Bill,
While the Do While example in the manual does work, unless you changed
it, it's not very graphic. I have changed the example to give some feed
back if you test run the code. Within an hour or so the online docs
should have the improved example.

Well I have convinced myself that having a standby generator of
sufficient size to run the whole house is a good thing. I am now the
owner of a 15Kw 2cyl deutz diesel generator. It is a 12 wire generator
and at the moment it is set up for 208 120. After reading some on the
different wiring
Nice.
I have a Deutz engine on an air compressor. They are very reliable.
A 12 wire is the ultimate setup. Can't go wrong with that.
That engine should sip fuel.

Hi Guys;
I did notice yesterday while cutting that 4mmx0.7 thread, which btw came
out real nice, that the spindle speed you start at should not be changed
during the run as it will widen the cut thread, leaving a distorted profile
at the root of the thread. I had started it at an S200 and had
Would it be possible to write my own hal component that read the values from

If you dont mind writing some C code, I think you should extend halui to do it.
Read the values you want from the stat buffers and export them to hal pins.
See how halui reports the axis positions for an example.
These changes should go in the master branch, not in 2.5.

i did in fact end up using inverse time feed when my understanding of the
linear/rotational axes relations failed. that worked ok, but it was not a
satisfying closed form of solution to the problem in general.
in easier cases, abc is parallel to xyz. so you'd want to know the xyz position

How do we tell LinuxCNC / G-code where the rotation axes are in space?
Frequently
another fun translation problem: instead of x and y axes, you have a c1 axis
on top of a c2 axis with the two c axes separated by some given r. presumably
a spindle is centered the same r away from one of the c's so that a whole xy
area of 2r can be reached by rotations of the two c's.

I think mach has a place to tell what the 'radius' is of the rotary axis
so the feed rate is calculated based on that. (but they cannot do kins
and such) Inverse time really is the only way to go - that is what the
big boys use.

I dont think these ideas will work/produce sensible results
- Andy's idea conveys the readahead-time setting of #5220
- halui wont be able to report anything useful because the emctstatus message
doesnt contain that value (#5220)
the way I understand it all offsets (coordinate, tool, axis) are
Michael is absolutely correct about this:
...so Andy's scheme will report the last offset active, not the current one

In fact, any attempt to display the G5x offset, the spindle S command, or the

Hi John:
Thanks for the feedback!
I have found my mistake and all is working as should be.
Will look at ur new example, too.
