By the end of this section, you will have assembled the base of the printer. |
Tower assembly
There are three towers, that support the three moving arms of the printer. You will need the following parts:
|
TIP: There’s a list of the Fisher 1 printed parts on THIS PAGE. Click on the ‘Location’, to see a preview of the printed part, if you’re not sure what it is.
NOTE: The ground bars 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.
Base plate assembly
The base plate holds the electronics. You will need the following parts:
All acrylic parts are covered by a protective film, on both sides. Always remove this before assembly. The Duet PCB spacers are cut into the base plate, and are attached by a small sprue. Remove them for 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. | |
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:
|
Push the motors up through the base plate. Be careful to support the rods when doing this; acyrlic 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 will make wiring them up much easier. | |
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. | |
Your printer should now look like this. |
