Congratulations to the purchase of a CNC machine of our Pro Line.
Preface
Please read thoroughly the entire manual as it contains important information about the
assembly and operation of the CNC machine. Have a look at all parts delivered and tick them
off on the provided part list. The CD within the parcel contains additional photos of the
assembly process.
If you have any questions, please don’t hesitate to contact us: 07952/92 12 79 7
All screws are to be tightened only slightly. Once the machine has been assembled
completely, the screws need to be tighted when all moving parts have been adjusted during
the first operation of the machine.

Frame assembly
Required tools: Torx T40
Cordless screw driver
Oil/grease
Required parts: Strut(s) work area
Frame parts front/rear face
Frame parts corners
Frame parts sides
18/20 profile connectors
4 mounting feet
4 plastic caps
Firstly, threads are formed in the frame parts using a screw M8 or a thread moulder M8. This
will make it easier to screw in the Torx screws of the profile connectors. Using some oil or
grease on the screw/thread moulder will then require less effort to form the threads.
Mount all 18/20 profile connectors into the frame parts front/rear face, sides and strut(s) work
area as shown in Figure 1.
Figure 1: Profile connectors mounted on the parts front/rear face, sides and strut(s) work area
Ensure that the sliding blocks slip into a groove and that the headless screws are level with the
top side of the sliding blocks. Screw in the Torx M8 screws into the frame parts but leave a
gap of approx. one millimetre between frame parts and sliding blocks. The sliding blocks
should now “rattle” with a bit of backlash.

Mould the threads in the parts corners in the same way as you did at the frame parts. Please
do not screw in the mounting foots in these parts yet. That will be done later.
Then, lay out all frame parts, the four corners and the strut(s) on an even surface where the
entire machine will be assembled. Now, start with one frame part side and a corner, and slide
the profile connectors of the frame part side gently into the groove of the corner part until
both parts lay even on the surface. Continue with the frame part rear face and mount it on the
corner part of the already assembled frame. Afterwards, mount the second corner part on the
other side of the rear face. Then, take the remaining frame part side and mount it on the
previously assembled corner part.
You must slide the strut(s) work area into the lower groove of the frame between the frame
part sides. Only then should you assemble the remaining two frame parts corner and the front
face.
Once all parts have been mounted together, the headless screws of the profile connectors need
to be screwed tightly so that all frame parts are firmly attached to each other.
If there are any gaps between frame parts after all headless screws have been
tightened, then the Torx M8 screws of the profile connectors need to be screwed
in further.
The frame is now assembled and should look like
the one shown in Figure 2. Because the frame is
laying on the work area, the mounting feet should
be screwed into the frame parts corner. After that,
the frame can be set on its feet and the plastic caps
can be plugged into the corner parts. That
completes the assembly of the frame.

Guide rails Y
Required tools: Allen keys 5/6
Open-end wrench (flat) size 13
Required parts: 2 guide rails Y
2 guide bearings
12/16 slide nuts M8
12/16 screws M8×20 or M8×22
Place 6/8 slide nuts into the lower grooves of both frame parts sides. Afterwards put one
guide bearing on the guide rail Y and mount it with screws M8×20 or M8×22 on the frame
part side. Repeat this task for the other guide rail Y (Figure 3).
To adjust the guide bearings follow these steps: Tighten the screws (with a flat open-end
wrench size 13) of the ball bearings. Then, use an Allen key turn the headless screws of the
ball bearings while checking the ball bearings. Turn the headless screws just until you cannot
turn the ball bearings anymore by hand. The adjustment is completed when the guide bearings
can only be moved on the guide rails with some resistance (Give the guide bearing a little
push. It should come to a halt within 20 centimetres).

Threaded spindle Y
Required tools: Allen keys 1,5/2/2,5/3
Required parts: 2 flange bearings
4 slide nuts M6
4 washers M6
4 screws M6×25
4 spacing rollers 7 mm
Place four slide nuts M6 in the lower groove of the frame part rear face and mount two flange
bearings with screws M6×25, spacing rollers and washers (Figure 4).
Figure 4: Two flange bearings mounted
Required tools: Allen key 5
Required parts: 2 threaded spindle (long)
4 jackets (for threaded spindles)
12 headless screws M3
Thread locker
4 POM (polyoxymethylen) nuts 126
Remove the jackets from the ends of the threaded spindles and turn three headless screws in
each of the four jackets. Screw two POM nuts on each threaded spindle. (Once the jackets
have been put onto the threaded spindles, the POM nuts won’t fit anymore!) Give plenty of
thread locker on the ends of the threaded spindles (not on the headless screws in the jackets),
put the jackets back onto the threaded spindles and fasten the jackets with its the headless
screws (Figure 5 and Figure 6).

Required tools: File

Required parts: Pre-assembled threaded spindles (long)
2 belt pulleys T5 20z (drilling 12 mm)
8 headless screws M46
Belt 650 mm
2 POM nut holders M4
Slide one belt pulley on each threaded spindle. If the belt pulley get stuck on the jackets,
remove the top of the headless screws with a file. Put the ends of the threaded spindles
holding the belt pulleys into previously mounted flange bearings but do not fasten the
headless screws of the flange bearings. Lay the belt over both belt pulleys. It is not necessary
to tighten the belt at that time.
Slide the POM nut holders M4 onto the
threaded spindles and over the POM nuts.
Fasten each holder with two headless screws
on the POM nuts (Figure 7).

Required parts: 2 flange bearings
4 slide nuts M6
4 washers M6
4 screws M6×25
4 spacing rollers 7 mm
4 headless screws M4×6 (for belt pulley)
Belt pulley T5 20z (drilling 12 mm)
Belt 305 mm
Slide the belt pulley onto one of the threaded spindles already mounted inside the machine’s
frame and put the belt onto the pulley. Plug the spindles into the flange bearings.
Place four slide nuts in the lower groove of the frame part front face and mount the flange
bearings with screws M6×25, spacing rollers 7 mm and washers in the machine’s frame.
It may be necessary to hit the flange bearings with a small rubber mallet to
adjust the position of the ball bearings and plug in the threaded spindles more
easily.
Align the threaded spindles so that they do not touch the frame parts front face or rear face
and fasten the headless screws of the flange bearings on that side of the frame where the
motor will not be mounted (Figure 8).

4 lock washers 6 mm
4 screws M6×40
4 spacing rollers 15 mm
Place two slide nuts in each of grooves of the frame part front face near that threaded spindle
that has a belt pulley on it. Afterwards, mount the motor plate Y at the front face (Figure 9).
The exact position of that motor plate will be determined later.

Slide the belt pulley onto the shaft of the stepper
motor, leave a gap of 0.5 to 1 mm between pulley and
motor casing, and tighten the pulley’s headless screw.
Figure 11: Stepper motor with belt pulley
Mount the stepper motor onto the bottom-left corner
of motor plate Y using a screw M4×45, spacing roller
25 mm, lock washer 4 mm and a screw nut M4. Please
note the direction of the wires coming out of the motor
casing (see also Figure 13).
Figure 12: Mounting stepper motor on
motor plate Y
Then, lay the belt, that is already on the pulley of the
threaded spindle, over the stepper motor’s pulley and
mount the motor with a second screw M4×45, spacing
roller 25 mm, lock washer 4 mm and screw nut M4 on
the bottom-right corner of motor plate Y. It may be
necessary to move the motor plate closer towards the
threaded spindle to get the belt onto the stepper
motor’s pulley.
Figure 13: Motor plate Y aligned
Afterwards, the motor can be mounted with the remaining two screws but do not tighten the
screws, yet. Align the stepper motor in such a way that the belt pulley does not touch any
spacing roller and tighten the screws on the stepper motor slightly. You do not need to tighten
the belt at that time. Please leave the screws used to mount the motor plate Y onto the front
face only slightly fastened.
