Sscherbinski: /* 3D Printing Parts Sign-Up */

== General Info ==

Pick and Place machine capable of placing parts as small as 0603 (possibly 0402). Optimized for prototypes & small/mid-scale manufacturing. Works with [//openpnp.org/ OpenPNP] for operation, so a PC is required.

* Max board size: 225mm x 400mm
* Max part weight: 25 grams
* Max part height: 20mm

This machine is a '''v2'''. The latest version is v4, but upgrading from v2 to v4 is not trivial, and v2 will probably serve our needs just fine.

In general, the pick-and-place process can sometimes require tuning. Have extra parts and boards available for the inevitable mistakes, and consider using double-sided tape to do a test placement run before breaking out the stencil & solder paste.

For double-sided PCBs, you will need to run the first side with higher-temperature solder paste, and the second side will have to use a lower-temperature paste. Also, when running the second side, your stenciling, PCB holders, and hot plate/reflow oven will also have to accommodate the parts on the first side when working on the second side.

== Machine Version, Docs, and General Links ==

The version we're focusing on is '''v2'''. Feeders are not included in the kit, but can be added on.

* [//docs.opulo.io/byop/ General assembly docs link]
* [//github.com/opulo-inc/lumenpnp/releases/tag/v2.2.0 Github Release Page (BOM, firmware, PCBs, STLs)]

== Adding Feeders ==
Feeder parts (NOT YET ACQUIRED):
* [//www.opulo.io/products/feeder-cable-adapter?variant=46423886692539 Feeder Cables]
* [//www.opulo.io/products/slot-harness-kit?variant=44547065741499 Feeder Kit]

Without purchase of the above two parts, we will be using strip feeders, which take up space where the PCB mounts.

=== 3D Printing Parts & Info ===

The [//github.com/opulo-inc/lumenpnp-archive/releases/download/v2.1.3/FDM-8000_corndog.stl Calibration corndog] is not included in the official STLs.

[//github.com/opulo-inc/lumenpnp/releases/download/v2.2.0/LumenPnP-STLs-v2.2.0.zip STLs from Github] (~40MB ZIP File)

[//docs.opulo.io/byop/mechanical-assembly/1-printing-parts/#material Material info] from the docs:

<blockquote>
These parts are designed for PLA, however, some folks have printed the parts successfully with PETG. You'll need about 1 kg of the primary filament.

There are three situations where you'll need specific filament colors:

* White or transparent filament for the light mounts, top-light-mount and bottom-light-mount. These parts act as light diffusers for the ring lights.
* White or light colored filament for the nozzle-rack. This helps with setting up the automatic tool changer.
* A darker filament for the Z gantries, z-gantry-left and z-gantry-right. This helps the bottom camera distinguish the nozzle tip from the rest of the gantry. If you print in a lighter color anyway you can use a bit of blue painter's table on the bottom side of the gantry.
</blockquote>

Be sure to check [//docs.opulo.io/byop/mechanical-assembly/1-printing-parts/ the docs] for printer settings.
