If there is excess filament coming out of the hot end, follow the steps below.
1. Reduce the extrusion percentage on the Printer Control Screen or Web Interface.
Note: Filament diameters can occasionally be over diameter.
First Layer Not Sticking to Bed
If the first layer is not sticking to the print bed, confirm the following items:
✓ The bed temperature is at the correct temperature.
o
If not, wait until the temperature is met.
Note: The bed can be preheated to the print temperature to allow for extra time for
heat to transfer from the heater to the build plate.
✓ An approved material is being used.
✓
The end of the nozzle is clean of excess material.
✓ The nozzle is properly gapped to 0.2 mm.
✓
The bed is level.
o
This can be done by quickly checking the four corners with the Check Bed
Level macro or run Quick Level macro.
✓ The filament is dry.
o
Consult the manufacturer for the appropriate drying procedure.

o
The bed can be cleaned with isopropyl alcohol
TIP: Lightly rough the bed surface with 200 grit sandpaper if necessary.
