7.2.10 Print speed versus print quality
Printing a small object takes a few minutes, but printing larger models is more time
consuming - there are prints taking up to tens of hours. The overall printing time can be
changed in different ways. The first way to alter the printing speed is by changing layer
height in PrusaControl or Slic3r - the upper right window shows Print settings option. The
default setting is 0.15 mm (OPTIMAL), but you can speed up the printer by choosing the 0.2
mm (FAST) option. Raising the speed will result in the model being less detailed with visible
layer borders. If you prefer quality over speed, choose 0.10 mm (DETAIL) or 0.05 (ULTRA
DETAIL) option. The ULTRA DETAIL option is available only for PLA. Printing time will
double but the model gets the extra detail. Again, a higher printing speed results in a
less-detailed model.

Pict. 20 - Print quality vs print time
The speed can also be changed while printing. The LCD shows the FR 100 % item - it’s
actual print speed (feed rate). By turning the LCD-knob clockwise you can increase the print
speed up to 999 %. However, we do not advise increasing the speed over 200 %. Watch the
results of increased speed on the printed model and adjust the speed accordingly.
When increasing the speed always check that the model is cooled properly -
especially when printing a small object from ABS, increased speed causes distortion
(sometimes called “warping”) of the model. You can prevent this issue by printing
more similar objects together - layer printing interval is long enough to prevent this
issue.
If the model shows a lower quality than desired, you can decrease the printing speed - turn
the LCD-knob counterclockwise. Minimum usable printing speed is around 20 % of the
nominal speed.
7.2.11 USB cable and Pronterface
We strongly recommend using the LCD panel while printing on the Prusa i3 MK2.5 -
Pronterface doesn’t support all functions of the new firmware (e.g. filament change
while printing).
