Hi Rob

What material are you trying to print with?

If its ABS or PETG then that will need higher temps than say PLA and also an enclosure is preferable (especially with the colder weather we have atm). If its PLA then that's something different and might be an extrusion speed issue (your photos suggest it maybe over extruding, but hard to tell without video and the glassy surface looks like you're acetone smoothing after printing?).

Another issue that is prevalent in the winter weather is cold and damp filament (most are hygroscopic) and whilst I also need a desiccating oven/heater, I have had some filament "come to life" just by sticking the reel on a radiator for an hour before printing with it.

Hope that helps, but post more on printing and Fusion if you need more.
