Hi Bill,
The first step (before trying to do anything in Mach3) is to write some C code to home each of your axis and verify it works properly from the KMotion C Programs Screen. See the SimpleHome.c example for the most simple example.
To then reverse direction, stop after the switch changes again, then Zero the Machine coordinates, you might do as shown below.
After it is working you can then merge the code for each of your axis into the corresponding place in the HomeMach3.c example.
Regards
TK
#include "KMotionDef.h"
#define X 0 // define X as axis 0
#define HOMEBIT 138
main()
{
Jog(X,-1000); // start moving negative
while (!ReadBit(HOMEBIT)) ; // wait for switch (input #138) to be high
Jog(X,100); // reverse motion and go slower
while (ReadBit(HOMEBIT)) ; // wait for switch (input #138) to be low
Jog(X,0); // Start Stopping
while (!CheckDone(X));
// wait till stopped
Zero(X); // Zero the Destination
}

ya I was using that jog command in the other code but didn't get to the point to look in the manual what speed it would jog. Or in other words, I was curious about the command that didn't seem to have a parameter for how fast to move.

Can anyone point me to some axis home code which works in Mach? Was playing with some code but pressing the ref all home button does not seem to start movement or anything. So perhaps some other way to trigger it? .. Basicly just want it to work like my mach parallel port machine where it joggs slow hits the micro switch which opens I think IO bit 138 could be wrong) then backs off untill the circuit is closed again. Then repeats for the other 3 axis.

Yes the second parameter in the Jog() call is the speed in counts or steps per second.
