Y Limit Switch Problems / Lots of Grinding Noises

Recommended Posts

So this started with Lift Switch Issues and I think I ended up just finding a stop gap solution for that, but now I'm having more problems.

 

Here's where things started: 

 

 

So now when I try to print, or seemingly randomly when it sends itself home, I'm getting LOTS of grinding noises once it gets to the corner and occassionally the printer faults to ultimaker.com/ER17 and my only option is turn power cycle the printer. I've tried everything on that page (both switches make the clicking sound, I can press either switch during the "home" action and it will no longer travel in the associated direction). The two things that I have done that aren't normal, are in the Limit Switch Test, I can't get the Y box to ever be checked. I previously got around this by offsetting Y by 0.4 to fix the Lift Switch problem (which is still set to 0.4 and it's the only way I can get the lift switch to raise and lower properly), but the box never checked in the Test, even after the offset.

 

in the previous thread, both "end stops" and "set screws" were mentioned and I'm not sure how to look at either one. I briefly looked at the end of the workday today and the only screws I think I see on the axis rods are literally ON the rod, not on the end, but rotating around the side as the axis moves, but near the gear on each end. Is this what I'm supposed to tighten? I didn't have a bit that was small enough, but should be able to find one tomorrow. 

 

Let me know if there's any information I left out and thank you for any help you can provide!

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
