  Suggested limits. A person must confirm every limit before this device can be written.
  The V-Core 4 runs Klipper and Moonraker on RatOS. RatOS starts with the host name RatOS and asks for a new
  one during setup, so set host and match.moonraker to the name you chose. The limits suit PLA, with the
  hotend at most 215 degC and the bed at most 60 degC.
