Re: Home Switch Setup Attention Fortino

Thank You Fortino,

Thanks for the reply to my question.
After I enter the setup you posted,....what actually do I do next to
confirm it's working correctly?

I only have home switches on the X and Y axis only, no limit
switches.
I have wired them independently or should they be wired in series to
one pin of parallel port?

That wiring diagrm was emailed to me from Doug Yeager, do you think
it would be better without the resistor?


Thanks
Shelby
