Airtripper's extruder drive is used on the MOST Delta, you are encouraged to visit the developers page to learn more about it.
- Ream the 3mm holes in the drive body and linking rod with a 3mm drill bit.
- Place the Mk7 drive gear on the motor with the set screw on the motor-side of the shaft.
- Place the MR105z bearing on the shaft above the drive gear.
- With the motor laying on the table, wires exiting towards you, orient the drive body so that the hole at the base of the conical section is towards your left and the four mounting holes in the body are aligned with the holes in the motor.
- Start the M3 x 6mm button head screw in the top-right hole.
- Start the M3 x 25mm screw in the top-left hole.
- Place the linking rod over the remaining mounting holes on the side nearest you such that the screw head recesses face up. Start a pair of M3 x 35mm screws into the mounting holes.
- Tighten all of the screws except for the floating end of the linking rod, firmly affixing the drive body to the motor.
- Cut off the circular base from the printed idler shaft and smooth and round that end of the shaft.
- Push the shaft through the 608zz bearing and snap the shaft and bearing into the idler cap.
- The drive uses the small piece of rubber fuel line as a compression spring. Two holes that align with the openings at the end of the idler cap opposite its pivot point must be drilled. Align the rubber hose with the end of the cap and mark the positions of the holes with a 3mm drill bit.
- With a 3mm drill bit, drill two holes completely through the hose where marked.
- Place washers onto a pair of M3 x 40mm screws and push the screws through the hose so that their heads are on the same side of the hose.
- Place the idler cap on its pivot (the scew under the floating end of the linking rod) and push the M3 x 40mm screws into the matching holes in the body.
- Start a pair of M3 nuts on the ends of the screws and tighten such that the hose is somewhat compressed.
- Set the assembled extruder aside.
