john,
i wasnt aware that emc used floats ther
it is unusual in cnc to do so, but thats an observation
the 'nice number' refers to the numerator and denomimator
which are outside if emc
which are inside the driver
unless these 2 are nice numbers ( ints divisible by 4 )
then the home pulse
Hi
I presume that the network card will be dedicated, as the parport is, and
only use a simple packet structure.. If one wants to connect to the
internet, then you'd use a seperate USB link or a second network card if
possible. That way there'll be no surprise jamming.

Roland Jollivet
Hi John
I will make some tests today and report the results
back, thank you for your help.
Regards.

Dear all,
Thank you for them help! I solved the problem. I use John Kasunich
suggestion to check the encoders. It is really 8000 count/rev, I use it
to calculate the INPUT_SCALE and using HALmeter and SANYO DENKI
softeware to check the encoder pulse in same value.

As I said before maybe the way to ease into this is just support 1 or a few

Thanks to Dave, John Wayne for the responses. It was helpful.
A good option would be to fit a sander on the CNC machine. That will
considerably speed things up.
I will also see if a simple bead-blasting wont do the job.
emc has an X tool offset for lathes, but doesn't presently have a Y tool
offset.
Adding a Y tool offset involves touching a lot of code, from the tool
table parser to the interpreter to the user interfaces; it's not to be
undertaken lightly.
If someone contributes a patch we'd sure look at

Jeff is exactly right. If you could align them in Y, so you can get
by with just X/Z or X/W offsets, you'd be set.

andre,
do you mean an X,Y,Z C tool offset?
and keep the same program
knowing tool 1 is 'center'
and tool 2 is dx-1 dy-2 dz+4 ? ( i see no use for dc here, for orienting
a drill or jet )
( tool 2 is mounted forward left of tool1 and longer )
thanks, good thoughts

You have the 200k gate version, not the 400k gate version.
I found this out by looking at the error output on line 264 of your pastebin

Hi,
. and it will be called ENC rather than ppmc sorry just
couldn't resist. ;-)

ps. have at it a newer detached controller interface would be really
nice. :-)

I couldn't make much sense of this one, and it is from 2002.
Peter,
What EPP mode are you using and what type and length of cable do you have
between the 7I43 and Parallel port?
The available parallel port modes in the BIOS are Output only,
Bi-directional, EPP and ECP. It is set to EPP, but I do not see a further
selection for mode of EPP. I think we
