Hi guys, in this video we test the new 3d printer by Tronxy .. the C5
that Gearbest send me
A boxed printer with fixed bed
Unimaker style but with a more affordable price
in description you can found the link and possible coupon
well .. we start and see how it run
then .. to show better, I remove some cover .. bottom, top and this lateral
then .. the printer structure is composed of 4 alluminium extrusion bar
held together by two metal plates
this plate
and this plate .. upper
are plates by 2.5-3mm of thickness
so, they are very rigid
this simple solution .. create a good solid cube
very rigid
the bed is all metal
dimension are 220x220mm
but the printing area is 210x210mm
the height is 210mm
the bed have 110-120W of power
the dimension and the power are good to print abs
here we see the mechanics
for head movements
then .. these supports
that fix the rods and ballbearing .. are all metal
and help to fix the plate and the alluminium bar
and increase the rigidity
the extruder is type directed
a MK8
is substantially
there is a pipe with ptfe tube inside
that go into nozzle
these pieces are made in plastic
but .. well done
the fixing of the belts
look here
it shift out
they are inserted into this cut
this and this .. are two belts tensioners
that I added
to reduce the ghost effect on prints
now .. the printer was comes with some little problems
I found the screws of the bed not fixed
also this pulley was not fixed
this belt was not connected
another ..
another thing that I found
are two motors that not have back screws
I suppose that there was an error in assembling chain
these are the motors for X5S
that was mounted on a base and fixed with back screws (Z motors)
and for a error they was mounted on this printer
to solve .. add the screws
to prevent them from opening
the motors without the screws was .. one of the bed
and one was this
here .. we see the electronics
it is located in the base of the printer
is classic tronxy electronics .. with 4 drivres
it is not reprogrammable and not expandable
but it works well
we have a power supply by 12 Volts and 20 Amperes
and nothing other
now we see a some prints
then ..
first print was my calibration cube
how you can see .. there is many ghost effect
and general vibration
this is due by belts
I add the belts tensioners
and reprinted the cube
and here the result
really better
ghost almost absent
but look .. the print is not smooth
I changed the plastic
as you see the prints are good but not smooth
after, I printed two pieces together
and comes other defects
look here ... this step (stair)
same here
there is been a layer shifting
this is due to steps lost by X motor
but there are also some rifling defects
I reprinted them with different color to see better
look all these rifling
same here
well .. these is a problem of current of the motors
so, we need to correct the current of the motors
to regulating the motors currents
we need to tuning these trimmer
1.. 2 .. 3 .. 4
the trimmer .. are made with 2 legs on a side and one in opposite side
the trimmer and mainboard orientation is the same you can see here
the wheel .. have a cut on it
use this as refer
then .. for the motors .. X, Y, Z
use this conf
for the extruder
use this conf
we back to own prints
so, after I made the adjustment
these is the final result
this print was breaked by me when I remove it from the bed
I want to show you something
then .. this side
printed well
is the side where there is the air cooling
but the opposite side not printed well
these is the reason because need cooling on both sides
now .. the prints .. are very nice
same the tips .. cooling works well
very good
well .. the conclusion
the printer arrived with some problems
but easy to solve
the mechanics is well done, the frame is very rigid
I really like it
In fact, I'm already planning the first changes
the first change will be to mount an e3dv6 extruder
here you can see a first prototype
and after, I'll put it among the printers I usually use
so, if you are interested .. follow me
now the printer
comes without user guide and other software
but .. software as Cura or Repertier .. you can download from official website
woks as all other printers
if you considering the type of mecchanics
and the relative low cost
I suggest to you
this is all .. following the unboxing .. and some images of printer at work
bye .. to the next video
