homing on a breakout board

[tcurdt]

To test a few things I have a breakout board that runs grblHAL. Now I need homing - but unless I connect 3 limit switches and press them accordingly I (of course) get a

ALARM:9 (Homing fail. Could not find limit switch within search distances. Try increasing max travel, decreasing pull-off distance, or check wiring.)

Is there some kind of short cut for development/tinkering to convince grblHAL that home was reached without manually pressing some limit switches?

Enable manual homing for all axes:

$22=33
$44=0
$45=0
$46=0

Then send:
$H
when in the home position.
