So, what material, temps, speeds etc. What is the glassed prep'd with?
When I get what looks like minimal extrusion and the material gathering on the nozzle rather than sticking it is usually the surface prep is not good, gap between the nozzle and the bed is to small.
I find that on two of my machines that the right nozzle tends to be lower than the left once installed in the machine so i shim the whole assembly. So check again the level on the right nozzle and the gap.
