Cura and wall

[makingzone 2]

Daid, I've got a question about how Cura generate the Gcode for walls.

i've got a model like a box with wall of 2mm. In Cura, this is my param in Cura :

Nozzle : 0,4

Wall : 0,8

So to make my 2mm wall the Ultimaker avec to do 2 lines for exterior wall, 2 lines for interior wall. So there is 0,4mm left. To make this 0,4mm the ultimaker shake a lot (you can't see it, but you can hear it and fell it) instead of made an other 0,4mm line. These micro vibrations are very annoying because after 15-20 layers it may cause issues (My radial bearings inside the heated head move and left there places. I've to replace it each 10 minutes durring the printing to not fail my print...)

It tires to make that .4mm fill in diagonal lines which is tricky since there isn't much room for diagonal lines (in theory zero room).

Anyway it sounds like you need to redesign your heated bed. Or maybe you just need to change your print speed a bit so it doesn't vibrate at exactly the frequency that is messing up your "radial bearings".
