Just an update. Testing of the prototype shows 100% reliability so far on rapids, feeds, jogs and of course G31 - which is nice.

ToDo:

Currently has to be hard coded for a given machine - need to make it user configurable.
Currently can handle a max step pulse rate of 100KHz - need to get this much higher for those with V high step counts. (Ya-Nvr-No - 250,000 steps per inch? really? - at (say) 400 in/min rapid - that's 1.6MHz - is this correct?).

Cheers Craig.

Made more progress this afternoon. It's now completely configurable via USB. I think maybe I'll leave it at the 100KHz limit for now unless there's any interest to have it cope with higher step frequencies.

A question: The USB hardware I'm planning on using for the machine config interface requires SP3 for those using XP. Do any of you see this as a problem? i.e. for those using XP, are you using SP3?

Am running SP3, though I'm sure that win 7 would be next if hardware failure and I had to get back online.
Id heard no support for XP from microsoft any longer, so not even sure updates are available.

I am running XP SP3 on all our machines -desktop and CNC. I fail totally to see why I should change (except maybe to Linux when Mach4 is released).

Cheers

nobody says you have to change versions, mach3 works great for the most part, if it works, live with it and be content. As I've heard many times "If it ain't broke don't fix it." Hell at times I still play with CNCPro, (DOS Based cnc) works fine for a lot of things.
