FAQ
Question1: How to update the firmware?
Question 2:What if the filament does not discharge from the
machine?
1. Copy these two files to the SD card
2. Then restart the machine and wait for
the machine progress bar to complete
before the firmware is refreshed.
3. Then the user needs to delete the two
files in the SD card to be used normally,
otherwise the firmware will be refreshed
every time the phone is turned on
1. After the machine nozzle is heated, the
consumables are normally fed into the
feeding mechanism by hand, and then
passed through the Teflon tube to enter the
nozzle.
2. When it is found that the gear of the
feeding mechanism emits a "beep" sound, it
can first check whether the consumables
are
wound, causing the extrusion
mechanism to pull the material.
3 If this is not the reason, raise the machine
nozzle and use the 0.4mm needle in the
toolbox to insert it from below the copper
nozzle and rotate while inserting.
4. Under normal circumstances, this needle
can be used to open the copper nozzle, so
that the feed is smooth. The reason for this
blocking is generally that there are
impurities in the consumables, which leads
to plugging.
