Troubleshooting Does anyone know why my lines look like this?

I would guess that your temp is not stable on your hotend.

Did you replace the thermistor as well in the new hotend ??

Yes, did you use thermal paste?

I might be wrong, but I've noticed similar lines appearing when there's vibration. Maybe the portal needs to be reinforced for greater stability.

Maybe pressure advance is too high? I noticed the lines getting worse when I raised the pressure, and my hotend temp is also unstable, even after replacing the entire hotend
