3. HETABED CALIBRATION
Recommended frequency:
- each time after the device has been relocated,
- in case of poor adhesion of the first print layer to the heatbed or an unevenly laid first layer,
- in the event of a collision between the hotend and the model.
The 3DGence INDUSTRY F340 printer features an advanced, ultra-sensitive automatic heatbed calibration system
for easy operation. The following describes the procedure to follow to calibrate the printer heatbed correctly. The
printer is calibrated prior to shipment, but during transport it may have been misaligned. Therefore, it is
recommended that you perform the following actions to avoid print problems. The calibration procedure of the
work platform is the same each time. There is no need to carry out calibration before each printing, just once
every several dozen hours of printing or whenever problems with the adhesion of the first layer of the print arise.
Heatbed calibration procedure:
1. Remove dirt and residue material from the nozzles using the hotend cleaning procedure described above
(Section 1) and from the heatbed (Section 2). The heatbed and hotends must be clean before calibration.
2. Make sure that the temperature of the hotends is below 50°C. When the hotends are heated, set the
temperature below 50°C using the +/- buttons: Menu → Tune → Temperatures.
3. Home all printer axes with the option: Menu → Prepare → Home All.
NOTE: Observe the movement of all axes carefully. When the Z axis reaches the end position sensor (Fig. 1) and
stops, use a feeler gage to check the distance between the nozzle and the heatbed. It should be approx. 0.8 to 1.5
mm. A longer distance can lead to interruption of heatbed scanning and an error will be displayed. If the distance
is greater than 1.5 mm, adjust the distance manually. To do this, loosen the adjustment screw (Fig. 1) and adjust
the distance manually. Raising the Z axis cutter (Fig. 1) will increase the distance between the nozzle and the
heatbed, lowering it brings the nozzle closer to the heatbed. Once set, slightly tighten the adjustment screw
(fig.1) and check the nozzle position using a feeler gauge, after selecting the "Home Z" command, available
from the Manual Controls menu.
4. Calibrate the heatbed using Menu → Calibration → Heatbed scan. Calibration will take approx. 90 minutes
