Hi guys .. today we try a new printer from gearbest
we see how it works .. enjoy the video
the mechanics
is a type CoreXY
you have a aluminium cube
the lateral brackets are double
the bracket is type V (2020)
the wheels are good
the carts comes already assembled
but .. it may not be well assembled
I found 3 wheels
that have ballbearings
assembled wrong
I needed to disassemble the wheels .. rotate up/down the ballbearing .. and after go well
obviously one of the 3 wheels was this .. on back of extruder
I had to disassemble all to correct this wheel
then
the plastics components are
these plates
the carts plates
and the motors plates
that is a bit thin
I suggest to add a cable strip like this
and you never have problems
there is a cable chain
for exstruder and the bed
the bed is 330x330 mm
the plate over is in fibers glass
and is not planar
I suggest to find a glass plate
no special glass
simple 3mm glass ... works well
I already use that from 3 years on my 3drag
and it never broke
the support of motors of z axis is made with plastic
but in this case I not see problems
it only block the movement ... of the steal rods
all pieces of bed
this .. this .. are in aluminium
all pieces .. these rods
comes very straight
nothing problem
pieces of bed
all in aluminium
this is 1cm of solid aluminium
very straight
same this .. aluminium .. 5mm of thickness
and these ..
the rods
very straight
same these
cleaned .. no smudging
the extruder is a MK10
there is this fan to cooling the pieces
works pretty well .. but
should be on both sides
the only problem of this extruder
is the noise that fan do
listen the noise
it whistles
are this bars on front of fan
ok .. is easy to cuts off them
power off because the noise disturb :)
the electronics
is a Melzi v2-05
all on board .. same of the X3S
sdcard put here
there is a cover panel with fan
big lcd
power supply by 30 amperes (12 Volt)
with self-regulating fan
it start to noise
when ..
you start hot the bed
after the temperature reaches to setting .. the noise slow down
the firmware is already installed
after you connect all
and if all connected right .. works
on the guide there is an error
the guide named this motor X
and this Y
is the opposite
this is X
and this Y
you realize why the axis moves in the opposite direction
first print .. second print
made with sample filament
that comes with print .. 5-6 meters
and I start with this filament
both are at 0.1mm
are taken without any cleaning
some filaments
some setting error on extruding
the print is very precise
ghosting effect completely absent
here the mini cat
are printed very .. very well
first and second print !!
here I change the plastic
all orange objects are at 0.2mm
the finish is very good
I had a bit of spinning(wire) problems
easy to remove
with this plastic
I still have to figure out how to set the extruder for this plastic
with this other .. the problem was minimal
here I increase the retraction
and .. there are improvements
after, I tried this with same retraction of this .. 4mm
but at lower temperature and the problem worsened
this a my error on setting the extrusion
the quality of print
and .. the printer movement .. is excellent
these are for new project
printed so
with some spinning that I cleaned
look the print finish .. is very good
and much precise
well we comes to the end
as you can saw by the prints
the mechanics of this printer works very well
the components seem of good quality
you only need to be careful about assembly
I suggest you use a set square
to check the orthogonality
pay particular attention to the x axis
that it need to has the two belts at same stress (tension)
in conclusion the vote for this print is ..
I suggest it
if you are interest, in description you can found a coupon with a little discount
if you already has it
follow me because it will become my main printer
I will make changes and improvements
to follow a fast unboxing with music
bye, to next video
