Most important things:
1) 100% fan by the time it gets to the overhang - there is probably zero fan on the first 2 layers.
2) not too hot. 220C should be okay but 210C better. 200C even better but then you have to print more slowly or it will underextrude.
go into Cura with your robot and set the layer to .1 layer height.
then drop the print temp down a bit to maybe 200ish.
print speed 50 should be fine...and have the fan cooling on 100%
good luck !!
PS... the robot model is actually not so so good for printing !! i know it is the company symbol for ultimaker but the model itself for printing is not the best.. so dont shoot yourself about this robot and printing it perfect... I never got the damn little guy perfect and Im printing big detailed prints all the time... and all super :smile:
