You can do JTAG by bit-flipping the parallel port. There is
TEST_MODE_SELECT,
TEST_CLOCK, TEST_DATA_IN and TEST_DATA_OUT. So you need to drive
3 signals and sense one. You probably need level translators for the

I would like to know if there is something for Linux that could
control heat treating ovens, like this one.

Hi,
The emc on documentation

shows
G81 X- Y- Z- A- B- C- R- L-
which to me indicates that it should work given C axis values. Is this
correct?

Are there Linux tools? I found:

in a terminal try:
locate trivkins
to see where it is
you can find a lot of stuff using 'locate'

Hello all,
One of the machines I run EMC2 on is a Dell Optiplex GX520 using a Pent 4 CPU
3.00. Some time ago I installed the Live CD with 8.04. I made some adjustments
(such as smi) and it tested at around Servo 10,500 and Base 11,000 which are
fine for what I am doing. When I test 10.04 I get
I knew they had to be together in one place. Thanks Jon, now the work
begins!

As far as micro's go, if you're talking about a low cost entry point, then
here's another option;

It can be done, but might take a bit of fiddling.

Have you discounted the Arduino? That is effectively all of the above,

Hi everyone,
I have changed the tool holding on my emc driven rose engine (see
http://blog.alanbattersby.co.uk/wp-content/uploads/2010/10/img_0038-rose-2.jpg)
so that the tool depth direction can be set at a variable angle and not
just perpendicular to the other two axes.
So can I show this or
