I have the master, as of a couple weeks ago, but I don't see any of the hm2
stuff.

I have also been mulling over the ft232h. I asked ftdi, but never received
a reply, about the latency. I assume it is at least 125 usec, but that
depends how that everything is managed. If the usb host stack could be
hacked to give extra care to a specific device, it seems it could work,
althoug
seems like only things that start with hal_ or rtapi_ get built and
added to the html from that directory. I assume it is a submakefile
thing. None of the man pages are directly included in the PDF docs.

Well, the docs do exist, but don't seem to be linked to the PDF or
HT
My current spindle is very low tech, a bosch colt. I would use a 4-20ma
amp donut, perhaps wind a couple extra loops.
I'll have to think this over a bit. It is one thing to write a driver when
you have complete docs, yet another when you have to search so many places
for all the information.

It all depends on the RPM. 1000 count/rev encoders would be fine with
software conting

Does your spindle drive provide an overcurrent signal? If it is a
contact that opens on
fault, you can just wire

The mesa card looks interesting to me. The catch is, how is one going to
go about doing spi and pulling the data into emc2? I assume everything
would have to be bit banged, and is not taken care of in the fpga. It also
says it has quadrature encoder interface, but once again, how is this
handled

In reference to my reply, I suggested that using the parall
ight be able to jury rig a simple temperature controller to
read the analog and switch a relay output.
Look up RS part; 719-1093

I am not so sure about the parallel port and encoder idea though, the
encoders I see are up to 1000 per rev, that requires a pretty fast base
period to handle that, not? <2us ?
I also am not very clear on emc2 capability to manage analog inputs, it
seems easier to offload the deciding to an exter
I don't care about an analog measurement, I want the system to pause or
park when amps are outside of a set range. How would you do the first
scenario?

You just want an overcurrent limit, or you want an analog measurement

I am doing a bit of 3 axis cnc routing on pvc. I would like to set it and
forget it while it runs. I have been thinking about building, or buying if
available, something down this line.
Parallel breakout for stepper drive.
Microchip pic32 or similar to monitor incoming steps
