Slicing direction?

[Zlutz 0]

Slicer works this way:

First it prints "1" north-east to south-west

Then it doesn't move the print head north for "2", it simply slices it the other way around (south-west to north-east)

Then it hast to jump over the printed stuff, and prints the "3" north-east to south-west

 

I  would like it to print in the same order (1, 2, 3), but I would like it to print it always north-east to south-west.

 

Is there a setting I can change to make it so?

 

Photo attached - all I want it to do is print "2" in the same direction as "1" and "3"

Could you please provide the .3mf file for your project so we can play with it ourselves and see what we can make happen?

 

Also, I am sort of curious why this behaviour is an issue - does it not print as well or something?

I'm printing a thin thing and it needs to be as smooth as possible while being completely filled up (no holes)

I'm using 102% extrusion for that purpose so there's a bit of extra material being "pushed".

 

When the second step goes in the "wrong direction", fresh pushed material meets old pushed material from the first step, and I get too much material at that point

 

Then the third step starts printing and it's perfect at continuation of first step, and looks a bit different at the continuation of the second step...

 

Also, when you look at the final print, you can see a different pattern at step 2 because it's printed in the other direction.

 

I made a quick STL if you want to play with it. It behaves exactly the same.

A Cura project file (.3mf, in Cura go to File > Save Project) would be better, that will include your slicing settings and such.

Here it is! 🙂

Go to Top / Bottom and turn on Monotonic Top/Bottom Order

Well thank you very much, my bovine friend! This is EXACTLY what I was looking for.

I would never think to search for "monotonic" or think it has anything to do with "top/bottom" options... 😄

The funny thing is, this part would take 1:18 to print with and without this option so it doesn't cost anything!

Always happy to lift someone's MOOd (sorry, I have to milk all I can out of the cow puns). I can understand why 99% of people would look at the title and go straight past it, but I have too much free time so I can try these things to see what happens 🙂
