a forgotten, unfinished, but handy feature.... you can click an item in the list and the model lights up, but if you click a model it is not highlighted in the list.. And you cannot drag the window, it is overlapping with the model text

  4. I tested your setup, Cura 4.0 beta: I disabled all wall, top and bottom, only infill (100%, lines, direction 90 degrees)

    set the infill line width to 0.8 (0.8 nozzle) and counted 15 lines.

    No idea what the measure is of the printed part, due to flattening of the plastic...

    I think the best way to get your measurement is to play with the line with values.

  5. ...and.... you can also make your own modified 'brim'. Place a normal cube or cylinder on the bed and adjust the size and height, make the height the same as the first layer and move them to the end of your tubing. They will act as 'Mickey Mouse ears' to hold your model to the glass, without the trouble of removing a complete brim, only remove the ears at the ends.

    (in the preferences disable 'keep models apart')

  6. this could be a lot of things, test the everything from feeder to nozzle:

    Check if the little black wheel inside the feeder is rotating freely, and if the tension is right. When closed, try to pull at the filament if it slips. https://ultimaker.com/en/resources/240-cleaning-the-feeder. Look at the marks on the filament, are they overall the same? Deep or shallow? Are there bite marks?

    Take the print head apart by starting with the Bowden clip and remove the Bowden tube. Heat the nozzle and push the filament through by hand. Also perform a 'cold pull'. Cool the nozzle down to 90 degrees with filament inserted, and with the print head in one corner, pull out the filament. Check what the end looks like: is it dirty, is it thicker than normal? You can do this a couple of times.

    Take the printhead further apart and look at the white teflon coupler. When it is brown, it should be replaced.

    Remove the nozzle and clean it, clean the heater block and put everything back together, tight (not over tight). Check the assembly manual for instructions https://ultimaker.com/en/resources/235-assembly

    Take a piece of filament and push it in from above the printhead and feel if there are any obstructions.

    Put the bowden tube back on, heat the nozzle and load some filament. Turn the feeder wheel and look at the extruded filament, is it a nice consistent flow?

    Start a print....

  7. the easiest way to deal with this is to print the missing part by detecting where it failed, then sink the model in Cura beneath the bed and glue the parts together.

    Even if you could manage it to resume the print, it will be a visible seam, which also happens if you pause and resume a print.


  8. Normally after each print the material is retracted and can be removed manually or automatically cold. Your situation indicates there is something left in the nozzle that sticks, so try doing some cold and hot pulls to ensure everything is clean inside the nozzle.

    Are you using a special filament or the default/normal ones? Or changed filament types?


  9. what would help is when you load the material, feed it manual in the Bowden tube just 2 cm, and not 20 cm like you did.

    What happens is that the fast forward brings the tip of the filament too soon at the nozzle. Just put in the filament 2 cm, close the feeder, let the fast forward transport the filament to the printhead and the last bit is transported slower towards the nozzle.
