Anycubic I3 Mega S Z Stop Problem Solution

thingiverse

Anycubic I3 Mega S Z Stop uses a 2.5mm locknut to interact with z stop micro switch. The lack of a sufficient planer surface to interact with micro switch actuation lever causes extreme variation in Z homing resulting in damage to a great work bed surface. This simple solution solves the problem. I have supplied 2 configurations of varying tightness in threads. Although the 100 will more easily start to thread onto the screw, forcing the 90 to thread onto the screw will result in a nice tight fit not requiring a lock nut to keep it from accidently turning. Any version used should be pre fitted to the screw out of the machine preferably with a power driver to improve the printed threads. Use the supplied lock nut for adjusting the spring and use the supplied spring tension nut as a lock nut against the printed Z Stop Nut if at all. Cheers! Note: WaGi-3D Has a nice insert to secure the top of the Z Stop Screw and keep it from wobbling. I just downloaded it myself and will be using it as it also addresses part of the cause of this problem. I would estimate my part is a 99% solution and with the addition of his part well, "Damn!"
