Sebastian,
Thanks. A couple more questions.
1 I assume I will have to build from source to use hostmot2?
2 On an m5i20, how do you use the general purpose I/O? I don't see, for
instance, the equivalents of:
addf m5i20.0.misc-update servo-thread 1
addf m5i20.0.digital-in-read servo-thread 1
addf

Mostly something like the arrangement Kirk Wallace has - software
stepping, using the GPIO for the step pulses. You might ask why do

Not true. Threads are interruptable, based on priority. Fast threads
are higher priority than slow ones, under the assumption that the code
in a 1mS thread might take 200uS to execute, and a 25uS thread might
need to interrupt it and run a few uS worth of code several times.
Sounds like
How valuable is it for hostmot2 to have stand-alone gpio access (for the PCI
cards only)? It seems like sort of a klunky interface.
The differentiating feature of hostmot2 is the flexible firmware, which solves
this problem very neatly. So I still think the current interface is the right

Hi
I am interesting in M19C(0-360) operation or spindle oriented stop. MAZAK
has that option because MAZAK should stop spindle oriented to tool changer
can taker tool out. I am interesting is any good setting of hardware –
motor with driver that can be used with EMC2 that will use M19C(0-360)
Tonight I hooked up the jogwheel and one of the motor's encoders (100 line
and 2500 lines) to the parport, and with turning up the ferror in the ini I
can use it like a DRO, turning the encoders moves the axis readings. I was
wondering if i could just build an H bridge or similar switching
