Best way to get accurate and timely help on a problem is to post a good description of the problem and include all of your config files. RRF is configured with gcode, so showing what gcode you are using is critical to helping others understand what's actually happening with the printer.
@Touchthebitum@sko if you want some more help getting your z offset correct, start new threads and include your files. It's usually a fairly simple fix to methodology.
Also, these non-contact AC voltage probes can be a real lifesaver! They’re not too expensive and really great to keep around whenever you’re dealing with mains wiring. Just wave the tip by each of your wires before going in to make sure they’re not powered.
