Taming the @#$@ Z-Axis Stop...

thingiverse

In my Replicator, multiple collisions with the Z-axis stop led to misalignment of the build plate. The issue was traced back to the switch being held by its mounting lugs in a precarious position. Whenever the carriage missed the switch, the motor kept driving the stage upward, bending the switch along with it. To repair this, I had to mend the stop switch. Removing the switch seemed simple but reassembling it proved challenging, especially given my less-than-ideal finger dexterity and vision. Two hours into trying to thread nuts, spacers, and circuit boards, I decided to bypass the Z-axis motor removal step. Without a functional Z-axis stop in place, I managed to complete another project and promised to share my experience with pictures. The project utilized 0.080 sheet styrene, known for its friendly workability, similar to model kits. It can be carved like wood, doesn't shatter when drilled, and bonds beautifully with PLA using slurry. My new Z-axis stop design incorporates trapped nuts and slide-in mounting ease for convenience. The photos should provide a clear demonstration of the process. Perhaps someone could create an STL file for this design. In its installed state, only the box holding the switch is attached to the Replicator's case. The switch is retained by the box and can be easily slid in or out when needed. Tightening down the mounting screws entraps the switch, preventing movement. No more hassle with bolts, nuts, or spacers! Lastly, don't forget to upload an STL file for publication. In lieu of a relevant one, I've included a bonus file for an oriental cuisine recipe... albeit another nonsense addition.
