Did you fit a limit switch to each end of your axis? Ie one limit at the end of + x axis and another at the end of - x axis and the same for the Y and C axes and also an e stop switch at the end of each axis? I am trying to get the idea of how the switching is designed to work. I am used to seeing an end limit switch and an e stop switch at the end of travel for each axis. Obviously the CPU4 card does not have the connections for this type of wiring so is the best idea to fit a home limit at say the + end of travel for each axis and connect them all up to the home connector, then I was thinking about fitting an e stop switch at both ends of travel for each axis and dasiy chain them to the e stop connector seeing as the card does not have seperate inputs for each axis for an e stop signal.
