Tower Construction

There are three towers that support the three moving arms of the printer. For each tower you will need the following parts:

# Component Qty Type
934 Smooth rod 8mm x 426mm 2 Hardware Fisher 001
408 NEMA 17 stepper motor 1 Hardware
1305.1 Motor bracket 4 Printed part
112 M3x25mm cap head screw 4 Fasteners
212 M3 plain washer 8 Fasteners

 

TIP: There’s a list of the Fisher printed parts on THIS PAGE. Click on the ‘Location’, to see a preview of the printed part, if you are unsure what it is.

 

NOTE: The smooth rods should have clean chamfered ends, free from burrs, so they can slide easily into the relevant parts without causing any damage. Check all the ground bars before proceeding and file any burrs away as necessary. You may damage the linear bearings when you fit them if you do not do this.
Push two printed motor brackets onto the end of each smooth rod. Note the orientation, and that the bracket closest to the end of the rod should be flush with the end. Push two printed motor brackets onto the end of each smooth rod. Note the orientation, and that the bracket closest to the end of the rod should be flush with the end.
Screw a M3x25mm cap head screw, through two washers and the motor bracket, and into the motor.

The screws and washers, when tightened, hold the rods in place so they cannot slip through the motor bracket.

Note that the motor wiring connector should come out sideways, not up or down.

Add a second M3x25mm cap head screw into the top bracket. Slide motor bracket so it lines up with the hole in the motor, and tighten.  Add a second M3x25mm cap head screw into the top bracket. Slide motor bracket so it lines up with the hole in the motor, and tighten.
Repeat for the other side.  Add/remove washers as necessary to ensure the rods can be securely clamped.  Repeat for the other side. The screws and washers, when tightened, hold the rods in place so they cannot slip through the motor bracket. Add/remove washers as necessary to ensure the rods can be securely clamped.
You need to build three towers in total, so repeat the above twice more.

You will need two with motor wiring connectors on one side, and one with it on the other side. See the picture for orientation.

Base Plate Assembly

The base plate holds the electronics. You will need the following parts:

# Component Qty Type
1299 Base Plate (5mm acrylic) 1 Laser cut Fisher Base Plate Assembly Components
744 Duet PCB spacer (5mm acrylic) 4 Laser cut bag
6200 Duet Maestro PCB (photo shows older version) 1 Electronics
258 M3 Nut 4 Fasteners
1186 M3x16mm button head screw 4 Electronics Bag
212 M3 plain washer 4 Fastener
All acrylic parts are covered by a protective film, on both sides. Always remove this before assembly.  All acrylic parts are covered by a protective film, on both sides. Always remove this before assembly
There are four holes in the base plate, for mounting the Duet PCB. Push an M3x16mm button head screw through each one, and put a Duet PCB spacer and M3 washer on each on.  There are four holes in the base plate, for mounting the Duet PCB. Push an M3x16mm button head screw through each one, and put a Duet PCB spacer and M3 washer on each on.
Place the Duet on these, as shown. Fasten the Duet in place with the four M3 nuts.  Take care not to damage electronic components on the board when you tighten the nuts.  Place the Duet on these, as shown. Fasten the Duet in place with the four M3 nuts.

 

Base Assembly

Assemble the lower part of the printer. You will need the following parts:

# Component Qty Type
Motor towers 3 Assembled Fisher Base Assembly Componets
Base 1 Assembled
1245 Kinematic Mount 3 Printed
242 M3x16mm cap head screw 6 Fasteners
Push the motors up through the base plate. Be careful to support the rods when doing this; acrylic can be quite brittle so you don’t want the ends to move around.

Note the orientation of the motor connectors to the Duet; fit them as shown and this will make wiring them up much easier.

   Push the motors up through the base plate.
Using two M3x16mm cap head screws on each, screw the three kinematic mounts onto the base plate. The screws should self-tap into the plastic of the printed motor mount underneath.  Using two M3x16mm cap head screws on each, screw the three kinematic mounts onto the base plate.
