BFB 3000 Operations manual

To get a good print the bed must be level to within +/-0.1mm (0.0004”). The print bed is mounted on 3 levelling springs this is to

allow micro adjustment of the print bed without having to adjust the main Z pulleys.

Before making any adjustments: ensure that the rear two adjustment bolts (shown below) are sufficiently screwed all the way

into the metal bed corner. Feel that the ends of these two adjuster bolts protrude flush with the underside of the metal bed

corner. Then screw the front adjuster bolt down to compensate, making the bed approximately flat.

step

• With the extruder fitted move the tool head to the rear left corner (Fig.1)

just over the print bed.

• Move the print bed up using the “Z+” button in “MANUAL MOVE” until

the scraper just slides under the nozzle (Fig.2) with very slight resistance,

Make sure it is not compressing the levelling springs.
