Figure 6. 6 Material calibration interface
Steps to calibrate the weight of materials in left and right bin are as below:
1. Click the blue "Wl" / "Wr" icon in Print interface to pop up a dialog box, and take off the material
and spooler of left and right bin, and leave only the left and right material roll on the weight sensor;
2. Click "OK" button to complete the calibration;
3. Click “System” interface, input the weight of empty spoolers in the “L-Spooler” and “R-Spooler”
input box respectively. The printer will automatically calculate the actual weight of left and right
material, where the values are displayed at the "Wl" / "Wr" item in Print interface.
6.4 Calibration of the Clamp Force of Extruder
During the printing, the filament threads between the movable drive gear and the fixed driven gear, of
which the driven gear can be moved to the left side or right side according to the directive from the printer,
and there are spaces on the left and right for the limit switch to control the motion of driven gear.
The clamping value of left and right nozzle can be set at the item of “L-Clamper”and “R-Clamper”in the
“System” interface, where the clamping value denotes the distance in mm of the forward movement of
drive gear after triggering the position switch. The clamping value directly affects the smoothness of
filament feeding. Generally, the greater the clamping value is, the smaller the distance between drive gear
and driven gear will be. However, the clamping value shall be set in a suitable range. An excessively small
clamping value will cause the under-extrusion of material; an excessively large clamping value will cause
the drive gear bounced by the filament, and the distance between drive gear and driven gear will
increases instead, also causing a under-extrusion of material.
To calibrate the clamping value, use the steel bar with 1.3mm of diameter in the accessory box as the
calibration benchmark. and operate the calibration of clamping value according to the instructions on
screen. Taking the calibration of “L-Clamper”as example, the steps are as below:
1. Retract the filament in left nozzle. (Click the “Material” button to enter the material interface; click
“Set Temp(℃)” button, and wait for nozzle heating; when the temperature reaches the set value,
the material in nozzle has been melted, long press "E↑" for over 3s to retract the material out of
the nozzle range; finally disable the nozzle heating);
2. Press the quick snap joint and meanwhile pull out the feeding pipe;
