"New kid on the block"

Hi there !

I have been listening in for some time now, - and I have some
questions.

1.

I used Autocad under dos, and I now have two tablets:

- CALCOMP 2200
- GRAPTECH Digitizer KD4300
How do I hook up these ? Does anyone have manuals for these ? Do
you need any special drivers to run them ?

2.

I am using Linux, - and I just hate the "microsoft-box" ! I am just
sorry I didn't switched to unix or linux - years ago. But I admit,
- it can be difficult sometime. I have used 6 months to get the EMC
working ! I used a 486, and I recall that someone said they wanted
to set up a 486 in their workshop. There is some files that needs
to be modified to get it working with the RT kernel, because it uses
shared memory a little differently:
- in lilo.conf : append="mem=xxx" - set aside less than 1M
- in /usr/src/linux/include/asm-i386/param.h - change #define
EXEC_PAGESIZE 4096 to

#define EXEC_PAGESIZE 1024
- then the good guys at NIST has done corrections in the
emc-06-Jul-1999.tgz

I just wanted to pass this along.

3.

Does anyone know where to change the xemc, so that it opens in a
window that is not larger than my screen ? ( I can't use a higher
resolution - I need to change the window size )

4.

Does anyone have a script that strips off all the quotes from the
digests I receive. I use a lot of paper to print out the same info
again and again.

5.

I want to use the EMC software to run servo motors, not steppers.
Is there anyone who has some schematics on servo amps ? I would
like to make my own.
There is also some problems, because my motors don't have any tacho
generators. To get tighter servo loop, you need that. Does anyone
have an idea how to make a tacho signal from the encoders ?
I know about a chip that does this, but it will only work for sinus
shaped encoder signals
( SGS L291) - any ideas ?

6.

What is a DRO ? - I guess it is a Digital Read Out device, - but
what is EDM ?

7.

Someplace I read that some wanted to divide this list. Not everyone
is interested in ball screws etc., I understand that. But what if
there were a DIGEST made over people that uses this location, with
information about what and how many uses Linux, EMC, skills,
interests, etc. Then you could post a question to those who most
likely would know what you would like to know, instead of having
everybody answer the same question. Sure all comments would be ok,
but I guess there is someone that seldom speaks up, - and they may
have some very interesting projects going on, - something others
would like to join in on. Just a thought.

8.

Someone mentioned a laser scanner for 3d. Does anyone know what
kind of principle they use to do this ? ( I know of several
possible solutions - but would like to get some info on how they do
it )



Best regards
