Warping, Ultimaker 2

[Bikeracer2020]

I'm only printing with ASA at the moment, some things that have helped me to minimise warping that I've found so far....

Enclosed printer
Preheat the bed and then wait 20-30 minutes before starting a print to get inside the enclosure warm.
Nozzle temp 255.
Bed 94
Speed 25-30 mm......lower better
On no account open the enclosure until everything has cooled right down to ambient, ideally print finishes at bed time and is taken off the bed next morning.

Magigoo on the bed and if any sticking problems when cold just dribble some water round the edge and wait a short while for it to soften the Magigoo.

I'm not using a raft and just a skirt to purge the nozzle first.

Pics of print, 128mm long, 70mm wide, 100mm high.
Print came unstuck off the bed with no effort, just lifted straight off, no warping but I do need to start and tackle setting the retraction in the slicer.
