Hello, folks!
I wanted to ask, if there is some nice place with a sample configs for
7I43 card?
Tomorrow might be the day, when I would like to get some movement in
the newly built robotic arm, but I just realized, that I have not yet
found out, how to set up the 7I43 card - this is my first time

Thanks Lawrence,
I know that it has been operating in half-step mode. I've asked the
manufacturer to send me a spec sheet to see if I can get to the bottom of which
type to use. I seem to remember (it was more than ten years ago) that there
were four phases per motor when in half-step mode.

I think the OP wants to drive stepper motors using four digital lines for
one stepper motor;
A, B, C, D phases, much like one would directly drive a LM298.

Lawrence,
Is this driving conventional steppers or something
different. Is it a better system than microstepping?

Hi Mark,
I am not sure what you are referring to by the term phase drive.
I use my mill and lathe with stepgen set to stepping type 2 which is
quadrature drive ( drive waveform is identical to a quadrature encoder )
Sometimes this mode and some of the higher stepping type modes get
referred to as p

A quick question. I have EMC2 controlling 3 different machines through
step/direction drivers I also have an older phase driver which is connected to
a small lathe using TurboCNC I believe I have read that EMC2 will indeed work
with phase drives but am having a hard time finding info. Any ideas
I just did a piece of python with ppdev.
The author strongly advised to unload lp since it "claims the hardware for
itself".
Does that make sense at all?? in this setup??

Four drivers are normally loaded; lp, ppdev and parport_pc and parport.

This sounds like 2 sets of hardware fighting each other, I mean when you
made the second port.
What about switching the port at 0x378 off?
or alternatively you might also try to restart parport-pc with just the
portaddress you have set in the bios.
I unfortunately do not know the parameters neede
