IFactory One Upgraded Semi
This is an early version of this manual. For the newest version visit: https://ifactory3d.com/support/#manual
For the assembly of many components of the iFactory
One, so-called T-nuts are used. The T-nuts need to be
pushed into the profiles groove. This only works if the
T-nut is in the correct position, as shown in the
picture.
Once the T-nut is in the groove and the component is
in place, the screw can be tightened. To create the
desired clamping, the T-nut must be turned 90° as
shown in the picture.
It may happen that the T-nut does not turn in the
groove when the screw gets tightened. If this
happens, you have to turn the screw back a little (do
not turn the screw all the way out because then you
will lose the nut!) and then tighten it again until the
T-nut produces the desired clamping.
In general, screws in plastic components should not
be tightened too much, otherwise they can break (as
soon as you hear noises, do not continue turning).
Mount the back feet
Belt group
First, the feet must be attached to the pre-assembled
belt assembly. The rear feet are already attached
to an aluminium profile and will be mounted on the
back of the belt assembly as shown in the picture.
The easiest way to mount the feet is to lay the belt
assembly on its side and tighten the pre-assembled
M4x14 screws in the feet from below. The rear feet
must be fitted so that they touch the bottomside of
the rear tensioning guides.
Back feet
mount the front feet
The front feet get mounted on the front 20x20 Profile
and are attached in the same way as the back feet.
The 45° chamfer is pointing inwards.
Foot LF
Foot RF
mounting the guide rails
The guide profiles are mounted with the small roller
holders to the aluminium profile of the back feet.
For this purpose, the T-nuts of the roller holders are
used.
Guide rails
The guide profile of the print head is pushed over the
metal rails with the pre-assembled large roller
holders. The print head must be aligned so that the
nozzle of the print head points in the direction of
the belt. If the print head guide rail has been pushed
correctly, [roller holder large R] is now on the same
rail as the [small roller holder L].
Print head
attaching the 20x20x460 profiles
Now the 20x20x460 profile with the pre-assembled
angles must be mounted to the front
feet (attention: angles are attached to the profile and
are not used to attach the profiles to the feet).
Mount the profiles on the 45° side of the feet so that
the angles on the profiles point upwards. Attach the
other side of the 20x20x460 profile to the guide rail.
Use M5x25 screws for this step.
20x20x460 Profile
mount the motor profile
Please take note of the orientation of the motors as
shown in the picture. Mount the profile on the
angles from the previous step.
Motors with profile
adjusting the motors
Now loosen the M4 (lower) screws in the X- and Y-
plates.
Then slide the plates inwards as shown in the
illustration until the side T-nuts are in the recesses of
the 20x20x460 profile (mounted in Step 5).
secure the motors
After the motors are placed, tighten the circled
screws and screw in a M5x25 screw like indicated in
the picture.
Do this Step for the Y- as well for the X-motor.
Aligning the wheels
Check if the printhead moves smoothly up wards and
downwards. If it does then go to step 9.
If rail does not move smoothly, do the following
steps:
The wheels that should be adjusted are the eccentric
wheels indicated with arrows in the picture.
Aligning the wheels
First loosen the set screws (no need to do it as far as
in the picture for now but just a bit).
Try loosening the bolt on the other side at the wheel.
Aligning the wheels
You can fasten the bolt again, when you have placed
the x rail onto the frame. Fastening the bolt again
auto realigns the wheel (it rotates along with the bolt
until the wheels hits the rail). Then fasten the set
screws.
•If the bolt doesn't really want to get loose, you can
try to rotate the disc with the eccentric hole. This
may take some force when the bolt is tight.
placing the y-belt
The next step is best done from the back of the
printer. Place the gt2 belt over the Y-stepper
motor pulley and then along all the other pulleys
on the back as shown in the picture to build a core
XY motion system. Mount the belt to the
printhead with a cable ties. Do not tension the
belt to much just prevent any sag.
placing the x-belt
Place the gt2 belt over the X-stepper motor pulley
and then along all the other top pulleys on the back
as shown in the picture to build a core XY motion
system. Mount the belt to the printhead with a cable
tie.
Do not tension the belt too much, just prevent any
sag.
tightening the x- and y-belts
Release the 4 M3 screws in each motor plate.
Pull the motors upwards as shown in the picture and
tighten the M3 screws again.
If the belt is not tentioned enough release the 4 M3
screws again and repeat Step 20 and 21 but this time
with more tension to the belts.
If the belts are tight enough, you can cut off the
remaining gt2 belt at the printhead.
Mount the corner bracket with the logo on the front
outer corners.
Belt and tightening
Pull the two back belt tightening sliders as far as
possible to the back and tight the M4 screws.
Pull the two front belt tightening sliders in the
direction of the side plates with the iFactory3D logo
and fasten the sliders as soon as they hit the side
plates*.
* For all early-versions of the printers, there are still smaller side plates, so an equal air gap of around 7mm between side plate and sliders
in needed.
rods and tightening
8mm rod
Now place the two 8mm Rods through the belt and
the bottomside of the square bar and clip it into the
fitting of the bearing brackets.
The fittings are numbered, and the rods need to be
at the same number to apply the tension evenly to
the belt.
The higher the number of the fitting, the more
tension is applied to the Belt.
rod and collar
Place an 8mm-collar to each end of the 8mm shaft
and push them inwards.
If the collars hit the motor brackets tight the headless
screws in the collars.
Mount the filament detection to the left side of the
printer below the X stepper motor.
The end of the bowdentube is now plugged into the
hole of the filament detection.
Place the spool holder on the left side between the
filament end stop and the front feet.
Do not place the spool holder too close to the
filament end stop, because this might cause the end
stop to not work properly.
Lead the cables out of the upper hole of the
electronic board (cut the zip ties from the X-Motor
cable, if needed).
Place the electronic board slightly below the filament
end stop.
drag chain holder
Mount the drag chain holder onto the right side of
the extruder with the pre-assembled screws.
Mount the cable chain to the holder and the
printhead.
Drag chain holder
Y endstop and guide rail
Mount the Y endstop below the X stepper motor as
shown in the picture.
Y endstop
Mount the display case on the front right corner of
the printer (as shown in the picture) and connect it
to the mainboard using the provided USB cable.
The other cable is plugged into the filament
detection sensor.
printing position and adjusting
In the end the printing position needs to be checked.
For that push down the print head until the nozzle
touches the belt. The Nozzle should print on the heat
bet but sometimes the nozzle is positioned between
the back shaft and the heat bed. In that case, loosen
the M4X20 screws in the scraper and push the whole
bed group in the back direction until the nozzle is
above the heat bed. Afterwards the M4x20 screws
need to be tightened again.
securing the printing position
Secure the printing position with two M3 screws in
like shown in the picture.
Note: These threads might also be in the front
position underneath the scraper.
• Mount the cables following their labels to the stepper motors. One motor cable is not labeled. This is the
cable for the Z1 motor (front Z motor).
• Plug the large ribbon cable from the mainboard box into the electronic board for cables.
• Mount the cables of the heated bed to the mainboard box.
• The Z and Y stepper motor cables, and the power plug for the Raspberry come directly from the mainboard
box and need to be connected as well.
• Connect the Y end stop directly to the mainboard box.
