1)What does it depend? how can we solve it?

I'm not sure, looks like you've not included all the required files in the build.  You should have 11 files.

2)Furthermore, we wonder if we can go from 1 to 2 without changing the code (?)
oh, and we
rstep card is excellent, but for us we use the largest cnc is not suitable.

what do you mean by from 1 to 2?

3)we need to restore basic functions step / dir / enable ... where we
have to work for you?

You can redirect the step/dir/enable to the spare header on the PCB and connect that to a secondary stepper controller that can handle more power.

4)how do I add features without ruining the times?

what features?

5)what is the maximum step frequency?

not sure.  I'll have to run some tests.

hi. first of all I apologize for my English, I'm Italian and not speak it well.
rstep the project is really fantastic!
rstep I saw, I and my friend we bought an Arduino mega.
we have the intention to cooperate and continue with your project,
which is very interesting.

but we have some questions ... a lot ...

when we try to check the firmware, arduino knows us many errors:

Thank you for reply, you're very fast!

1) i have 13 file in the sanguino version and 11 in the arduino one.

sounds about right. still, it looks like something is not setup right in your arduino project.  did you change any filenames?  what version of the arduino software are you using?

2) excuse me, i've used google translate for some parts of this mail. The question is "Can we go from arduino/sanguino whithout changing the code?

one version is for the arduino, one is for the sanguino - most of the code is identical but additional functions exist in the sanguino code. 

3) i've found this file http://reza.net/wiki/images/6/6f/RStep_v3_dorkbotbw.pdf in the wiki...i'm sorry for disturbing you with this stupid question.

what is the question?

4) for example... If i want to expand i/o pins for use all of arduino mega...or if I want to implement some PLC features...or other... (ethernet for example)

I'm afraid if I post some new features i Spoil the axes synchronization.

it depends on how your implementing it.   i want to add support for Ethernet as well and there are some ways of doing this.  tell me what you have in mind and I'll see if I can help you.

6) rstep have lookahead?

no, but that's high on my TODO list - i want it to be able to ramp speed up and down as well.

7) what are the next things you want to add? (i'm curious :-) )

see above :)

Reza

Best regards, Davide Bortolami

Hi Davide,

If you use the sanguino version, then I suppose you have to delete the rStep.pde file, because this is for the arduino one. For sanguino rStep_644.pde what you need only. Having both files caused errors for me too.
