I have just bought a pci to lpt card. I intended to insert more I/O ports
for emc2. But I could not install the card in Ubuntu 6.06. I did as the

was trying. - like it is hard for me to tell if they are getting warm at
20a.) The inital mosfets I was using had a Rds that was way to high.

I found maybe an answer to the indexing problem I am having
These lines are in the m5i20_motion.hal file:
# Connect index enables to motion controller, for homing.
net Xindex-enable m5i20.0.enc-00-index-enable <=> axis.0.index-enable

Some-one was wanting to build a large format milling machine a few months
