[How-To change line width setting mid-print]

Is it possible (I'm sure it is, everything is with Cura) to change the line width value mid print? I.E. if I have an item with 500 layers that prints at 0.8mm layer width, can I change it to print at 0.4mm from layer 400 until the end?

Ended up being a moisture problem. I placed my filament in a dry box for 8 hours, and afterwards when I printed the diagonal lines were gone.

Hello community. I am trying to calibrate a new-to-me filament, and am having a challenge with the retraction tests. As you can see, I am printing the "Retract Distance" towers found in the "Auto towers" plugin within Cura. The one on the left is 1 - 6, and the one on the right is 7 - 12.

 

There is next to NIL stringing at any setting, but what I am seeing is a piece of filament sticking out from both sides no matter what retraction distance. At the lower levels (1mm - 6mm) it is slightly smaller in length than at the higher levels (7mm - 12mm) but it remains no matter what.

 

I'm only about 1 1/2 months into the hobby and have tried googling/YouTubing the issue but to no solution. I'm hoping that perhaps someone here may be able to point me to the right direction as to what setting I should be adjusting now to remove the extrusions from both sides.

 

Thank you.
