Z-axis mécanical limit for Hephestos 2

thingiverse

Here is a rewritten version of the text in American English: A Mechanical Finish for Hephestos 2: Axe Z The inductive sensor detects the metal plate or rather the metal underneath the glass. If you forget to install the plate and ask the panel for a function, the head will descend to measure the 0 Z coordinate and never find it. Let me think about that... There's a risk of damaging the inductive sensor on the plate support or throwing the Z-axis bearings out of their rails... :(( The principle behind this modification is to mechanically limit the movement of the head with two screws positioned a few mm below the 0 position of the nozzle. In this way, if the glass plate is absent, the head cannot descend too far and avoid any potential damage. On either side of the Z-axis screws, the two tightly screwed screws are covered with a cache that serves as a shock absorber in case of an impact (PLA against metal) and also for aesthetics to cover the screws. Assembly: Place the two screws and the cache on the threaded rod of the Z-axis (cache on top). Tighten the screws until they reach their lowest point (against the motor coupling). Position your head at 0mm and mark a reference point on the Z-axis screw at the height of the aluminum block holding the X-block. Raise your head to 50mm. Tighten the first screw from either side 3mm below the reference points. While maintaining the first screw, tighten the second screw and secure it with the first one. Slide the cache down to hide everything. Check your 0 coordinate and the position of the stopper. You'll no longer have to worry about forgetting to install your plate.
