Hello to Ahmed.
I acknowledge that the advice to you from the superior metalcutters of
this email society have value, but I suggest a different approach.
1. Download a copy of the EMC - Hardy Heron ISO, and install it on a few
computers.
1.1 This will give you local copies of the EMC2_Users_Manual and
EMC2_Integrators_Manual.
Searching the manuals using "Find" is an option to searching a
remote database of the same manuals.
I have never searched the EMC2 archives, so I cannot advise on
how efficient searching the archives is.
1.2 You will have copies of EMC2 on each computer you do an install on.
Experiencing EMC2 is needed for you to succeed.
1.2.1 Put the diagrams of your drive control schemes on your
laps, and have a spare piece of paper for writing on.
Start EMC2.
Choose Machine / "Show HAL Configuration" to search
for elements of your drive control schemes.
You will find EMC2 is very extensive.
1.2.2 Choose Machine / "HAL Scope" to verify the values you
set for these elements.
1.3 The parallel port is referenced in the EMC2_User_Manual pdf in
section 8.1,
and the example of loading the software driver for the
parallel port is in section 8.1.1
I suggest finding a parallel port break out board for testing
and experimenting.
1.4 Make a list of HAL RT components, (which you can split up among
your team members),
Components needed for your drive control schemes will be found.
2. I do not know if you are Computer Science people or Engineering students.
So.
I will assume you are Computer Science, and you have not had courses
in controlling machines.
(Such is the Computer Science curriculum where I live).
You are warned that the parallel port will not drive significant
electrical loads.
The Pico and Mesa boards referred to in previous messages are set up
for you to plug into parallel ports.
From here on, we can sympathize, and suggest, but it is you doing
the work.
You will then need to supply non-computer-friendly voltages to these
boards, and connect the boards to the supplied stepper motors.
(If you are on the Engineering side, or have had machine controlling
courses, then I deeply and sincerely apologize for insulting you).
For project and school related stuff, I was advised to have one lab book
to keep everything in,
and put an envelope with a securely closable flap glued to the back of
the notebook. Everything you could not write into the notebook or glue
into the notebook went into the envelope. It was a central repository
of project information. Different people have different documentation
styles, so negotiate a minimum standard.
Documentation is your first chance to try something out.
It is also the way to communicate with people when you have finished the
job, and left the project.
All projects come to an end.
Your professional reputation will be enhanced by good directions to the
technician who will have to repair or maintain your work.
Good luck on your project. It is the start of your profession outside
of school.
When bringing problems back to this email forum,
please list the exact error messages from the software,
and a description of what you expected to achieve.
The people of this email forum are excellent people, besides being
excellent EMC2 machinists.
James Isaac.
