wow, thanks for clearing those things up for me. I only see active lows in the mach3 inputs.
When i have the active lows checked, the diagnostics screen shows everything normal. But when they are unchecked the diagnostic screen shows 3 of the homes lit up. I dont have anything hooked up yet though. I'm sure ill figure it out when i get it all wired up. I already have the swtiches mounted so they click when they dial goes to 0.
