¶ HOW TO GET HELP
If you need assistance with your build you can head over to the DOOMCUBE Discord server and post your questions (typically in the #micron_build_questions channel). It is the primary help channel for the Micron! You can also check the Github page for the latest releases.

|---|---|---|---|
| BUTTON HEAD CAP SCREW (BHCS) | FLAT HEAD CAP SCREW (FHCS) | SOCKET HEAD CAP SCREW (SHCS) | GRUB SCREW (GS) |
| Metric fastener with a domed shaped head and hex drive. Most commonly found in locations where M3 fasteners are used. | Metric fastener with a cone shaped head and a flat top. | Metric fastener with a cylindrical head and hex drive. The most common fastener used on the Voron. | Metric Socket Cup Point Set Screws (also called Hollow Point Grub Screws) are fitted with a concave cup point, which allows them to fit closely against a rounded surface such as a motor shaft. |

| M3 HEX NUT | HEAT SET INSERT | SELF TAPPING SCREW | PULLEY |
| Hex nuts couple with bolts to create a tight, secure joint. You’ll see these used in both M2 and M3 variants throughout this guide. | Heat the inserts with a soldering iron so that they melt the plastic when installed. As the plastic cools, it solidifies around the knurls and ridges on the insert for excellent resistance to both torque and pull-out. | Fastener with a pronounced thread profile that is screwed directly into plastic. | GT2 pulley used on the motion system of the Micron. | |

| A ball bearing with a 3mm ID and flange for containing the belt used in various gantry locations. | A ball bearing with used in the Z drive. | Steel shaft, 5mm in diameter, 47mm-50mm long with a flat ground on it used in the Z drive shaft assembly. | Not to be confused with stamped washers. These are used in all M3 call-out locations in this manual. |

¶ Blind Joints
BLIND JOINT BASICS
Blind Joints provide a cost-effective and rigid assembly method. The head of the BHCS is slid into the channel of another extrusion and securely fastened through a small access hole in the extrusion. If you’ve never assembled one before we recommend you watch the linked guide.
¶ Extrusion Prep
SORT EXTRUSIONS
Collect your extrusions and sort them by length. We will highlight the extrusions used in each step and label them as shown on this page.
EXTRUSION CALL-OUTS
To avoid confusion, we will call out the extrusions by the names shown on these reference pages. To help assembly along you may want to label the extrusions or print the reference page for a faster lookup
(Note: the scaling of the images might not function as intended when viewed on mobile screens. Refer to measurements and references below.)

(!!!! Need to find a convenient way to implement this system in the wiki. Below callout could be one way to do it.)

¶ BED EXTRUSIONS?
Some frame kits come with bed extrusions that are mounted using blind joints. These will end up being 2 longer extrusions and 8 B extrusions.
MULTIPLE VIEWS
The views shown are the left, front, right, and bottom views of each extrusion.
ALL UNITS ARE METRIC
If a unit is not specified assume it’s metric.
