Hi
I have a milling machine here which i want to control with emc. Fo the
first tests im using the "normal" parallel port adapter. I'm, however,
afraid of loosing steps on my stepping motors so im planing to use some
quadratur encoder to also measure the position of the axes. My questions
now are:

For "source code exploration" there are a few more things that it's nice
to be aware of:
* lxr web page, which allows you to see definition and use of any
identifier, http://cvs.linuxcnc.org/lxr
* tags, search for the definition of any identifier from vi or emacs
("make tags" target in src

The card implements the USB CDC class (it lookes like a serial card to
the operating system with the usbserial modul). So i thought since
serial connection can be used it would also be possible to use the USB
counterpart.

Gentlemen,
Thanks guys. Looks like I have some exploration to do.
thanks

Well, you could look at the hal_ppmc.

Dear All,
In 2005 the EMC gurus did a retrofit on a Mazak at the
CNC-workshop. The machine had a toolchanger. Was the
toolchanger controlled by Classic Ladder and if it was, is the .clp file
in one of the sample configurations of a standard EMC2
install? If it isn't, can someone

I am starting work on my mill setup, which uses Sanyo BLDC motors and
Rutex drives. The Rutex drives have SPI and step/direction inputs.
Without thinking too much about it, I brought up the standard stepper
configuration in Axis and before I tried to command a move, I grabbed
the motor shaft and tu
I was running EMC using BDI 4.49. Changed over to EMC2, Ubuntu 6.06. The mini
interface runs on the computer just fine, but the machine no longer
communicates with my stepper box on LPT1. Does anyone know what file contains
the I/O and pin settings for EMC2 on Ubuntu 6.06?

Aiken,
I am working on my thesis where I will talk about benefits of EMC2 and
step by step to build something that working.
I will include something about C programming next year but now working
around Abstract.
I am open for all suggestion critics and so on.
Thanks for any help.

I am puzzled by the issues raised of DMA and interrupts as a problem in using
USB.
In the WinXP system a common way of using USB connections is to handle it as a
'Virtual Comm Port' (VCP). When you plug in your USB device it is assigned a
Comm port number. After that the data link behaves exact
EMC does not use Linux device drivers for realtime control of motor
position. It uses special "real time" drivers. A specific real-time
driver must be written for each type of hardware interface.

I think that was part of the RT ethernet discussion, but I could be wrong :)

Gentlemen,
emc2-trunk/src/emc/kinematics/gantrykins.c
It looks to me like line 94 is incorrect:
is - char *coordinates = "XYZABC"
s/b - char *coordinates = "XYZABCUVW".
Is the 'is' correct or is the 's/b' correct?
thanks

If you did a fresh install, your EMC should be like mine. Parallel port
pin assignments are made in a .hal file that is referred to by an .ini
file. Look in your home directory under .../emc2/configs
(or /home/your_home/emc2/configs) for a directory that matches the name
of the configuration you tr
