But can you shed some light on setting limit and home switches? I eyeballed hardware section of the manual for some time and it looks like they are hardwired for this version of EMC ? Are they wired this way: homes - pin 12 limits + -pin 15 limits - - pin 13 ? Also , how can I ignore homing for Z axis?
The home and limit switches are hard coded in to the sources. For many users, this limitation is not a problem, but for others, it is, so there is work afoot to address this and other issues (more on that when the time comes).
As for ignoring the homing on a single axis - If the axis with the home switches use HOME_SWITCH_POLARITY=0, set HOME_SWITCH_POLARITY=1 for the axis without a switch - As long as pin 12 is pulled high when X and Y are not sitting on their respective switches, Z will always be evaluated as "homed". Set the HOME and HOME_OFFSET parameters so that the homed axis does not sit on a switch and you shouldn't have any problems.
Regards, Paul.
