First, let me give a huge thanks out to the programmers for improving the supports in Cura 3.0.
I am trying to print the attached part (it's from the universal construction kit, it is a Lincoln Log with a k'nex piece sticking out the side).
I have oriented it laying on the side so the layers will go down the length of the k'nex part to make it stronger and hopefully prevent breakage along the layers.
The problem is the support structure is sticking to the part. In previous versions of Cura, I could pull the supports off with my fingers, in 3.0 it is taking an Exacto knife and a jackhammer.
I'm running a 0.35 nozzle with a 0.2 layer height and I have increased the Z support distance to 0.35 and the XY to 0.7mm and its still sticking. Today I printed this part multiple times incrementing the Z support height from 0.1 all the way to 0.35 in 0.05mm increments. All of the supports stuck.
I'm running Cura 3.0.4 if ti matters
Thanks for any assistance.
