My first suspicion would be the teflon part like Geert said, because printing at 140% is not normal. Did you ever look at it? If it is dark and burned the shape could be deformed and become an obstruction for the filament. For the first layer you could also print a bit hotter and then dial it back to your preferred temperature.

you could do this with the post processing script' pause at height'. Look for Extensions (top bar) - Post processing - Modify Gcode - pause at height. Unfortunately the pause movement to the desired corner location, by default 190--190 is not immediately visible in the layervieuw. Load the created code to see the result.

een goed startpunt is https://ultimaker.com/en/resources/manuals/software waar alle manuals, tips and tricks en video's staan. welke printer gebruik je? voor de Ultimaker 2 staan de materiaal settings, de retraction en de flow rate in de printer zelf. Als je ze in Cura wil veranderen moet je overschakelen van Ultimaker 2 naar Reprap.

Do like it the support mesh lot and very useful. What I don't understand is: in the 'select settings' are the settings available for this function, but since the latest changes you cannot change the support density and the pattern in the support mesh any more. It inherits the settings on the right under support, but most of the time is this disabled because the mesh support is used instead. The only way to change this is to enable support (is not wanted), change the settings and disable support. Do I miss something? Also in the 'select settings' is 'generate support'...... That is what the support mesh does.... Don't see something changing toggling it on/off.

did you move the layer slider to look at the layers from top to bottom? I noticed that sometimes after a change is made in the settings the model is grey until you move the layer slider. Is this what you mean?

I would ad a cube/rectangle to the build plate and scale it so it supports all the spheres and use the 'per model settings' to give it the support settings you want. This way the support is one piece instead of multiple towers.

place a cube or something on the build plate somewhere and scale it very small, too small to print, like 0,1 x 0,1 mm.

what also works very well is to have the support with a sparse infill, with a support interface and then, like gr5 said, pause the printer at the top of the support interface. Use blue tape on top of the support interface, the next layer will adhere better then with oil I guess. The separation is easy..

waar je ook even naar kunt kijken of het kleine zwarte wieltje in de feeder normaal draait. Deze kan nog wel eens beschadigd zijn (niet rond) of klem zitten. Een andere mogelijkheid is je witte coupler in de printkop controleren, als deze wat ouder is kan deze aan vervanging toe zijn.

Fuhre ein -z Wert ein so das dein Model im Bed versinkt. Leider nur in mm, nicht Layer zahl, mit umrechnen vergesse die erste schicht wert nicht. (Put in a -z value in the move section so the model sinks into the bed. Only in mm, not in layer amount, don't forget the first layer thickness if you recalculate for the layer amount )

the top picture is 3.1, the bottom picture 3.2, showing the differences between the 'per model settings' The per model settings override the settings on the right, so your WaterCan settings are set in the main window, could be that you need some support higher up as well. I am really curious what the 3.2 result is with the adaptive layer heights, it chooses the best layer height compared to the angle of the model, and saves a lot of time. Don't know why the support doesn't show in your Cura, but you might want to try out the beta..

it is called 'draft shield' for a single extruder

something is different in 3.2 compared to 3.1 with the 'per model settings' for support. In 3.2 the options to choose from changed, and selecting 'print as support' should be the way to go, In 3.1 you can choose 'generate support' and 'cutting mesh' and it generates only support underneath the bottom curve. I load two separate models, don't merge them, the only thing is to uncheck 'keep models apart' in the preferences. Selecting both, rightmouseclick, 'center selected models' and using the move and scale tool to your liking. Notice the huge time difference...

and how about using the draft shield, will that have the same effect?

minor detail: the arrow of the mesh fixes is pointing the wrong way.

support is not ideal in this case, it also shows inside the vase....

I understood that some fixing was done for the 'pause at height' setting? Would expect to see a travel movement to the 190,190 position, but still nothing to see... How do you check where the pause takes place? Also because the height is specified in millimeters and must be recalculated in amount layers..

this is a nice model for the new Cura beta 3.2 using adaptive layers... In Meshmixer you can offset your walls to your liking, keeping in mind the nozzle thickness, a multiple of 0.35. I did 0.7. At the bottom you need some support, so I put in a scaled cylinder and used the 'per model settings' 'print as support'. And used the new 'adaptive layers' UM2_WaterCanv25surface-07.3mf

if you look at the model in x-ray view, is everything good? no red areas? It seems that Cura thinks you have another bottom at the top, could be your top ia inside out (displays in red) I cannot duplicate this with a box and these settings..

yes, it is good to have the preview in Cura and the calculated time and material to experiment with. Sometimes you think it can that it can do better but the alternative turns out to have a longer print time or uses more material. And there is reality, like you said, bridging can be surprisingly good depending on a lot of things, same for the gradual infill, it will drop, but who cares, you can't see it. Never tried spaghetti infill yet, can imagine what it does but the preview looks weird.. Hope you can print soon and ask again if you want to know something...

I hope UM changes this because it happens with both PLA/nozzle1 and PVA/nozzle2. Never understood why the nozzle dips in the PLA/PVA when we are supposed to keep it clean... The PLA wants to stick to the bottom of the printhead and gets dragged along as well

here is a tutorial about infill mesh

it is possible to place some support underneath manually, this is done with 'infill support' make a box the same size as the space underneath your indent to the bottom and import it in Cura. You can also import a cube and scale it in Cura. In the preferences untick 'keep models apart' Select the box and use the 'per model settings' (on the left of your screen and select the settings for this box: infill mesh, infill count, wall line count and top/bottom thickness. Set the infill density for your support and set the wall/top/bottom to 0

but is your lower region not connected to the outside? because then you have the same problem when the top layers are laid down. you can experiment with the % of the infill, sometimes 5% is enough to keep everything in place.

what you ask is what you get... nothing underneath... did you try the infill? Default is 20%, enough to support a flat area.
