Well, there are of course two approaches to this. One of them involves
a
soldering iron... I'm not a programmer by any stretch of the
imagination,
Tim, make an adapter with a male and female DB-25 plug. Sort of a pass
through connector that crosses signals to fit what you need. I have made
a
few to adapt controllers that were using Dancam and then Maxnc. You
could
pull it in and out of the input path as you test all these programs out.
I thought of this too, but just never typed it. I think that at this point
the best thing to do is figure a way to accommodate all the possible
pinouts with parameters in the .ini file. I'll get Fred to read this thread
and see what he thinks is a good way to proceed. Until then your adapter
idea is the best solution.
To be honest, you are the first person
to control a stepper machine with the EMC.
Now you tell us! :-) The list has been quiet this weekend. I figured
everyone was busy setting up their Linux machines like me. I just got
Redhat 5.2 yesterday and have gone through some of the same things Tim
has
been through, but not gotten as far.
When I read this I immediately thought of the movie _The Flight of the
Pheonix_, 1965. In this an airplane is forced to crash land in the desert
and one of the passengers claims to be an aircraft designer and formulates
a plan to build another plane from the wreckage of the first. When they are
nearly done it is discovered that the engineer is a designer of MODEL
airplanes, a fact he neglected to mention. The captain of the plane (Jimmy
Stewart) is furious and confronts the engineer who is a quiet bookish type.
The engineer defends his idea saying something like, "Well, the principles
involved are essentially the same..." It's a good movie, not like today's
stuff.
I read in one of the READMEs that kernels can be compiled on other
machines
and then inserted into a seperate system. If it could be pulled off for
this, (enhanced RT Linux +Redhat 5.2) it would be a real timesaver.(Fred,
Matt, hint hint ;-) )
I'm happy to send you mine, but it's somewhat specific for the hardware you
have. I'm also happy to compile you one to suit your needs (I run Linux on
a 350MHz P2 with 128MB RAM), but I need to know a bit about your system. If
you have an especially slow system this is a good idea, but you'll miss out
on the learning experience of rolling your own.
I have been watching this thread and am saving all the notes. I hope to
be
the second one to run the stepper EMC. Thanks for all the insallation
advice Matt and Tim!
Let me know where your at in the process and I will do what I can to get
you going.
