I have a couple chinese lasers using RDworks as the software. All the sudden autofocus stopped working on both of them and the tip just runs into the substrate if you try to auto focus and doesn't stop trying to go down until you hit reset. It looks like an employee changed something but I don't know what since they both started doing this at the same time it's clearly not hardware related.

Anyone know what settings cause this in RDworks? Is it something on the testing tab (tab with the autofocus button) or something else they messed with in RDworks?
