Hello!
Let's start with change of the topic - now it should be more appropriate.

Something else to consider ... you can make the PyVCP panel a stand
alone window. I believe there is a sample config that has that setup.

Many printers plotters do not use limit switches. Instead, they move the
print head slowly towards the end stop until the motor stalls, and then back
off from that point a certain distance and that's the home position or soft
limit.
What, roughly, do I need to do with EMC to get this behavior?

Nevertheless, when in that search mode, I think I would try to see if the
servo torque could be reduced to about 1/4 just for that mode.

I could maybe see monitoring following error... When the servo hit the
limit - the error would increase. You could then use some logic that
says when the following error reaches a certain amount - trip the
'virtual' limit switch. Maybe.. I could see lots of issues and as
gene says - you
Hi,
I'm trying to get EMC2 and Axis running on Debian Squeeze, but I ran
into some serious difficulties. Axis crashes on initialization of a GL
widget. I tried this on an x86_64 machine (rtai mode) and on PowerPC
(simulation). Both crashes with an X error.

And I would point out that those are 100% steppers, driving the carriage by

Dave,
do they use the optical strip transitions to time the firing of the ink
droplets, or is it only used to control the print head?

Well, I just figured out how to add an optical sensor without adding any
moving mass. This is the Y axis I'm working on, which is carried by the X
axis. If I home the X first, then I can use a fixed optical sensor to home
the Y axis. It would not be possible to home Y unless
