Why does my UMS5 extrude in the air?

[AlekLKL 0]

Hi!

 

My Ultimaker S5 suddenly started extruding in the left corner and i pulling it back on my print - sometimes it result in a unusable print...

 

It does it the same place, layer by layer.

 

There is nothing there, in my Cura setup.

I have set my UMS5 back to factory settings, but it did not help.

 

I have attached pictures of the line that goes trough my print (is .

 

Have anybody else tried this? I cannot find anything similar.

 

Thank you!

what is the function of the three posts in the print?

The print is for a silicone candle mould - the posts is for wick holes in the mould.

The printer also starts extruding when they are not there.

 

It always starts extruding the exact same place, at all types of prints.

Pretty sure you are printing with a too high temperature. which courses stringing.

The mid air print is probably som structure part that ditten stick to the build plat, and then the printer still tries to print it "in air" or again just extreme stringing that gets deposited somewhere along the printhead travel route.
