Comment on (UPDATE: I think I found the solution?) Unable to print larger 3D models?

I have edited the post with a large first layer print. There are many imperfections, what does it mean?

How old is your printer. ?
I had near 2000 print hours and started having first layer problems. I did a lot of troubleshooting and nothing worked.
Ended up being that the heat block needed replaced. Even though it seemed to be functioning. It was causing flow errors or something.
It could also be that the screws around it get loose. That’s actually been most people’s issue but that wasn’t mine.
I replaced the heat block and it fixed it. Here is a link to the thing I’m talking about. Explains to check screws first before considering replacing the heat block.
Hopefully that’s your issue cause that’s easier to do than replacing the heat block.
A poor first layer may not be super noticeable at first. But the problem for me was it got worse over time and did result in prints lifting.

My printer has 676 hours. I will try looking for the screws of the heat block and see if any are loose!

Be sure to check the screws on the backside. You will need to take out the front three to access it.
