This is a side note, but your prints look just like mine at first. The PLA that shipped with the device was terrible! The white was good but the black… I had to throw away because layers did not adhere no matter what height or nozzle temp.
Curious, I’ve printed with both the white and black and haven’t noticed much difference between the two at least as far printing my D&D mini’s have gone. I printed some CNC clamps with the white PLA that came out really well and I’ve printed about a half-dozen reference cubes with the black PLA that were fine (once I got the print settings straight anyway).
