2.When the temperature reaches the target temperature, click “homing”, choose to
homing, so that the axes are back to home point.(Attention:Model printing failure to
select Breakpoints recovery the operation between the Midway, if there is a power
outage must be homing operation, such as continuous electricity can not return to
home point operation).as Figure 2

5.After you select the file, wait for it to print.as Figure 7.
(After selecting the model, the larger the model, the more complex it is, the longer it
waits here.)
The steps of breakpoints recovery:
1 2 3
7 6 5 4
5.6 Save the gcode data with power off
In the printing process into a paused state,when without anyone watching you can
directly shut down, the next time you can start from the pause to continue printing.

(Attention:Remember to delete the updated file in the SD card, to avoid the reboot
and update the firmware, affect this feature).
5.7 Power off recovery
1. No UPS Power
1.1 A sudden power outage during the printing process, machine can continue to
print from the power off. (due to power failure can not drive the motor, the print
head will still remain on the model, may cause defects in the model, if the need for
more complete power off processing, the need for power detection module and
UPS).
2. Have UPS power
2.1 Power detecting module signal line s connection PB0, negative positive
connection -and + two pins blow the PBO.
2.2 When the system loses power, the Power detection module informs the touch
screen to enter the suspend printing state, UPS power supply. Leave the print head
out of the model.
