# --- Hardware iteration (live Pi at onefinity.local) ---

# Rsyncs the freshly built static UI tree (build/http/) onto the Pi's
# bbctrl egg directory and restarts bbctrl. This is much faster than
# a full firmware update and is the fastest way to iterate on the V09
# UI changes against real machine state (W axis, jog feedback, etc).
#
# Defaults:
#   HOST=onefinity.local
#   USER=bbmc
#   PASSWORD=onefinity      (used for sudo on the Pi)
#
# Override:
#   HOST=10.1.10.55 ./deploy.sh hardware
