well - it could do the velocity.. but the acceleration is set pretty
safe (not too many spare parts.) iirc 10in/sec^2 or something like that.

Sam,
Hi
I have a lathe that does just one job all of the time (one part with
varied sizes). The trick with this lathe is that is is two lathes in
one. A mirrored setup with a dual tool post in the middle and a spindle
on both ends. The tools are fixed always. It will cut one side finished
and then

A picture would help a lot.
Do you want to use XZ for both spindles, or would

Can you rotate like you show and then mirror X?

That depends on how many lumps still hang together on my coat. It has
some signs of wear and tear.

You can with G10 L2 R180. X will rotate 180 deg around the Z. Not what I
want. I need to rotate the Z.

How about just ignore conventions and invert the Z direction.

You mean like with a component to invert the dir pin of the stepper?

Maybe I should have mentioned that only one spindle is active at any
time. So in essence we have two lathes in one in order for them to step
up production. They share a tool post and the x axis. Well the Z as well
I suppose.

I am not sure of your setup one Z or two, if two yes just have your Zs
in the way that makes the gcode sensible, so one is inverted, I think
your display may need fixing too so it looks properly right hand.

I think you have given my some idea of how to approach this. I will have
a panel with some controls on and a python script behind that to make
sure only one chuck is working at any time. This way I can turn the
setup around and still have the same gcode to work on both sides. One at
a time.
This might be doable with a programmed tool-change position at the
cross over point between the two Z axes.
(There is an INI file entry for that)
Basically the toolpost moves to zero in the absolute coordinates, then
a bit of HAL code inverts the scale of the Z stepgen or PID (possibly

Why would one have a mirrored lathe if only one is usable at a time?
not sure I see the production gain.

Load one chuck while the other is running.
Which of course raises plenty of safety concerns. I hope Marius
has a plan for that -

Unfortunately, the new TP still has the restriction that you have to touch
each segment at least once. A small NCD tolerance is still useful to
combine stupidly short segments, in

That was my first concern as well but as I am not the designer or
builder of the machine I have no say about that. The owner did ensure me
that there are screens to be installed that will shelter the operator.
People do funny things and I just install and configure LCNC :)
