First layer narrower that rest!

[jateu01 2]

Hi All,

 

Really odd issue happening. I'm using cura to slice. The problem is that the vertical side(red) is narrower than to when this item has a straight square side. I've used the green line to represent the build surface or part. As you can see with STL this part it's vertical not curved or chamfered etc. 

 

As I am using ASA the initial layer speed is very slow to get adhesion and z axis is lowered slightly on printer manually. 

 

Bed temp 100°

Filament temp 240°

Initial print speed 5-10 

Other layers print speed 30

Retraction 2mm/35mms

No cooling 

In a cabinet to keep warm 

 

Can't think of any other info. But this is weird 

 

Many thanks
