I’d maybe double check that that is wired NO. Unless you have some funky switches, that looks NC. The default set up Inventables lays out is NO switches, which I’m not a big fan of since I crushed a switch due to my connection at the G-Shield coming loose!
That being said NC switch, I feel, would be the best choice in terms of safe guards. We discussed shielding HERE as apparently NC switches are more susceptible to noise.
You also have to change some grbl settings to make the switches work in the NC configuration. Sorry if you already know all this, I’m still sorting this all out and find it helps my understanding the more a talk about it! Good luck with the rest of your build!
