I personally would like to see it stay on this list. I liked what I
saw of your program while at NAMES, I will be home by the end of
this week, and hope to get some good time in the shop playing with
the CPNP program then. I lucked into some ball end mills, so have
figured out what I need to do to the Sherline Mill for my first
conversion. bill

yes, stay here
I'm in for some programming too, I'm working now in Delphi, but I'll
be downloading the tcl stuff and will learn it for the purposes
if needed.... I'll be building a small mill in the next six months so
will have a testbed too. That will mainly run Linux/EMC, but the
machine will have removable harddrives so I can swap it to Win95 if
needed.

I have an option on some small servo motors with encoders. just two
though. is it possible to run EMC with 2 servos and one stepper?

Re: PROJECTS STILL ON THE BURNER?

It now appears I can get my Beast (the 1984 Leadwell-Ramco) of a milling
machine to accept drip-feed input through its RS-232 port. I tracked down
the people who made the old Centurion IV control (they are called
Milltronics now, and are located in the Minneapolis area) , called the
number (952-442-1410) and talked to "the old guy in the back". He assured
me that if I could be happy with a 1200 baud rate, could come up with some
kind of "BTR" (Behind The Reader?) box and appropriate shielded cables, and
found a control program that could output my G-code as step and direction
through the serial port of my computer, using Microsoft's built-in
Hyperterminal or some other null modem connection, then I'd be in biz- able
to feed it unlimited-size files in DNC mode.

This sounds distinctly doable (much more so than the Brain Transplant), but
I've got some questions for the experts here:

What control program should I use to communicate with this old DC
servo-equipped mill? Is this a good excuse to try CNC Pro, or would
something else be better? Is the DOS port of EMC really ready and for sale
someplace? I think this would go fast enough on my P223, in DOS mode-
wouldn't the low baud rate be the limiting factor? How many inches per min.
should I expect, in contouring mode?
Do I really need some special BTR box, or can I go direct from the 9-pin
serial port of my computer? Does this machine need its code fed in some
special way, which the BTR translates from standard step-and-direction? If
I do need one, which is the most cost-effective (for an non-electronician)?
What about the "software handshaking" it uses: x-on x-off? How does that
work? Is this just a series of characters I need to insert at the beginning
of each program, (and if so, how do I find out what they are?) . I was
thinking of Predator cables- anybody had any experiences with them?
Predator also had a $700 control program (with cut previewing and other
nice features) - anybody tried it?

I'm sure I'll have more questions as I go along...
