A few pics of the limit switches. They're pretty much all toast and I would like to replace them. This one looks to still be functional, although, when I pulled it out to clean around it, i found that thin curved spring bit laying inside the housing. I put it back on but no idea if I git it right way 'round. My control errors out now, telling me the limits have been hit and to move off of them. No idea if these are NO or NC switches and not sure if I have to shut down the control to remove the error or simply push the gantry off the switch.
Here it is with the spring off:
And here with the spring on. It could go on with the curve the other way as well. Neither configuration got rid of the error yet so I'm thinking it's something else or a combination of things.
