I found a workaround; It's possible to read HAL pins from g-code. The
problem is they don't necessarily update after the program is started. But
according to the manual, a state sync command--M66E0L0-- forces it to
update. The problem is that this stops the motion, and now instead of a

I just ran the following gcode:

Generally speaking, usually R breaks at 180° where IJK can do a full 360°
arc with a single command. I think it's possible to go >180 with a negative
R, but I'm not sure where that ends. I've never been a fan of R because it
tends to break tangency where ijk are a little more strict.

I believe that R arcs that are 90 degrees or less are going to come out
very close to the IJK versions, but if you want a full circle, it's
better to break it up into 4 90 degree arcs. I don't know just where
radius arcs start to diverge from IJK arcs, but I would guess that 180

I have found that the "Magic Pixie Dust" for a damp shop comes in a
spray can called Caig deoxit. The trick is pairing a contact cleaning
solution with an appropriate oil that seals the contacts so that oxygen
can't get into the connection.

One option would be to generate one big G-code file, with the
appropriate M-CODE to break it up, and an operator's comment to let you
know which section is coming up next.

Non-trivial kinematics is when moving one axis causes another axis to
move. We call these "serial links"
For example, if you were to mount one rotary axis "B" cross-wise on another
rotary axis "A" such that moving "A" redefines where "B" is pointing to.
This is common with robots but uncommon wi

I had looked at a cnc nibbler and scrollsaw.
I thought it might be nice if Axis could show the tool orientation.
So I made a tiny hack in glcanon.py and minigl.c
What I did was modify the disk on top of the cone, and the disks on top
and bottom of round tools.
I simply enabled and used the g

If it is a rotary axis with an axis along Y then it is typically called "B".

Probably not. It sounds like
Perhaps I misunderstand but why do you plan to cut the thread in short
pieces rather than the whole length but obviously in several passes due to
allowed DoC and WoC? Is the final thread diameter to be about 2-inch or much
smaller? In any case shouldn't you make the stock approximately round prior
Greetings all;
I am about to install this rebuilt rotary drive on my 6040 mill, aligned
to rotate stuff on the Y axis, which is the long axis on a 6040.
Out of the alphabet of ABCUVW, which is the proper axis to call it?
It will for the next job, be turning a 2"x2"x18" on center of its 2x2

I will look into the halsampler solution. Can you point me to a working
example? The end goal is indeed a point cloud.

True, though there is something to be said for having a dummy axis
just so that the LinuxCNC GUI will display the encoder position.
