what is the real print speed?

Hi

I'm getting confused about the real time printspeed. Hopefully, anyone could explain this to me.

Cura says standard print speed of the ultimaker 2 is 50 mm/s. I think that is quite fast. In the yellow pop-up window it says: 'You print 2.0mm^3 per sec which mean 8 sec/mm.

What does 50 mean?

50 mm/s is the max speed of the head. The other one is the cubic mm of fillament extruded.

50mm/s is only the max speed in this one example. In reality it can go faster.

2 cubic mm of filament per second is reasonable. The machines are tested at 8 cubic mm before shipping (that's too fast for a .4mm nozzle in my opinion - they push it to the limit).

I expect you are still not clear on this but you need to ask more questions if you don't understand yet.

By the way - to calculate the volume you multiple LXWXH or print speed X nozzle width X layer height.

So 50mm/sec is no problem at .1mm layer height like you chose but if you go to .2mm layer height now you are at about the limit that I like to print at (4 cubic mm/sec).
