Non-solid solid bottom...

Hi,

 

I've been trying to print those fine cups of Joris. The walls come out perfectly but usually the cups won't hold water because the bottom is not solid. What could cause this?

You are under-extruding, so the lines in the bottom don't match up properly. THis could be due to an incorrect filament diameter setting in your slicer. (e.g., using 2.89mm when your filament is really 2.8mm). It might also be due to printing very fast (which can induce a little slipping in the extruder). Or alternatively it could be due to using a Cura with a wall-width that isn't an exact multiple of your nozzle width settings.

A work around might be to make the base thicker so there are more solid layers printed.

What settings are you using? (Wall width, nozzle width, speed, temperature, layer height. Also, are you using the 'Joris' setting?

Thanks for the tips. I tried to change the filament size and it got a little better, but it still seems that the lines are too far from each other in the bottom layers.

Layer heigh 0.2, Wall thickness and bottom/top 0.8, print speed 50, temp 225, joris activated.

I recommend some over-extrusion with 2.7mm filament thickness. And setting the "extra bottom wall thickness" to 15 in the expert settings also will help against leaking in the corners.
