I've tried this as well with the same result.

If I change the limit switch polarities and start tkemc, the program
issues a dialog box telling me the limit is reached.

One thing I forgot to mention is the program updates the axis
positions as though everything is normal. The debug messages in the
console window also appear normal. I simply don't get any clock
pulses at the parport. I don't believe the direction pins change
either, but that could be related to the missing step clocks.
