Mendel90 Kit Instructions

The build is broken down into sub assemblies that can be worked on sequentially by one person, or
in parallel if there is more than one person building. For this reason each assembly begins on a new
page so the instructions can be separated.
All the diagrams can be viewed in Open CAD allowing real time zooming, rotating and panning to
get the best view.

1. General Build Tips
•X is left / right. Y is backwards / forwards. Z is up / down.
•Bar lengths: The longest and shortest bars are the Y bars. Of the two pairs left, the longer
ones are the X axis and the shorter two the Z axis.
•The longer belt is for X and the shorter one is for Y. They are supplied cut to the right
length.
•De-grease the rods that come with packing grease. Acetone or methylated spirit works. The
grease will be scraped off by the bearings anyway and will prevent the bar clamps from
getting a firm grip.
•All screws have a plain washer where they meet the plastic, to spread the load and prevent
the plastic being chewed up by the rotation of the screw head. Most fixings have a captive
Nyloc nut to prevent them vibrating loose. It is very important that the nut is fully seated
in the nut trap while the screw is inserted. They are quite a tight fit, so sometimes it is
necessary to pull or push them in with a long screw. The M3 x 45mm screws in the kit are
handy for this.
•The X and Y bar clamps should not be over tightened, i.e. do not close the gap fully or the
parts will break. The Y and Z bars only need a light clamping force because the only force
trying to slide them is the bearing friction.
•Washers tend to have a smooth side and a side with a burr from being stamped out. Make
sure the smooth side faces bearings and belts.
•Ribbon clamp notation is <number of wires>_<hole size>. There are three lengths: the short
ones are 14 way for the X axis, the medium ones are 20 way for the Z axis and the long ones
are 26 way for the bed. An N suffix denotes with nut traps. B denotes no slot.

Tools Required
•panners: 5mm, 5.5mm, 7mm & 13mm.
•Allen keys: 1.5mm, 2mm, 2.5mm, 3mm & 6mm.
•PZ 1 Pozidriv screw driver.
•PH 1 Philips screw driver.
•mall flat blade screw driver (for Melzi screw terminals).
•Vice (to close IDC D type connector).
•Wire cutters.
•Wire strippers.
•Needle nose pliers.
•oldering iron.
•Digital callipers.
•quare (to messure if things are 90º, just to be safe :-D )
Recommended
•Multi-meter with thermocouple attachment
•Dial gauge
•Wire brush
Consumables
•ticky tape, oil, white lithium grease, glass cleaner (e.g. vinegar), lint free wipes.

Assembly
Note that this view is from the back of the machine.
1. Attach the 6 fixing blocks to the base with a kebab of No6 pan wood screw and M4 Washer
and a M4 star washer, the star washer goes on the screw first and the washer last so when
screwed in the washer will touch the fixing block first. You might want to stop just before
the washer grabs the fixing block so you can push it later on.
2. Attach the 4 fixing blocks to the gantry with the same kebab of washers and screw
3. tand the gantry sheet on the base and screw it in at the 4 fixing blocks with the same kebab
of screw and washers and stop screwing in just as before.
4. Take one stay and screw it to the fixing blocks in the base and gantry in just the same way
5. Repeat with the other stay
6. Now with a square tighten the screws in so they are just tight. DO OT OVER-
TIGHTE . tart with the gantry then the stay. They should be 90º to each other by design
but might need some help hence the square

7. Loosely attach the two ribbon clamps. The longer one goes at the back of the base for the
bed wires. The shorter one goes at the top of the gantry for the X axis cable.
8. Loosely attach the two AB Cable Clips. One at the front and one at the foot of the gantry
9. Loosely attach the CA cable clip near the long ribbon clamp at the back.
10. Loosely attach the AD cable clips at the top of the gantry at each side.
