Printing over support structure issues

Hi there,

First post so I’ll quickly introduce myself!

My names luke and I’m an ICT service engineer based in lincs, I have only owned a printer for about a week after building it! So very new to it all

when I print over support structures I never seem to get a solid fill on the first few layers

I’m using the cura engine as I haven’t worked slic3r out yet and don’t know any optimal settings

Printing with PLA

Any advice will be great fully received
