First, unplug the power cord and remove the backing from the Replicator 2X (see photos). The filament guide tubes and cables pop out easily and can be moved aside. Then, loosen the screws on the z-endstop and slide it down to a lower position - roughly 3.2mm lower, although you can adjust the bed leveling screws later to get the nozzle height just right. (We have our z-endstop moved all the way down, as you can see in the photo.) Once your z-endstop is in the desired position, tighten the screws. (Make sure the z-endstop is securely fastened, as a loose z-endstop could cause the bed to rise too far.) Run the bed leveling routine and adjust your bed leveling screws until you're getting light resistance when sliding a piece of standard copy paper between the bed and the nozzle. That's it - you're all set! If you run into any trouble with this process we can absolutely help walk you through it - just email us at in...@buildtak.com.
