Our Mazak Lathe has a turret that uses a belville spring washers in a
friction brake. The nice thing about it is that when a collision occurs the
turret is pretty easy to get back on centerline. It uses a shot pin to
locate that is pulled back out when it is clamped. It is hydraulic
though.

On the two direction motion thing, Both Barrafaldi and Duplomatic will work in
both directionsI programmed mine to take the shortest route to the called
up tool..There is more to this than just rotating a tool into place. You
should be able to call up the tool like this.

Hi Glenn,
I also have a HP/Compag nw9440. Do you have Linux running on that laptop? If
yes, how?
I look forward to your reply.
Have a good day,

could it be fsb / memory and the like are the limiting factor, and not the
CPU speed? i've been curious how overclocking would affect the speeds
attainable. i've only ran emc on a slightly overclocked athlon XP
barton2500 system, i might have to get around to doing some more testing,
huh.

Kirk,
I believe this turret will only lock in one of the 8 tool positions
due to the internal mechanism. It probably has a Curvic Coupling to locate
it. The electric turrets in my experience and my situation (I have about 8
of these in my shop) are much more reliable than the hydraulic

Ian,
I am using the basic output from HAL via a 1284 parallel printer port,
(mode 2). The stepper motor drivers are just doing the chopping to limit
current. I didn't change HAL in any way.
The one thing you might try is to limit the acceleration.
I was surprised when I raised the motor voltag

thing.
I am trying to figure out generally how they work. Does anyone have

Thanks Jim,
I then switched to a simple chopping driver with no
micro-steps, and let HAL do the work. HAL was
capable of driving steps well up into the 50 microsecond range. >>
