upside-down print, bottom layer is top

[mzagrabe 1]

Hello,

 

Cura 4.8.

 

I'm making a print that needs to be upside-down. I'd like the bottom layer (really the top of the print) to have the same smooth finish that a normal print would have on the top.

 

I've looked at the settings and don't really know what to adjust to get a "nicer" layer on the bottom.

 

Any ideas?

 

Thanks!

This is kind of an odd request as generally the bottoms look pretty good and it's the top that can be an issue.

 

If you move up to Cura 4.12.1 or 4.13.1 then "Monotonic Top/Bottom Order" insures that all the lines are moving in the same direction...no more of half the lines while moving to the right and the other half while moving to the left.

You can try pushing the "Initial Layer Flow" to 105% or so to insure all the lines get welded together.  If it's PLA then keeping the speed down to 25-35 can help as well.

 

Maybe someone else will come up with a better suggestion.
