My personal opinion:
If You have double joints on all 3 linear axis, it might be easier to
modify a kinematics module, where You explicitly assign particular
joint to particular axis in forward/inverse kinematics calculations.
That is how my gantry setup is working.

if each of the axes is perfectly straight you will get a straight line even
if the axes are not ortogonal.

Assuming your W is precisely normal to the XY plane of motion, you would get
interpolation of a straight line. All axes would acceler

It would be much better to make the knee the W axis (auxiliary linear
axis parallel
to the Z axis). EMC2 has facilities to handle an
Eric,
Thanks for looking into it. I think i've figured it out.
SET_WAIT ON + SET JOG == crashing your machine.
It seems that when EMC is set to SET_WAIT on it stops listening for any other
commands until the given command completes. Since a jog doesn't complete, it
just goes until it crash

Yes! As long as you expect the right thing, heh.

Igor,
You have options with EMC2. You can use two different configuration files.
One configuration file to position the knee and use the quill as the Z axis
as Stephan suggests. Another configuration file to use the knee as the Z
axis and the quill as the W axis.
You can use the tool length com
Hello Igor,
For a way to add incremental moves take a look here...

I use the number 4 button with a joystick combination to make incremental
jog moves.

My Bridgeport Series II Interact 2 CNC mill has a Z axis in the quill.
http://igor.chudov.com/projects/Bridgeport-Series-II-Interact-2-CNC-Mill/
It has Z travel of only about 4.8 inches. Which is actually adequate
for most of what I do.
But, the other nice thing that it has is air assisted knee.
Hi Group!
I am trying to set up a 5 axis router with double servos on x,y and z.
I have a Mesa 3x20 with 3 7i33 servo cards.
I have looked at the example file 5axiskins that uses 9 joints xyzabcuvw,
but y2 seems to be linked to joint 7,u.
Can I make a variant of this with x1y1z1abcx2y2z2, or is
My question is about "rtai_shm.ko".
Im using Ubuntu10.04 from http://www.linuxcnc.org/mozmck/
When I tried to resolve some latency issues I found out that in "rtapi.conf"
is missing path for rtai_shm as you can see:
MODPATH_rtai_shm=
Is this correct or bug.

Hello Igor,
To make the joypad even more useful you can add incremental jog moves.
You can also add deadzones to the joystick to prevent accidentally moving
two axis at one time when you only want to move one.
By using button combinations to make moves, turn spindle on, etc. you add
safety to
