I just posted a blog entry on how I configured EMC2 for my three stepper
CNC machine. OK, it's the most basic configuration, and I picked a
specific situation (200 steps per rev motors, 1/4 microstepping), but I
hope it will be useful to someone else as a starting point.
I am very impatient, I admit it. But I sent a message 2 hours ago and I
still don't see it on the list. Since I haven't posted a lot of message here
I am unfamiliar with the delay. Am I just a bit unlucky today?

Does anybody use or know whether EMC will work (without headaches or
major customization) with the following CNC Masters Kit:

Any help or feedback will be much appreciated.

* Requesting a higher step rate than can be delivered at the given

* Not specifying the required headroom for stepgen's maxvel and

The override limits check box is when you are stitting on a limit switch and
you need
to jog off of the limit switch. That is the only time that works. Do you have

Hi Colin,
that would be me.. Can you reproduce the problem on a i386 install?
(I assume you are the one that posted on cnczone).
The proper fix would be to use a newer RTAI version, I have one already
built for i386, not yet for amd64.
It would be great if you could verify that with this version

Yes.. After I added the read funtction to the servo thread. Locked up
almost instantly this time... had enough time to open a halmeter and
pick the pci8255.0.1.a0 pin. As I was fumbling to set the pin high..
it locked up. This is running trunk.

We run into a problem on a 3 axis mill.
We understand that the default mode for EMC2 is G64. (I think this is not a
very good practice, especially for mills.)
Our problem is that we cannot switch from that mode.
We tried to put the G61 or G61.1 command into the lines.
A video, that shows the
Since the theoretical path and the actual movement significantly differs

A machine (in my oppinion) would have a home switch (where it would home
consistently). Starting from that position you have software limits (you
are allowed to travel up to the soft limits, and never beyond).
Outside of the soft limits bounds, you have the hardware limits. Usually
these are wired

No, I'm saying that check box is only for when you have tripped a limit switch
not for
soft limits... AFAIK... fires up my emc2 machine to see if I can figure out
what you
are doing... AFAIK you can't run a program that will exceed your soft limits...
Is your

Even if you fire up the machine at the extreme of travel you still home it
first which
sets the home positions. Then you have no problem.

Hi
I think that MESA Electronics should be interesting in developing software
part for EMC2 build on 5i20, 7i33 and 7i37 boards, to plug and use MPG4
pendant.
That will promote sale of 5i20, 7i33, 7i37 boards.

Hello,
I guess I'm using the wrong terminology. I'm calling hard limit the
table running
up against the frame.
I've also noticed that soft limits (in some cases) don't come into play.
Maybe it only
comes into play after the first *home* setting or after the first
program is run.
