Got my ultimaker a month ago and since day one I wished for a better support algorithm, super happy that it's happening
I did some testing with T2 and here is what I found :
- with attached STL (scale 5.0) it decided to print mid air (screen #3)
- with Distance Z at 0.6 it started building support structure past the point where it was needed. Look at the arc section (screen #4). I expected more separation, but instead it sees like Cura extended support material in Z direction by that amount. There are 3 layers past arc. Layer height was set to 0.2mm , so it makes sense 0.2 * 3 = 0.6mm but im not sure it should be happening. I thought support material should have been pushed down .
And some pics of the print
after I cut through raft
Had to use some considerable force and pliers to separate the bottom part
I couldn't get rid of support material inside the arc because it expanded past actual mesh
Also I couln't agree more with Matt about having both parameters for support - spacing and flow rate.
EDIT: forgot to link to an STL in case it's needed
