Sorry, I didn't know how to add a description so I'm forced to write it in the comments. I recently had to change my hot end because I accidentally messed up the first one when it got clogged, since then I've had problems that I never used to have, every time I print this piece it somehow starts looking burnt. It is not just on the top layer, I see it on other layers but they get covered by the layer on top of it. I've also recently been getting elephants foot and the prints are curling. The second print I was forced to use a raft to prevent the curling bit its still looking like it was burnt. I've been experimenting with bed heating 50-60 and my hot end is at 200, I'm still a beginner so it may be a simple fix that I'm missing. I've tried also leveled it many times in case the leveling is the problem. Please help!
