HELP - First Row Not Printing Properly

[curious aardvark]

yep - bed levelling is pretty much the most important thing to gettign a printer working.

for the record if you are missing lines on the first layer it's because the printhead is Too Close to the bed.

The other thing to remember is to remove filament and heat the nozzle when bed levelling.

Thanks for the reply.

After sorting out the bed levelling I went back to PLA and it prints great all the time. Must be that the levelling is not so critical compared to PETG. With PETG I need to make minor adjustments to the bed after starting to print the skirts. It is just not like PLA which seems to print good all the time on the first row.

I guess that is normal.
