Hello everyone, this is my first inquiry here so firstly thank you for any help you can provide. Secondly Im having issues with my Ender 3 Pro. Like most people my bed isn't perfectly level and because I'm using the magnetic bed those dips can cause some mild leveling issues. Once I get everything level though and start printing everything seems fine. A few hours into my prints though I start to get gaps in my lines for both the infill and my walls. I thought maybe my bed adjustment knobs were backing off. So I lightly raise the bed in the area im noticing it happening and the lines will go away but eventually will form again. Then I thought maybe it was pillowing but further research showed it didn't look anything like pillowing. So then I thought maybe I needed to increase my flow from 95% to 100% which helped slightly but the gaps are still there.
I know ironing can help, but this is happening on most every layer below the final layer, meaning those gaps in my walls go very far down into my print and I would rather fix the problem and not just the visible layer. My friend recommended trying to decrease the line distance, currently it's set to 1.6mm, to try and ensure they stick together. I was thinking perhaps a glass bed to replace the magnetic one help since it would actually be flat compared to my bed. What do you all think? Included is a few images of prints with the gaping im taking about. Again thank you all and happy printing!
