BFB 3000 Operations manual

Calibrate the Z height

Printing the test raft allows us to asses quickly the accuracy of the Z height setting in all four corners and in the middle of

the machine, the G code file is set to operate with a 0.5mmØ nozzle and BFB ABS filament (as per the test sample).

Rafts are used when printing to give good consistent base layer, this removes any irregularities in the printing bed and

makes it easier to remove the printed part.

step

The 8mm print bed needs to have the surface shine removed, this is best done with some 240

grit sand paper to rough the surface.

step

The test raft is too sparse for use as a normal raft but is used to check Z height & that the bed is

level. Go to our web site and copy the file “TR3000.bfb” onto the SD card, load the SD card into

the controller and select the file from the “RUN FILE” menu. Your BFB 3000 will, home the tool

head first, warm the extruders and then start printing a raft in each corner of the print bed and

one in the middle.

All five rafts should look the same and have the same filament

width this should be 1.9mm – 2.1mm.
