6.8 Checklist
If you followed the steps described in the previous chapter, you are now ready to start your first print.
Before you start, let’s go through the final checklist:
1.
MINI is fully assembled and placed in a suitable location
2.
The firmware is updated to the latest version
3.
All of the calibration procedures were successful
4.
A clean print sheet cleaned with IPA-infused cleaning wipe is on the heatbed
5.
Filament is loaded
6.9 Starting the first print
Once everything is ready, you can
navigate to the PRINT menu
(available only when a USB drive
is inserted). Use the knob to
select a sample object
from the list and observe the printer. We
recommend choosing the
PRUSA logo,
because it gives you a great overview of how well you
tweaked the first layer during First Layer Calibration.
You should aim for this level of quality with your first layer
