Why does the um2 slow for the last layers?

Just curious but, why does the printer slow for the last few layers, i was just thinking about it and couldn't think of a reason, so i thought id ask, its just that ive started to print a few small things and it melts the hell out of them unless i guess print stuff alongside them to stop the nozzle staying in the same place too long? Im not even sure its cooling down the temp to compensate, is there a way to disable this 'feature'?

Probably it's your cool head setting http://support.3dverkstan.se/article/30-getting-better-prints#enable-cool-head-lift

Its the minimum layer time. the minimum layer time slows the print speed if it would normally take less time to print that layer.

It can be a hard thing to correct. you can use cool head lift, print a small tower next to the print to allow for more cooling or print 2 items at the same time.

Ill just print a few at a time. Its only small. Thanks for the reply, i thought maybe you could just disable it somehow.

you can adjust the time and make it so it wont take effect, but it can (and probable will) end up to hot. as it will end up putting hot plastic down 2 soon on the previous layer which is already hot as it hasn't had time to cool.
