First Layer Issues
First layer is printing great but then after a while it starts to look bad. Anyone have any ideas on whats going on or any recommendations? I checked the nozzle and it was clean with no PLA blobbed on it. PIC attached!!

dirty bed?
try a soap and water wash
plain dish soap ( dawn/fairy) and clean paper towels
RE: First Layer Issues
Layer 1 or Live-Z is off; looks too high. The bed also looks very uneven front to back - like there is an assembly problem or the mesh level is not working or the bed calibration offsets are wrong.
Your bed is incredibly dirty; it really needs a soap and water wash at a sink, with gallons of hot water rinse.
And that extruder fan grill is causing you problems. It limits X-axis range and interferes with homing and calibration, not to mentions reduces airflow in the one place it is essential to maintain the best you can get.
