Benergy,

A macropump is a marcro that runs under mach in a loop manner.  It is running all the time.

I am away from you machine now and do not have access to the macro, but I did it following the guidelines in the wiki for making a pendant using a modio.  All the procedures are the same, it is just that inputs pins are not set to port 0, but to the actual port you are going to use.

Enclosed find the link. http://www.machsupport.com/MachCustomizeWiki/index.php?title=Touch_Screen_and_panel_controls_using_ModIO

Benergy,

I believe the part I bought was item # GH3072-ND from digikey, at $4.70.  http://lgrws01.grayhill.com/web/images/ProductImages/I-51-52.pdf  If  I was to do it again, I would get one that would also have a switch, so I could toggle between low and high resolution.

You will connect the encoder outputs to input pins in your parallel port.  Then configure this pins in mach as OEM Trig pins.  Then write a macropump that will read this signals and produce the appropriate OEM codes for fedrate up and down.

Benergy,

I control the federate manualy using a low resolution encoder (about $4 from digikey).  This requires 2 input pins from your parallel port.

I like your “feedrate compensation”, I will work on that.  I guess you would need a device that will sense vibration and will output a signal that will be processed by a macropump running in mach.

Bryan,

1. Minimum computer? It depends on the performance you need.  I would not use anything under 1.2 Mhz. For high speed (45khz) and enhanced pulsing, use a high end computer.

2. Mach version? Use Mach3, it is mature, safe, stable, tested, robust, supported, full of features, etc…

3. Pinouts:  You can assign them freely. On port one,    output pins 1,2,3,4,5,6,7,8,9,14,16,17 and input pins 10,11,12,13,15.  On port two output pins are 1,2,3,4,5,6,7,8,9,14,16,17 Or, 1,14,16,1. Input pins 10,11,12,13,15. Or 2,3,4,5,6,7,8,9,10,11,12,13,1. On the second port you may choose to use pins 2-9 for input, that way you can use lots of inputs. Check out my site, I think there is info that you will find useful for your setup. http://cnc4pc.com
