By the way, the manual was too big for the list. Sorry for that!

Hello Hubert, and
I've recently started playing more with a 4th axis and have Fusion
spitting out some reasonably decent G93'd code.
Two things have come up now that I'm running a part or two.
1) Am I correct in assuming that the G64 P/q settings have limited/no
effect when using the a rotary axis and linear
Not sure that the sim.axis.gantry configs are going to be all that much help as
an example for most of that. Since the pertinent parts of hal code are
autogenerated with TCL files.

Have you looked at the supplied sim-axis-gantry config?

There is no need for complex maths. You can mirror a part simply by

What do you think? The price is more than good. The seller has good
feedback on all the listings but sadly, no enough sales to be sure.
I'm tempted to buy

yes, I use "Touch Off". the other one is typically grayed out. I am
pretty sure because there is no tool selected yet.
When I make parts, I typically use one tool per g-code, I try to keep it

There are two buttons "Touch Off" and "Tool Touch Off". You always use the same?

well, I am comfortable with matrix algebra, but it's probably easier,
more practical, to just do that part in freecad or so, and use a
separate g code file for that.
I was just wondering what these different coordinate systems are, what
they are used for.

IIRC some controls have a switch to do this. Also I think you can flip
the sign of one axis and get a mirror image but the sense of the cut
(climb/conventional) also flips so unless your machine is pretty tight
dimensions may also shift. I've always done this the hard way by going
back to the
Hello Andy,
That is interesting, I should learn more about these coordinate
systems. From a math/geometry perspective there nothing that could
keep you from
translating, rotating (and even more weird transformations) a geometry
into a custom one. However in an implementation, of course,
Jon,
I wrote a bunch of wizards for my mill and my lathe. I use one coordinate
system for the origin of the main part and a different origin for each each
wizard as it is called so that the wizard works with respect to the/an origin.
It makes the math in the wizard much simpler, especially

Yes, and there is also only rotation about the
