Dual Switching Extruder Servo rotating no ooze

It appears to be a user manual for building and setting up a dual extruder 3D printer. The text describes the process of assembling the modular x-carriage, attaching the hotends, calibrating the printer, and configuring the board connections. Here's a breakdown of the content: **ASSEMBLY** * Printing parts with PETG * Assembling the rotating hotend front and back with the hotends inside * Mounting magnets into the hotend front cover and carriage * Inserting the rotating hotend into the carriage * Centreing the servo at 90 degrees and adjusting its movement range **CONSTRUCTION** * Printing all parts with PETG * Using Simplify3D multi-process to minimize support material * Assembling the modular x-carriage * Attaching the rotating hotend onto the modular x-carriage * Lowering the nozzles to the bed (glass) * Mounting the nozzle shields and securing them at 20 degrees to the bed * Mounting the parts cooling fan **BOARD CONNECTIONS** * Running a MKS Base V1.5 board * Configuring Servo0 for BLTouch on PIN 11 * Using PIN 12 for Servo1 that operates the servo to switch the Hotend * Redefining any of the X, Y, or Z + endstops as a servo for the hotend in PINS.h or similar The user manual also provides some additional tips and recommendations, such as: * Printing a dual extruder calibration test to measure offsets in both the X and Y axis * Using large pliers to snug fit the magnets into the carriage without glue * Not using heat to avoid demagnetizing the magnets at 80C Overall, this user manual appears to be well-organized and provides clear instructions for building and setting up a dual extruder 3D printer.
