I am not sure this is the correct question for me to try to answer because I am not using a 5i25, I have had good results so far with cnc4pc's C1G interface card. It may not be capable of as many pre-programmed functions as the 5i25 as it is "programmed" with jumper clips. Very limited, but versatile too, just not in the sense that the 5i25 is. When using something along its (C1G) lines, the choice of pin numbers vs function assignments is purely at your convenience given the limits of the std parport as some pins in the normally initiated condition are input only, and more are output only. With then 5i25, those limits disappear from what I can read. That can be quite an advantage but also appears to require programming firmware to be loaded. I am fond of wiring things up with a 4 wire cable per device controlled, with the stepper motor drivers outputs and encoder signals in a shielded "Star-Quad" style microphone cable. The version I get from Clark Wire & Cable in the Chicago area has what seems to be an oil immune outer jacket (in your choice of several colors) where the shield is NOT connected at the machine end to prevent the noise injecting formation of "ground loops" and is actually pretty flexible, or for outputs such as the spindle controls I like to use a 4 wire flat ribbon cable the shack sells on spools, 50 foot IIRC. But its a solid conductor & I wouldn't call in flexible in the same sense. The stepper driver signals, all in the same box with this interface card, are all controlled by short pieces of that flat ribbon cable as I've found the best way to handle the dirty environment is to put all that in one box I've made from heavy, 1/4" and 1/8" thick alu plate, with individual fans on each motors driver, and all the I/O I need brought out to a long nylon terminal strip via a notch in the cover that passes several pieces of this 4 wire ribbon, all 'gooped' in place so the cover being swung on two of its retainer screws isn't likely to guillotine the wires. This box, when completed, will be well sealed against swarf, and if it gets too warm, a std 120 volt rotron fan does a great job of cooling the whole box. This particular interface has all I/O tallied by super bright LED's which can serve as a troubleshooting tool while wiring things up. In fact, I cut a recess above where it is mounted to the lid panel of this box, and have fitted a lexan cover that will be, when everything is finally wired up, gooped in at about 4 places so the LED's will be visible in normal operation. What you wire to where is entirely up to you within the constraints of the ability of that particular pin, if you are outputting a signal then obviously your hal file needs to steer that signal to an output pin, conversely if this signal is an input, then a pin capable of input needs to be wired to this signal both in the external wiring you connect to and in the internal .hal files "wiring". However, I agree 200% with the relative lack of doc's for the hal stuff. The loadrt command is simple enough, and so is the setp, meaning set a parameter for that named function to work with when it is executed. The net command appears to be how one does the internal 'wiring', at least that is what I have deduced from the few examples. But really, the explanations as to how an individual module of code that is loaded by the loadrt command, have been so emasculated as to be less than useful to those of us, who are functioning as the 'system integrator' in our own home shops, where each new function needed is so poorly described in the hal manual that we have to come to this list and ask if anyone else has managed to 'figure it out'. There are, I think, advantages for the developers who then hear who is having what sort of trouble, but then its quite often only the developer that wrote that code who can begin to tell us frogs how to use it correctly. His having to repeatedly teach us frogs I am sure wastes more of his time than he might have used to fill out to at least half a page, each modules description of what it can do, and at least another paragraph on the effects of each parameter that code module needs. But maybe that is just me getting stupid in my dotage too. I'll let others be the judge of that. I do get 'told off' occasionally. ;-) > On Thu, Apr 12, 2012 at 10:11 AM, Viesturs Lؤپcis > > <viesturs.la...@gmail.com>wrote: > > 2012/4/12 Erik Friesen <e...@aercon.net>: > > > I don't mind writing my own, its just that details are so sketchy > > > and I don't know where to get information.
