Ultimaker Original won't recognize front right switch

[delawarelibraries 0]

I am trying to calibrate an Ultimaker Original for my public library. At first, the extrusion head moved to the front right and made horrible shuddering sound. Would not continue.

Now the software won't recognize front right switch during first run wizard.

Any suggestions?

Thanks,

Sarena

Double check that the connections on the limit switches are correct.

I had mixed the front left switch on my first install, and that exact thing happened, just kept slamming into the left in horrible grinding noises.
