Thanks. Yes I did isolate logic and power cablesit looks much neater but
did not seem to make any
difference to the results

Hi Aaron,
I've recently been messing about with microstepping drivers trying to
get precise rotation and some speed out of a little lathe head. I found
that microstepping gave me all sorts of problems and that, at 1/8 steps
- the limit of the drive I had, the highest possible speed was much

Yes, and I can also run cvs to do anon checkouts from other systems. Log on

to change FO

I don't think so. I bought a single-row 1/4 thread mill

No you can't. ?Sourceforge disallows it. ?You must not have actually

Oh shucks - Must have been another machine I was logged
There is an example here

while not an exact example of what you want it should get you close. Any when

work out the details please add it to the wiki page

Hi
I thing we uncovered all potential problem for slow speed machine.
Here a will use more refined numbers and it looks more close to real
situation.
Minimum counts to controller about 30 pulses per second.
Or 1800 counts per minute.
One revolution is 8192 pulses.
So, per minute I will have

The halui interface for FO and SO is a little different from axis.N
jogging where there are separate scale and enable pins (axis.N.jog-scale

volunteering :)
I've uploaded an minor fix to the ArcBuddy G-Code generator to the wiki site.

I looked over all of the info all of you recommended and based on what
you have shown me I think I can make this work! Thank you very much.
Looking at the WIKI it says to use lspci -v to find the address of my
parallel port. I have a Dell Diminsion 8200 I am working with with an on
board port and
