Note: The amount of parts
is always times 1, except if
the amount indicates some-
thing dierent. Make sure
you have al the parts before
you start with the next step.

1. Remove the protection foil from the dibond and plexiglas
3. Put the Ball Bearings in the countersunk holes on the front,
left, right and backplate. Make sure you do not damage the
dibont and plexiglass plates. This is a total of 8 Bearings
4. Use a rubber hammer or
use wooden plate between the
hammer and bearing to get the
bearing in place, make sure the
anges ush with the plate.
2. Remove all material left over by the machine.
5

5. Take 35x M3 square nuts and place
them in the T-slots of the front-back, top
and bottom plate. use pliers or tweezers
to make sure the nuts are tted correctly
in the frame
7. Red Endstop on the left
plate (that’s plate with
the extra motor holes).
make sure the lip is facing
upwards (check photo)
6. Attaching the 3 end-
stops with 6x M3X12MM
(rm but not excessive
torque!
6

8. The blue end stop on the top plate.
The lip pointing inwards. 9. The black Endstop
on the back plate on
the bottom of the pla-
te. With the lip pointing
to the right.
7

10. Turn the Front pannel around
so the T-slots are visible. Now
clean the back of the front pannel
with acetone or alcohol, so the
LED strip will stick better.
11. Install the LED strip in
the machine. Remove the
stickytape from the rst LED
strip and start at the bottom
right of the plate. Then move
up wards until you reacht the
top right corner.
12. The second part of the LED strip
goes on the top of the front plate,
start at the right and go to the top
left corner.
13. Make extra sure to
stick the LED strip very
rmly on the housing.
Otherwise, it can deat-
tach at a later stage!
push between each LED
8

14. Attatch the Top and Bottom plate to the
back plate. Make sure all the T-slots are facing
inwards. Next ad the front plate and screw
everything together with M3x16mm screws.
9

15. Place the Two sides on
the machine. Use 35 M3x-
16mm screws to secure
them into place.
16. Make sure all the cables are
guided through the holes in the
correct way. (use photo’s for
reference)

1.This photo shows all the parts needed for the sliderblocks
3. Put the two parts of the sliding
block next to each other and put
a brass bushing in one of the two
(identical parts).
4. Put some tension on the
spring lace the timing belt
with the spring in the slider
block. The timing belt comes
out the slots on both sides of
the slider block
5. Click the two parts of the slider
block together. this is a one-way
mechanisme. Check if everything
is secure.
6. Repeat this pro-
cedure four times,
this will result in 4
assembled sliding
mechanisms
2. Place the timing belt around the spring, so the teeth are to the outside.

B1. Sliderblocks

7. Screw a setscrews in all the 8 axes pulleys (with the
8mm holes) and in the double 8mm pulley setscrews:
8x M4x4mm. Doing this now is much easier than later
on in the build.
9. Then slide a 10 mm spacer around it and
then a pulley. The wide side of the pulley
has to face towards the frame.
10. Next is the assembled slider block.
This is followed by a further pulley, and
nally again a 10 mm spacer. Check if its
correct using the photo
8. Slide one of the short axes through the
hole at the front left of the machine.
13
B2. XY-Assen

11. Take two of the assembled slider mechanisms and
place one around each of the pulleys. Make sure the
hole for axes to pass through is underneath the timing
12. Slide the further axle through
the plate until it is exactly ush
with the outside of the housing.
14

13. Take the other short axes and slide it
through the hole back of the left pannel. Then
take the dubble pulley and place it on the axle.
14. Place the sort timing belt on the dubble
pulley. Make sure it’s on the side closest to
the frame. this short belt will attatch to the
motor later on in the process. Now take the
long belt from the left sliderblock and place
it around the pulley.
15. The dubble pulley is followed by
an assembled sliderblock and then
another pulley.
16. Put the right timing belt around the
pulley on the back axle. Then slide the
10mm spacer around the axle. Now slide
the axes through the frame until it is ush
with the side.
15

17. The next shaft that we are going to
assemble, is the axle of the back left.
18. Slide a 25 mm bushing around the axle, it
is followed by a pulley.
19. Place the timing belt attachted to the
front left axle around the pulley. Insert the
axle through the hanging slider block.
20. This is followed by a pulley and ano-
ther 10mm slider block.
21. Attach the timing belt on the right axle
of the pulley and insert the shaft through the
housing, so that it is ush with the frame
16

22. Insert the last axle on the right
back through the housing.
23. You start with a pulley with the
narrow facing the frame. This is die-
rent from all the other pulleys. Put a
small timing belt around the pulley
24. Then slide a 10mm spa-
cer on to the shaft.
25. Followed by a pulley. With the
broad side facing the frame. and
the slideblock
26. Slide the last 5 mm spacer to the shaft and
attach the timing belt on the right side of the front
axle. Also slide the shaft through the housing until
it is ush with this. When the gantrey is put to-
gether all the screws can be tightend down rmly
17

27. These are the nessacery parts to
secure the motors. Make sure that you
take the two with the shorter axels
28. Secure the two pulleys
with the 5mm hole on the
motors with the M4x4 slugs.
the end of the pulley has to
be ush with the axle. make
sure you screw them tight
30. Attatch the small timingbelt
around the pulley. Next make sure
the motor wires are guided around
the little hook at the bottom of the
motorspacer. do this before you
attach the spacer to the frame of
the machine.
29. The wide side of the pulley
has to face away from the motor 18
B3. XY-motoren

31. Attatch the motors with 8 M3x-
25mm screws.Use 8 M3 Washers
between the screwhead and the
frame. Start with the top two screws
to make it easier to position the
motor.
32. guide all the cables, both those of
the motors aswell as the endstop ones
down throught the hole in the bottom
o f the frame.
33. Repeat this entire procedure for the other motor.19
