I've got an odd defect in my prints that I'm trying to chase down. I have a small box with some printing on the bottom (2 layers deep), and I've tuned up the retraction & restart distance to give good results on the letters Those settings weren't quite the best to minimize the groove where things start & stop for the side walls, so I set up a separate process to start on the 3rd layer to keep things tidy.
This was working OK with black eSun PLA+ filament, but I ran out of black & switched to green. That seemed to be very liquid at the same temperatures, so I back off on that, and re-tuned things a bit. The bottom of the box has a small 45 degree bevel on the edge, and I am getting large blobs where the perimeter starts, but as best I can tell, it's not on the first layer. It's acting like it's not retracting when it moves to start the 2nd layer.
I thought it might actually be from the process change when I switch at the 3rd layer, but I printed the example below with a single process, and it's actually worse. It appears to be blobbing on both the 2nd & 3rd layers, and sagging down onto the built platform.
I'm guessing that it's something I changed in the retractions settings on the Advanced page. I've been chasing this for a couple days, and my brain is fried. I've attached my factory file in case somebody has more functioning brain cells than I can muster at the moment.
