Has anyone seen this type of stuff before? Running V Carve Pro with UGS to Spark Concepts XPro V3. I'm using a Triquetra 3 axis touch plate. I get these messages when I try to run a 3 axis zero or just Z only. Keep in mind that I've had problems with the XPro since day one (Nov 2018). No homing cycle can be ran & the switches don't respond when manually tripped within the Openbuilds controller program. Spark has been totally worthless in helping due to ZERO response from them. Maybe someone here can "bump" them again for me?
How have you wired the switches? Normally open or normally closed? Lets see your grbl settings as well.
