Forward Step / Backward Step - Vexta Question

I am I correct in assuming that StepConf cannot set up driver for a forwardstep and backwardstep pins such as the older Vexta drivers for parallel port use?

I have found very little info, but this:
forum.linuxcnc.org/38-general-linuxcnc-q...s-with-cw-ccw-signal

I've written a 3,000+ line serial-port command-line Arduino Stepper test program, and yet I am not confident that I can set up a motor with Linux CNC.

I dont think stepconf can set the step type but its easy to do in the hal file section that loads the stepgen component

The stepgen manual page explains how to do this:

man stepgen

Thank you PCW...

...but I looked over some of the documentation for HAL and Stepconf; it looks like a real complicated, sparely documented, nightmare : (

That's why I posted the original post.

I think HAL is quite well documented as is the stepgen component. in addition,
there are HAL tutorials to get you started, for example:

linuxcnc.org/docs/html/hal/tutorial.html

l also think that as a simple setup tool stepconf does OK for most people but for more unusual LinuxCNC
configurations or customization you need some understanding of hal and components

DId you read the stepgen manual page and look at the (stepconf created) hal file?

I am looking at the HAL tutorials. It's difficult for me to get a lay of the land. Yikes, there's tread management on the first page of the tutorial. Do certain things have to be loaded? Are there kernal-module depends?

Looking at a StepConf's GUI, those are the only settings I am interested in, well that and the ability to set for stepforward/stepbackward.

AFAIK, I am not going to be able to use stepconf to created/modify the HAL configuration for my set up. If there were a forward-step / backward step option, I wouldn't have to mess with HAL in the first place.

It's regrettable that what I have seen appears a very flat non-tree way of doing things. In other words, why should a user see low-level motor winding waves--and higher level motor-driver settings at the same time?

Andypugh, thanks I have seen that about stepgen.

Thank you Andypugh.

I did understand that Stepconf was a utility that likely just sets settings.

But....

It's still not at all clear how the HAL in large is supposed to be human interfaced with. In other words, it appears that, the incantation: loadrt stepgen step_type=1,1,1 will cause a temporary change in the system, which will also be wrote to a file, but if the system is saving out the state settings, more akin to an old Quake (game) config.cfg than a fstab or a sources.list, then we aren't going to be able to put organized notes in it, are we?

And yet, we are not loading with loadrt, the thing (stepgen) the modifies the system?

LinuxCNC is quite a novel system. Though, the settings are so utterly granular that even as someone who wrote a command-line stepper interpreter myself, who has some Linux experience, I don't know if I am going to be able to set up my system.

LinuxCNC's complexity and perhaps it's power are unprecedented. As someone who wrote technical documentation professionally, I should think that most users would need clearer documentation.
