Limit switch settings

[Stevie]

Hi Guys
First off I love Turbocnc; simple yet smooth and powerfull
Next a question

I have my home's set; works great; chk'ed with a DTI; bang on every time to the pre set distances
I wanted to set 2 limits; max distance for each axis; now this is where the trouble started; I can't seem to set a limit Turbocnc see's; so as a last resort; I set the panic stop imput to act as the limit's for now
I just made all the switches go to the same pin input on the LPT1 (pin10 active pulled low)
I had pins 10 and 11 set as limits; with 12 and 13 as homes; all set active pulled low
The multimeter see's the pin pulled low; but Turbocnc will not
The built in key chk is set to default to port 0278 (or what ever) mine is set to 0378; how do you change it in the Keychk utility?

Any suggestions ???????????????????????
