I’ve been trying to print this: https://www.thingiverse.com/search?q…&sort=relevant. One of the pieces in particular will not print properly if its brought into Cura and laid flat.
It’s the actual phone clamp that goes on the end of the arm. When imported into Cura it’s standing up on end, which I think is nuts, so I laid it down flat by rotating 90 degrees. I was careful to ensure Snap Rotation was checked and that the rotation was exactly 90 degrees.
Still, when I tried to print it, 1 half adhered to the bed just fine; the other didn’t. I tried various temp & speed settings, but nothing worked. Then I remembered the issue I’d had printing the support arms for my Ender 5’s printbed. So I checked and, sure enough, when viewed up really, really closely, I could see daylight between the bottom of the phone clamp and the printbed. Arrrrgh!!. Instead of trying to rotate the clamp so it fully contacts the bed, which I’m pretty sure isn’t possible, because I don’t think the model is completely flat, I instead sunk the model into the printbed by 0.2mm. I did this by using the move feature of Cura and changing the Z distance by -0.2mm. That worked.
Now, the only issue remaining is the warping. This filaments.ca EcoTough filament seems to warp on really narrow parts, but it’s such a unique filament I feel it’s worth importing. Most likely, if I used a brim, it would be OK. The issue I have with that is Cura doesn’t seem to offer the ability to use brims selectively on 1 model on the printbed, but not others. If someone knows how, please enlighten me.
