Cura2.1.2 - Why are my Rafts so crappy?

DaHai8 · June 10, 2016

I must have a setting wrong in Cura2.1.2

With Cura 15.x, my rafts are smooth and flexible and they peel off the object in one piece with acceptable effort.

But with Cura 2.x (using Cura 2.1.2 now). They are full of holes and come off the object in little pieces that I have to pry off with pliers or file off. It's a mess and leaves a even more messy finish behind.

I've tried to match the Raft setting between Cura 15 and Cura 2, but I'm having trouble matching up the dissimilar verbiage.

Here's Cura 15 Raft settings:

And here's Cura 2 Raft settings:

Any help, ideas, suggestions are greatly appreciated!

BTW: I know I post a lot of questions, issues here on Cura. Don't misunderstand. I think Cura 2.x is AWESOME! And am using it exclusively for all my slicing. I'm gonna win myself an Ultimaker in the Thingiverse Challenge!

I'm just surprised that people actually use raft.

I have the problem of either not being able to get the object off the build-plate, or having it come off mid-print. A raft gives me a good happy-medium since there is limited material touching the build plate. Plus, with objects will small contact areas, I find Rafts work best. And being the edge are flexible, its easier to get something underneath an edge to pry it up.

Brims don't seem to do much for keeping sharp tips from curling up as well.

Still Cura 15 rafts are smooth and remove from the object cleanly. Cura 2 rafts come out full of holes and take forever to pry off bit by bit.

Gotta be a setting I'm got wrong somewhere...

Alrighty. After half-a-dozen tests, I've found the settings that work most like Cura15 - at least for me. If anyone has similar Raft issues and still uses Rafts (sorry, Labern, you're not in this Venn Diagram ), perhaps they'll find this information useful.
