Hi,
I just joined this forum, and I'm new to 3D printing. I have been using Comgrow PLA White and Black filament without getting a good print. The raft or brims print fine, and the first layer looks OK. Then, the following verticle layers are attached at the corners but detached from the Infill in between. A calibration cube or box has a good core, but I can peel off the outer layer.
Any advice would be appreciated.

I am also a new user. I got the Ender 3 Pro for Christmas along with two rolls of Comgrow PLA, one black and one white. After assembling, leveling, and calibrating the Ender 3 Pro, I ran a few small items using the sample roll with no problems. When I switched to the Comgrow, everything turned to garbage. I have repeatedly run tests at different tests and finally got what at first looked like a good calibration cube. When I looked closer, I found the side layers of the cube were delaminating. Everything I have tried has failed to stop the delamination of the skin layers.
I'm looking for any hints or guidance.
Thanks in Advance for your assistance.
