Hi Everyone, I managed to solve two problems in one with this little print.
Re-using the redundant z-limit switch sensor as a filament run-out sensor, and routing my filament nicely from my filament drying box via top gantry into my Sprite Pro. I remixed an existing file from Printables: https://www.printables.com/model/298272-ender-3v2-filament-runout-sensor
The filament guide uses a short section of PTFE tube and a coupler for smooth operation.
I extended the switch cable and routed it in the extrusion grooves.
I am using a 4.2.2 board with Kilpper, and added the following into the printer.cgf file.
