I am printing at 35mm/s most of the time. My problem is when I am jumping from one tentacle to the other, my retraction is not good enough to prevent some plastic to spill from the nozzle during the travel time. This leads to crapy results in good case and print faillure in bad case. (And if I try to retract more wire or faster, I damage the wire etc., I did not find the good balance yet).
I have done (and commented with a picture) on your Death Kiss also.
I love your work dude, I don't make comments on everything I've done from your gallery, it would take too much time ;) -mostly because this website is a mess when it comes to find one particular model among your 18 pages...
