Watching the video the tool chain moved while the gripper was over it. Is that

Not only is the material the cutter is made of but the type of cutter and the
speeds and feeds are most important. If you go a little too fast you can

That's an interesting idea. I wonder if you could modify a cd player to

I had thought about using a hard drive platter, a similar idea.

Sorry if I mislead anyone. Build the M5 into the gear change unless
you want to change gears on the fly.
OUCH!
Syntax for a gear change should be able to accommodate either an
explicit gear or a gear table. My thinking
leans toward a gear table that takes into account the torque curve o

Why are you considering moving to such a system?
Would the Tormach tool holders meet those requirements?

I have a flock of Tormach holders in a variety of sizes. Not only do I use
them in my Bridgeport, but they also happen to fit the turret of my little
Rivett lathe.

Hi,
I'm following this very interesting group for a while now. In the meantime I
build a plywood router and I played around with the hobbyCNC board connected to
an old laptop running EMC2.
I've two questions so far:

Geez, the resonance seems to be about 40 Hz, my sampling rate is
already 1 KHz, 25 X higher. But, yes, I can go to at least 5
KHz and see what happens.

I am losing patience with the Bandit on my Shizuoka mill, so I am
thinking of converting to EMC2 sooner than later. I would like to save
the stepper drivers but they look like they might have a proprietary
integration with the controller. The drives have four inputs that appear
to take in steps as

I've tried to get into IRC a few times with poor results. I think I just
