Nevertheless, Sven, it would helpful to know details about your
computer---motherboard, bios version, cpu, ram, etc. Like Michael said,
I do not see yet how an OS version change should make much difference
here.

I'm doing a LinuxCNC conversion of a huge CNC saw and dual gantry
router. I call it The Beast. It's a gantry machine with a 7.5 HP
radial arm saw, two 15 HP routers, and two air drills. It's made the
enclosures for some of the finest loudspeakers ever built, and needs to
do so again.

I think part of the problem I'm having might be caused by not using the
Hall Effect sensors. The old Siemens motor uses 15V Hall Effect sensors
and the Ultra3000 wants them to be modern 5V Hall Effect sensors, so
Voltage translation of the 24V hall sensor outputs to 5V would be straight
forward. Inside the Ultra the hall sensor inputs are pulled up to 5V by
1K and also the input goes through 1K to the input of a 74HCT14. There are
clamp diodes at the 74HCT and a small cap.
