PETG mess, from blobbing to total destruction

Hi all,

I have exhausted my options with this gold PETG. I accept the fact that the filament isn’t great but the other colours print well. I have played with temperature, speed, retraction, flow rate, and dried it too.

Yet, it starts ok but then the nozzle seems to collect material from the surface as it prints and eventually it starts to take pieces of the surface and the whole things becomes a mess. I don’t know if the blobbing is what starts dragging around and lifting the layers or if it’s something else but some geometries seem to work ok and others don’t work at all.

Any suggestions on what to do would be greatly appreciated. I have been printing slowly, starting with 30mm/s and it still isn’t working.

Thanks
