USA news on Youtube Sep 30 2017

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
