Chapter 4: Preparation before printing and common faults
The machine has been checked and tested and adjusted well before
shipping, but there maybe some little error due the vibration during the
delivery. Normally, we would send the printed samples together with the
machine, so you can take down the samples and directly start printing.
Preparation before printing
1. We should do the leveling work for first time use, left alone for long time or
after moving it. It does not just mean the leveling of heating board, but also
need to adjust the distance between control plate and the extruder within a
reasonable range, which normally for a thickness of an A4 paper. This leveling
operation would directly affect the performance of the first printing layer, then
may affect the whole quality of the printed item, since it is piled up based on
the first layer, forming a uniform model. So please make sure it is leveling
before working.
In the printer cabinets, there is a dismountable plate with tape, and it is the
printing platform. The tape would make it easier for us to separate the printed
sample with the plate. We can tear down the platform and replace the tape
when it is broken after long time use. And it is very easy to tear down the
platform, we just need to loose the 4 springs.
Generally, we can skip the rough adjustment and directly do the fine
adjustment. But it would be better to make the rough adjustment if the machine
has not been used for long time.
Attention: The leveling operation is very important, please make sure it is well
leveled before printing. Normally, the machine has been strictly checked and
tested before reaching customers. But it would lose balance due to the
uncertain factor and misoperation in the transportation. So it would be better if
you can adjust and confirm it again, we can operate like following manual.
Open software ，press “3 axis homing” (as this picture), then XYZ
axis would be back to original, ie. Reference point.
