Voxelab Aquila Runout Sensor (z end stop) - no additional hardware

thingiverse

If you install the BLtouch to the Aquila you will have an extra 'z' end stop floating around. This uses that end stop and turns it into a runout sensor so that if you filament snaps or runs out, the nozzle is returned to a park position. Mine was designed to require no additional parts other than a couple M3's (hence the runout is vertical with a through hole) and a zip tie (or glue and clamp). File the through hole to give a smooth transition (I used a larger drill bit and angled it to take off the top edge of the hole). The M3's utilise some pre-drilled and tapped holes that are on the extruder shelf on the Voxelab Aquila.
