I have an add on card with two additional printer ports. On page 39 Master_User.pdf it says a full suite of home and limit switches can be implemented with independent wires, if 2 more parallel ports are added. if there are 5 inputs, for a three axis machine, does it make sense to have use 3 inputs for home switches and then combine the limit switches? Are the limit switches, useful for more than a safety feature for turning the motors off in case of a mishap? In EMC(1). are the pinouts customized by changing configuration files or is it more involved? djs Paul wrote: Hi Alex On Sunday 03 December 2006 21:18, alex wrote: I need to have 3 axes homed. Is it possible with present setup? Yes, you can have all three homed. Each axis will need to be homed separately and moved off the home switch before the next can be homed. If one axis is not fitted with a home switch, then the postition would need to be zero'd manually each time you power the system up as EMC wouldn't have a fixed reference point to work from.
