End Effector

The new end effector kit is sold as a "kit of kits". Each individual bag of parts is available as a separate kit on Amazon.com, in case anyone needs spare / replacement parts.

From the bag labeled: "End Effector Rebuild Kit", remove the 3 pieces of the end effector housing.

NOTE: It may be easier to install these nuts and screw one at a time.

Insert 6x M3 Nuts into position shown.

Secure nuts in position with M3 x 8mm SHCS, threaded in 3-4 turns.

We are just using these M3 x 8mm SHCS to temporarily hold the M3 nuts in place; they will be removed later, so no need to tighten the screws all the way.

Alternative technique would be to slide the assembly off the table and insert the screws from the bottom, using gravity to hold the nuts in position while the screws are installed.

Using the round hole for the auto levelling probe, rotationally key the end effector PCA to the correct orientation.

Note: Some beta testers reported that it is easiest to lay the PCA down on the work surface with the connectors facing up and carefully press the plastic housing down over the connectors, working at clearing one connector at a time.

Flip the subassembly back over with PCA side facing up, and give each SHCS a tug to ensure that each nut is properly seated within its hexagonal cutout.

Press the end effector PCA all the way down against the plastic.

Flip the plastic back over again, until PCA side faces down.

Install 8x M2 nuts as shown.

As you install each nut, secure it by inserting an M2 x 6mm SHCS and an M2 washer from the opposite side.

Remove the M3 x 8mm nuts installed in previous steps to secure the nuts; these nuts are now fully captured and can't come loose.

Lightly tighten down all the M2 screws onto their pads on the PCA.

You have just completed the electrical wiring terminals for the end effector. Due to the low height requirement, we are using this "screw terminal" design for connecting our power and signal lines.
