I just got a creality k1 max and it did its first few prints fine but when trying to print out a death whistle the first print came out with gaps like this: https://imgur.com/a/RCy1qCV
So I read on here that it could be caused by underextruion due to heat creep with PLA and that can be remedied by opening the top, after I opened the top and tried again it started printing out like this… https://imgur.com/a/2XGXp2D so I stopped it. I am very novice at this and I dont want to go making assumptions and mess things up. What are my first steps of diagnosis?
