Jobs ruined after long run

[JAZZCNC]

In a like for like world what would be its competitor so I can glean a bit more info about specs etc, if that's possible :-)

Well first you need to tell me the spec of what you have exactly because I'm just working on the little I know about those machines.

But what I can tell you for sure is what minimum feeds I would expect from any machine built using decent electronics and components.

If 5mm pitch ballscrews with 50Vdc drives running on approx 44Vdc and using parallel port then I'd expect at least 3500-4000mm/min cutting speeds and 5000mm/min rapid speeds. If same setup but with 10mm pitch then nearly double those speeds.
With Decent external motion control card then even higher speeds could be run like below will show. The only difference between these figures above and those achieved below was I used Cslabs IP-M motion controller.


To give some Idea of type of feeds that setup should give. Not so long ago I converted well used Denford router which used 5mm pitch and fitted with 50v digital drives running 44Vdc and it could reach well above 10,000mm/min. It wasn't run or tuned to work at those feeds to give very healthy safety margin but hopefully it shows what can be achieved with that kind of setup.
