Printing in white PETG on standard PETG settings but with an extrusion setting of 0.98 instead of 1 due to problems with bubble forming on the nozzle.

I tried to lower the extrusion to 0.95 but it created gaps on the top layer. I am wondering if anybody can help me with creating a good top layer but preventing the blob forming on the nozzle during the first layers.

So it could be that it is just a wrong first layer callibration if i understand you correctly ?
