Calibration Of Offset Between Hotends In The Module In The X, Y, Z Axes - 3DGence INDUSTRY F340 Maintenance Manual

5. CALIBRATION OF OFFSET BETWEEN HOTENDS IN THE MODULE IN THE X, Y, Z AXES

Recommended frequency:
- each time after installing the module,
- each time after the device has been relocated,
- in the case of poor adhesion at the contact between two materials,
- in the event of a collision between the hotend and the model.
Z offset calibration:
The Z offset between the T0 hotend and the T1 hotend is a key parameter for high print quality. A correctly
calibrated Z offset value allows you to obtain high quality surfaces between the raft and the base material and
between the support and the base material.
The 3DGence INDUSTRY F340 printer enables automatic offset measurement in the Z axis. The measurement is
carried out with the use of a strain gauge and consists in determining the difference between the height of the T0
and T1 hotends.
In order to carry out the measurement select: Menu → Calibration → Printing Module → Measure T1 offset.
Calibrating X,Y axes offsets:
To verify the offset in both axes, print the calibration model stored in the printer's memory (the procedure is
described below). The model consists of two parts - part X (Fig. 5) and part Y (Fig. 6). Part X is used to set the
offsets between the hotends in the X axis. Part Y is used to set the offsets between the hotends in the Y axis. Each
part consists of two layers of material - the bottom layer printed with the supporting material (Fig. 5, white) and
the top layer printed from the model material (Fig. 5, red). Each part of the model is built with 11 lines. The
middle line is the 0.00 point. The lines to the right of the 0.00 point increment with the plus sign every 0.05mm
within the range from 0.05mm to 0.25mm, and lines to the left from point 0.00 decrement with the minus sign
every 0.05mm within the range from -0.05mm to -0.25mm (Fig. 5, 6). The printed symbols: "+" on the right and "-
" on the left are helpful in determining the sign with which the read value must be entered into the printer (Fig. 5,
6). With correctly calibrated offsets on the centre line (point 0.00), the model material matches the support
material both in the X axis and in the Y axis.
