Hello All,

I just installed an ethernet smoothstepper card (upgrade) and have homing issues. I start the homing process and the Z axis moves, make the switch reverses direction, and then won't stop.. I did have this problem before. Upgraded from a parallel port running Mach3 and it had been working fine.

Using 5v running to 4.7k pull up resistors on pins 10,11,12,13.
Limits on 10 are normally closed and all in series.
Home on 11,12,13 are individual and also normally closed.
My port monitor shows my active high when I finger the switches on all.
So my limits work fine, but Mach3 wont flash a home signal when voltage goes high on 11,12,13.

Any suggestions?

Mike
