Hi,
I'm very new to 3D printing, still trying to learn the terminology and figuring out things. I recently bought a Creality K1 Max, I was able to print a few models no problem, but my last few attempts to print have all had the same issues. It looks like the printed layers start to curl, almost like if they were being burnt, so they curl and create a big mess, so I've had to cancel the printing. I thought it was the nozzle temperature, and reduced it from 220c to 200c, the bed temperature is at 50c.

I don't know what to look for, any tips are welcome.

I'm using PLA+ black.

Thanks
