After having this issue, I have sent a message to S3D And am posting it here in case someone else has the issue.

Hardware: Folgertech FT-5

Problem: I click Home X, Home Y, and then Home Z
Home Z Button gives the error "Z probe out. bed"

=================================

I do NOT have a bed leveling probe and did not change any code that caused it to get this error. The Home Z button hasn't ever worked for me on its own.

Purpose: I have a failed print I want to restart at the level it failed at. I have it ready to do so, but I cannot home the Z Axis because using the "Home All" button centers the tool head in X and Y over the existing section of printed model (with no way to make it stop doing this) and the "Home Z" button does not work due to the above error.
