Didn't try this from within AXIS, I'm using the command line. The chmod
is to set the flags (x) to let the operating system know this is an
executable.
If it works from within axis, the better.

For slow I/O like coolant, a device attached to a serial or USB port
can be appropriate in emc2. You'll probably have to write your pic
firmware and an emc2 hal driver in tandem, since there's not an
established protocol for this (unlike, say, stepdirection signals).
Conceptually, the PC side is
Hi Dave,
I'm sure someone will correct me if I'm wrong; so here goes.
The way index homing works is that after the homing switch actuation is
detected, the next index pulse sets the home position. If, by bad luck,
the edge of the index pulse is right at the switch edge, a little jitter

because each motor has its own encoder. Is it than possible to use two axis,
to control same joint?

Hello,
has somebody allready written a hal driver for a serial IO interface? Till now
I use a serial interface with a pic and 32/16 In-Outputs with Emc1 and tclsh.
A nice example in C would also be helpfull. Is there anywhere an example for
a c driver in user mode(not realtime) ?
Thanks

Hi all,
Finally found a 'roundtoit'.
As a quick test of homing repeatability I mounted a piece of 6061-

move from homing position to the workpiece and then drill a 1/2 hole
using a 0.500 carbide endmill.

Rather than writing another serial interface why not use Modbus and a

The Modbus protocol is extremely robust and has a number of saftey
features built in.

John,
Progress made. I installed QCAD as instructed. When I run
ENGRAVE-11.py through the browser screen
(outside of AXIS) I no longer have the red file path error. I can change
the text, see it reflected in the cross hairs.
Of course the Recalculate button up dates the screen.
John,
I got into QCAD by typing QCAD in the terminal prompt. Who
says you can teach a old dog new tricks?
