BFB 3000 Operations manual

Calibrate the Z height

A nozzle that is too low by just a small amount to low will give a fatter raft

filament. If the nozzle is more than 0.2mm below ideal height it can

damage the print bed and cause the extruder to skip on the filament. You

can clearly see the melted acrylic around the sides of the very narrow

filament bead, this will not be able to be removed from the print bed and

has to be lightly sanded to give a smooth finish to allow further printing to

take place.

ADJUST THE Z HEIGHT TO CORRECT IN SMALL STEPS AS SHOWN

IN (Fig.1)

Re-print the test raft file to check the new z height
