V-Core 3.2H Commissioning Guide

The V-Core 3.2H configuration is closely aligned with the V-Core 4. As such, the V-Core 4 commissioning guide can be used to commission the V-Core 3.2H. Please be aware of the following differences:
1) During the Initial Configuration for Hybrid chapter, make sure to select Rat Rig V-Core 3.2H in the printer selection, and select the size matching your machine.
2) The V-Core 3.2H does not use the Beacon Z-probe.  When reaching the Home Sequence chapter, instead refer to the V-Core 3.1 Z-offset chapter linked below.
3) After completing the V-Core 3.1 Z-offset chapter, skip to the Bed PID chapter of the V-Core 4 commissioning guide.
4) Do not follow the Switch to Performance Mode chapter unless you have active cooling for your Octopus mainboard and stepper motor drivers.
5) Skip the Beacon Set-up section of the Calibration chapter.
6) You can continue to use your existing slicer profiles, alternately you can use the official V-Core 4 Hybrid profiles in Prusa Slicer.

When you reach the Beacon setup configuration, please consult the Z-offset section in the V-Core 3.1 Commissioning Guide for the correct procedure.
