I think I finally know how to 3D print in PLA. Got the OBJ file from Thingiverse (Ice Dragon - thingiverse.com/thing:45658), sliced it in Cura and 14 1/2 Hours later I had this... It's about 120 x 120 x 120mm. Biggest volume I've ever tried and longest print time so far.
I finally got my BLTouch dialed in and from initial to final layer, my TT never blinked. No wobble, no blobs, no shifts or glitches. Hatchbox PLA, 200/60°, 0.2 layers, 60mm/sec, 3 shells, 20% infill, 800 Accel, 8 Jerk, 6.5 retraction. W/ Supports.
Ran it through IdeaMaker and it wanted 32 Hours to print. Needless to say, I used Cura. That's a US Nickel in the photo for scale.
