usually means there is a problem with how you set up [TRAJ] COORDINATES, and
[AXIS_*] sections.
You probably need to have AXES = 4 (to cover X,Y,Z,A), but coordi

I'm trying to set up a computer for a customer who wants to just run a
single rotary axis with EMC.
He's using my PWM board and one servo amp. I was trying to strip down a
4-axis configuration to
just run the one axis. So far, I have built a complete one-axis and a
two-axis set of configs file
More about lathe diameter mode on the Fanuc 0-TC (I found the
manual):
In diameter mode:
X specifies a diameter
U specifies an incremental diameter (not relevant in EMC)
coordinate system setting is done in diameter (like our
G10L2 and G92?)
X tool offsets can be in radius
Isn't the math:
I(relative) = I(absolute) - X(start)
J(relative)=J(absolute)-Y(start) ?

Hello Carl
Your math's is right (I think so)
However your assertion in my ability or inclination to write a script or
program, sorry wrong.

If you are machining an arc in the X-Z plane and the X has been scaled
to half it's true value then the arc will come out squashed.

The GUI also needs to know about this. Presumably there is a way of
notifying the GUI if a Gxx is issued to change between radius and
diameter. Does anyone know if any other control uses a suitable G-code
for this?

While I'm no 7i43 expert, I appear to be part of the small group of those

Jon,
The mill is larger than a Bridgeport. Its a 7,000# Tree Journeyman 300 with a
12X26X6 envelope and a 500# part capacity. The motors, reduction (about 2.5:1),
ball screws and encoder counts were not changed in the conversion to Mach3. The
original amps, servo dynamics, were rated for 20 amps co

Richard,
I'm a happy and satisfied Mesanet customer.
I use a 5i20, 7i33 and 7i37. with the 'stock' and 'proven' EMC2
configurations.
I have stayed away from the 7i43 until the EMC2 driver and configurations
are thoroughly worked out.

The okuma lathe I used had a g code to switch to mirror image.
After that, the spindle direction was inversed,

Hi Kirk,
Yes, basically you reflect the X axis about the origin. The only problem
is that this has to be done in your current coordinate system, before
the tool offset is applied. If I understand your solution correctly it
would change the machine coordinates. X=0 in machine coordinates will

Basically gang tooling. The rear tool post is mounted on the rear of the
