Hi guys, today we try a interesting printer
the FLSUN F3 that gearbest send me
also send me a spool of green tpu, by sunlu
and a spool of nylon .. by kcamel
well .. let's see how it went
then .. the electronic
is MKS v1
a known electronics
comes with 4 drivers .. already mounted
but you have 2 other drivers not mounted
the color is different but are same type
It is a fully equipped electronics, use atmega2560 processor
we have 4 mosfets
one for the bed .. 2 for extruders
and one for fan
6 endstop ... 3min, 3max
here the 3 temperature sensors
bed and the 2 hotend
here 2 outs for the servo
I read 2 .. maybe it more
the good of this electronic is that it comes with standard open firmware
it comes with a standard Marlin version ... 1.4
configured for this board
so .. if you want modify it you have open code to modify and ready to upload
it also a good base to have the board config if you want try newest firmwares
so .. good
here the lcd display
capacitive type
with big sdcard reader
and usb host plug
the heatsink
an adapter to connect in series the 2 z motors
a proximity sensor for autoleveling
well .. the extruders group
is much equipped
we have an single extruder
the type with ptfe tube inside (e3dv5 size)
with an additional nozzle
hole 0.4
for replacement
we have other 2 nozzles .. one is 0.3 and one is 0.2
we also have the mixer extruder group
so ..
this is the head to mixer the filaments
or you can use with 2 separate head
after .. we have ..
a heating cartridge for this
and 2 .. ptfe tube with adapters
we also have the 3th tube for this extruder
emm .. this is the 2th motor for the 2th extruder
ok guys, let's say there's a nice set of options
we have a cube frame
well rigid with full "angular supports" on all angles
the mechanics is classic xy
the steal rods, the ballbearing comes in good condition
supports for motors are in metal
but ..
the y motor support
is on plastic support and there are little oscillating when run
no optimal
here the extruders
and .. I not like it
use old sistem
the change of filament not easy
when you change the filament
you need dismount this and I use a screwdriver to help me insert the filament
really ... bad
the bed is 30x30 cm
but real print area is 26x26 cm
indicatively .. the hole of the screws
the bed heating quickly
because it have 0.5 ohm of resistance .. very low
it use around 24 amperes
that are ~290 watt
and there is heating of the cable when run
for me this is exaggerated (no good)
the resistance is too low
then .. a problem that I found are these bar
that they had wrong holes
so .. I rotate the bar where no holes and mark the holes with pen
and I made new holes
look here the misalignment
of the holes
the works are been do on both of the bars
here the endstop
the z endstop on this bracket not good .. it can move easily
well .. in my test I try the "cyclops" extruder
because I think it's the most difficult to make to work
on the mixing of the 2 colors
compared to the chimera that is the 2 separated extruders
now
here I tried ..
to do a dual colors print
but the cyclops extruder is not good for this type of prints
it need a very large "change colors tower" to change a color
for this type of work is preferable the chimera
the 2 separated extruders
and I left this kind of prints
here some test
a problem of this kit, is not have a cooler for the pieces
so .. some artifacts are due because
I used simple fan on one side and this is not optimal
and the other side not have cooling .. and inside
the print seem good on the mechanics movements
I not had block problem
here ... a rocket
the change color is not rapid
especially in the case of a dark color towards a light one
on the contrary, it works better
dice with 20 faces
nice
here a paper cup holders
well .. start to say that kit is not for newbie
the kit is interesting
but require you already have a some skill
on arduino, flash of the firmware
and on the print process
it comes with 3 type of extruders
so you have many possibility
the electronic and the display are very good
the kit have some faults
and .. in general is a little bit raw
so .. you need to refine .. and make it beautiful
now the mechanic is not optimized
if you rework the carts
and the rods holders
is possible to enlarge the print area to around the 30 cm
30 x 30 cm
I'll think to do something with this kit .. some mods
but that mods will completely change the printer
I have half idea to move all inside of the cube .. I don't want nothing outer of cube
to close all
and ..
I like the corexy
so ...
change the mechanic into corexy
obviously this will have calmly .. in spare times
this is all
to follow, an unboxing
bye .. to the next ..
