Introduction
This guide covers assembly of a basic E34M1 build with a Rapido hotend, Sherpa Mini extruder, and BLTouch probe.
You should have your Mercury One build's X axis extrusion and linear rail assembled before following this guide. It is recommended that you include routing and securing the belts as part of the E34M1 build process, and will be prompted to do so.

Considerations
Time
Assembly time depends on your experience level and build configuration. Wiring and connecting the belts are not part of this guide, but some guidence is given on these topics.
Excluding wiring and belt routing, assembly time is approximately 30-45 minutes.
Heat Set Inserts
All heat set inserts should be installed before beginning this guide. The Modules & BOM section includes locations for every heat set insert included with E34M1.
Warning: Heat Set Inserts
Stock EVA 3 uses M3 x 4.6mm OD x 4mm L heat set inserts. E34M1 maintains consistency with ZeroG and uses M3 x 5mm OD x 4mm L inserts (often called "Voron inserts"). Double-check which insert you should be using for third-party components to avoid damaging or ruining a printed part.
Lock Washers
M3 lock washers are used extensively in this guide. Lock washers are not required but are strongly recommended to prevent loosening screws.
To emphasize that they are optional, lock washers are italicized in the guide's Parts lists.
