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) On RatOS during the Initial Configuration for the Hybrid, make sure to select "Rat Rig V-Core 4 Hybrid" in the printer selection.  
Note: Size of the machine chosen is not important as it will be overwritten later.

2) During the configuration process, remember to select the SuperPinda Z-probe and complete the configuration.
3) Next, select your machine size using the buttons below. Depending on your browser, the file will either open directly or download. In either case, copy all of the text and paste it into your printer.cfg just above the line which reads
  `<---------------------- SAVE_CONFIG ---------------------->`.
  This will override the selected VC4 configuration with the required VC3.2H values.

4) Save and restart.
5) Return to the commissioning process.
6) When you reach the Home Sequence chapter, instead refer to the V-Core 3.1 Z-offset chapter linked below.

7) After completing the V-Core 3.1 Z-offset chapter, skip to the Bed PID chapter inside of build plate preparation section of the V-Core 4 commissioning guide.

8) Do not follow the Switch to Performance Mode chapter unless you have active cooling for your Octopus mainboard and stepper motor drivers.
9) Skip the Beacon Set-up section of the Calibration chapter.
10) You may continue to use your existing slicer profiles, or alternatively, you can use the official V-Core 4 Hybrid profiles in PrusaSlicer.
