Hi,
Has anyone considered the possibility of including load cells / strain
gauges into the control loop of EMC2? What I am considering is an idea
for making something which would require me to 'drill' a number of very
small holes in precise positions through synthetic sapphire sheet. I

I have Bobcad 21 and agree the stick fonts are ugly. Now if I can just get them
to stop calling me and wanting me to upgrade. Talk about high pressure sales.
I'm interested in getting the fix if it is not something that I can d/l from

If it's slightly off center, drilling the center hole will tend towards

I wanted to have a real motor/encoder system for my office EMC instead
of using a simulated configuration. So, ruined a surplus printer to get
the motor/encoder assembly, which I connected to an L298 and a +12 Volt
motor supply. When I got to testing it, I had a hard time with tuning.

After a fair amount of grief, I got dual screens working on my office

You need to use the Xinerama extension to X for multiple combined displays.
http://en.wikipedia.org/wiki/Xinerama

you can definitely restart X with `sudo killall X`
otherwise it looks like you have the right idea.

HI,
What actually controls the jogging speed? - I'm sure I knew but my brain
is in Estop just now When I start up Axis, the jogging speed sliders
are at ridiculously high values and, if I forget to change them then the
axes give up half way through a move losing my position. G0 works fine
I think it's this:
your.ini
[TRAJ]
...
DEFAULT_VELOCITY = 0.xxx

For me it seems to set the initial jog slider setting. Although, you
should not be able to jog beyond operational limits if your other
settings are correct.
Such as:
your.ini

...
MAX_VELOCITY = x.xxx
