Is it all down to one person to "approve" changes??
How about the jog during M6 fix that Les wrot
cradek is the release manager for 2.5 so before adding anything to 2.5
I check with the release manager to make sure there is no conflicts or
problems.
I'm testing it out now... for 2.5

I am adding 5000 count Heidenhain rotary encoders to the servo motors on my
mill.
The conduit that goes from the servo motor to the control box that holds the
power and tach wiring, can I run the encoder wiring in that conduit.
Would the power or tach wiring interfere with the encoder in anyway?
I wouldn't run encoder wiring in the same conduit as power wiring. Most
encoder wiring is at a 0 to 5 volt level, and could easily pick up noise from
the power or tach wiring which could mean extra or mixed counts. I would also
have the tach wiring and encoder wiring run with shielded cable,

I belong to that group, there is some interesting information there. I was
under the impression that during WWII using concrete in casting large machine
parts was used because of lack of raw materials, and fairly common. I've always
thought it would be fun to experiment with this technique, not
is there a way to make the g28 command seek the home switches rather than a
predetermined coordinate position?

It was Lucien I. Yoeman that patented this back during WW1, not WW2,
for shell turning.

Concrete is fine for compression loads. You can mix 5000 psi concrete
pretty easily. However it has very poor tensile strength. They say
10-15% of the compressive strength. Fiberglass has a much higher
tensile strength.
That is why concrete has to be pre-stressed to be used for tensile
app
